Sodium lignosulfonate Chemical Properties,Uses,Production
Sodium lignosulfonate is using as water reducing agent
Lignosulfonate is a water-soluble multi-functional polymer electrolyte, belonging to a lignin sulfonate and having the capability of dispersion of biological slime, oxidizing iron scale and calcium phosphate scale. 
Sodium lignosulfonate can also form a stable complex with zinc ions and calcium ions.
Sodium lignosulfonate and calcium lignosulfonate are commonly used water-reducing agents in multifunctional concrete waterproofing agent. 
When water-reducing agent is added into concrete, the hydrophobic group of water-reducing agent will be adsorbed on the surface of cement particle while the hydrophilic group will be pointed to the aqueous solution to form a single molecule or multi-molecule adsorption film, making the cement particles be dispersed due to the rejection from the same surface charge, being released of excess amount of water between particles in order to achieve the purpose of water reduction. 
At the same time, due to lowering the water surface tension and the interfacial tension between the cement particles, while maintaining the same fluidity, it will correspondingly cause reduction in water consumption, and thus also play a role in water reduction. 
Sodium lignosulfonate can significantly reduce the hydration of concrete, reduce porosity and increase the density of concrete, thereby greatly improving the strength and impermeability of concrete.
Lignin sulfonate is a series of natural compounds of molecular weight of 1000~30000. 
Sodium lignosulfonate is produced from the wasted pulp after fermentation alcohol extraction, followed by the neutralization with alkali. 
There are mainly calcium lignosulfonate, sodium lignosulfonate and magnesium lignosulfonate, of which the most widely used calcium lignosulfonate, is made of pulp waste. 
This kind of water-reducing agent is rich in raw material with simple manufacturing process and low price, and is widely used in domestic, accounting for 80% of the total output of water reducing agent. 
But Sodium lignosulfonates effect is not very good with bleed air and retarding effect, belonging to the ordinary water reducing agent, and will yield excellent result if used in combination with strength agent.

Mechanism of action
Most of the water-reducing agent is surface-active agent. 
Therefore, the mechanism of sodium lignosulfonate is the effect of surface activity.
Surfactants are organic compounds whose molecules have both hydrophilic and hydrophobic groups. 
Hydrophobic groups are various alkyl or alkaryl groups; hydrophilic groups are typically salts capable of dissociating ions. 
Depending on the dissociation of the ions by the hydrophilic groups, the surfactants can be classified into anionic surfactants; cationic surfactants; amphoteric surfactants; and nonionic surfactants. 
When the surfactant is added into the aqueous solution, the surface tension (water-gas phase) and the interfacial tension (water-solid phase) of the water can be reduced, and the surface activity can be reduced. 
From the physical and chemical sense, the surface active agent refers to materials, when added to the aqueous solution, has its surface solution depth be greater than the depth of the solution itself, leaving the surface tension reduced.
After addition of the water reducing agent, lignosulfonate to the concrete, the water-repellent group of the water-reducing agent is directly adsorbed on the surface of the cement particles, and the hydrophilic group is directed to the aqueous solution, which makes up the adsorption film of single molecule or multi-molecule. 
In the case, the cement particles are repelled and dispersed due to the same charge on the surface, releasing from excess water between particles to achieve the purpose of water reduction. 
Due to lowering the water surface tension and interfacial tension between the cement particles, while maintaining the same fluidity, the corresponding reduction in water consumption, and thus also play an effect on water reduction.

Chemical properties
Sodium lignosulfonate appears as brown powder or liquid with no special smell. 
Sodium lignosulfonate is non-toxic, being easily soluble in water and alkali. 
Sodium lignosulfonate undergoes precipitation upon coming across acid. Has a strong ability to disperse.

Sodium lignosulfonate uses:
Sodium lignosulfonate is mainly used as cement water-reducing agent, leading to the diffusion of group of cement so that the water content is precipitated out, increasing its mobility, thereby reducing the mixing water, and saving cement. 
When Sodium lignosulfonate being used in the formulation of the oil drilling pulp, Sodium lignosulfonate can be used to reduce mud viscosity and shear force to control the mobility of drilling mud. 
In this case, the inorganic mud and inorganic salt impurities remain in the suspension state in the drilling, preventing the mud flocculation. 
Sodium lignosulfonate also has prominent salt resistance, anti-calcium and high temperature resistance.
Sodium lignosulfonate can also be used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing and so on

Sodium lignosulfonate production method
Sodium lignosulfonate is the same to the water reducing agent MY.
Calcium bisulfite pulping process: the sulfite or bisulfate contained in the pulp slurry binds directly with the hydroxyl contained in the lignin molecules to produce lignin sulfonate. 
10% lime milk was added to the waste liquid and heated at (95 ± 2) ° C for 30 min. 
Have the calcium solution stand for a while and filter out the precipitate, wash with water and add sulfuric acid. 
Filtrate to remove calcium sulfate. Na2CO3 was then added to the filtrate to convert calcium lignosulfonate to sodium sulfonate. 
A reaction temperature of 90 ℃ is appropriate. After 2h of reaction, stand, filter to remove impurities such as calcium sulfate. 
The filtrate is concentrated, cooled and crystallized to obtain the product.
Take the papermaking waste liquid obtained from the alkali pulp as raw material. 
First add concentrated sulfuric acid to the waste solution to about 50%, stir for 4~6 h. 
And then use lime milk, sedimentation, filtration, beating and acid dissolving, add sodium carbonate for conversion, concentration and drying to get the final product.
Take the waste liquid obtained from grass pulping method as raw materials.

Air & Water Reactions
Water soluble.

Sodium lignosulfonate reactivity Profile
Sodium lignosulfonate is an oxidizing acid. 
Oxidizing acids are generally soluble in water with the release of hydrogen ions. 
The resulting solutions have pH's of less than 7.0. 
Materials in this group react with chemical bases (for example: amines and inorganic hydroxides) to form salts. 
These neutralization reactions occur as the base accepts hydrogen ions that the acid donates. 
Neutralizations can generate dangerously large amounts of heat in small spaces. 
The dissolution of acids in water or the dilution of their concentrated solutions with water may generate significant heat. 
The addition of water acids often generates sufficient heat in the small region of mixing to boil some of the water explosively. 
The resulting "bumping" spatters acid widely. 
These materials have significant ability as oxidizing agents.
that ability varies (for example, from high for nitric acid to low for sulfuric acid and most sulfonic acids). 
They can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. 
Like other acids, materials in this group can initiate polymerization in certain classes of organic compounds. 
Their reactions with cyanide salts and compounds release gaseous hydrogen cyanide. 
Flammable and/or toxic gases are also often generated by their reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. 
Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. 
Acids often catalyze (increase the rate of) chemical reactions.

Sodium lignosulfonate (wood pulp) is the extract from the bamboo pulp process, which is obtained by concentration, modification, pulverization, and drying. 
Sodium Lignosulfonate (CAS 8061-51-6) is a light yellow (brown) free-flowing powder that is easy to dissolve in water.  
The properties of the product are consistent and its long-lasting storage cannot be decomposed. 
Lignin series product is a kind of surfactant, a variety of products can be produced by modification, processing, and composition. 
The products which are produced from these things are used for raw materials. 
Experiments have shown that lignosulfonate is very effective in preventing sandy soils and can be used as a fixed agent for desert sand.
Many important characteristics of concrete are influenced by the ratio of water to cementitious materials used in the mix. 
When we lessen the amount of water in concrete, then the cement past becomes more powerful and gives long-lasting results. 
An increase in the quality of the paste will produce greater compressive and flexural strength, lower permeability, greater resistance to weathering, improve adhesion of concrete and reinforcement, reduce volume change due to drying and wetting, and reduce cracking tendencies.

SNF looks like yellowish or brownish powder it is widely used for the preparation of free-flowing and pumpable concrete mixes in the construction industry. 
SNF can be used as a raw material for an accelerator, antifreeze, and retardant compounds in various construction sectors. 
Its high purity characteristic makes the cement particles have high low foaming, high water reduction, and strengthening. 
In addition, Sodium lignosulfonate also improves the mobility and workability of concrete.
The structure turned out to be three aromatic alcohols: coniferyl, alcohol, p-counterpart alcohol, and sinapyl alcohol. 
Completely soluble in water and practically insoluble in an organic solvent.

SNF can easily be resolved glycol, diethylene glycol, glycerol. 
Sodium lignosulfonate also can be resolved in water, slightly soluble in alcohol, but insoluble in carbon-based diluents. 
In addition, Sodium lignosulfonate is widely used in various industries such as agriculture, plastics, and rubber, paper, construction, textiles, oil, and others.
Sodium lignosulfonate concrete has different characteristics; many important characteristics of concrete are influenced by the relationship between water and cementitious materials used in the mix. 
When we decrease the amount of water in the concrete the past cement becomes more powerful and gives long-lasting results. 
An increase in pulp quality will produce higher compressive and flexural strength, lower permeability, and higher weather ability, improve adhesion of concrete and reinforcement, reduce volume change due to drying and wetting, and reduce biases.
