2-Phosphonobutane-1,2,4,-tricarboxylic Acid Uses:
Water treatment:
One of the most important applications of this material is in water purification.
2-Phosphonobutane-1,2,4,-tricarboxylic Acid is used as an anti-corrosion and antiscalant in industrial units.
Water used in cooling systems and other industrial equipment contains hardening agents and impurities such as calcium carbonate and copper ions.
These impurities cause many problems, including sedimentation in pipes and other paths that deal with water, and also cause corrosion in the system.
Amino trimethylene phosphonic acid (ATMP) and Etidronic acid (HEDP) also have this capability, but there are two barriers to using these substances:
Limitations in the solubility of their salts and their low resistance to oxidizing agents
Anticorrosion and antiscalants:
2-Phosphonobutane-1,2,4,-tricarboxylic Acid has more power than other phosphonates as an anti-corrosion and anti-scaling agent.
2-Phosphonobutane-1,2,4,-tricarboxylic Acid can be used to control the deposition of calcium carbonate.
In addition, 2-Phosphonobutane-1,2,4,-tricarboxylic Acid is very useful in harsh conditions and very high temperatures, and high alkalinity.
Cooling systems and industrial water treatment units:
In systems where water plays a key role as a cooling agent, the presence of substances such as calcium ions causes deposits inside the equipment, which blocks the passage of water and makes the system inefficient.
The best way to solve this problem is to use antiscalants such as PBTC.
Industrial detergents:
One of the most important applications of phosphates is in the production of detergents.
The use of these materials has the following advantages: reducing hardness and preventing the formation of sediment and dispersion of contaminants and controlling their deposition.

Abstract:
Industrial water systems often suffer from undesirable inorganic deposits, such as calcium carbonate, calcium phosphate(s), magnesium silicate, and others.
Synthetic water additives such as phosphonates and phosphonocarboxylates are the most important and widely utilized scale inhibitors in a plethora of industrial applications.
The design of efficient and cost-effective inhibitors, as well as the study of their structure and function at the molecular level are important areas of research.
This study reports the crystal and molecular structure of PBTC (PBTC = 2-phosphonobutane-1,2,4-tricarboxylic acid), one of the most widely used scale inhibitors in the cooling water treatment industry.
Triclinic PBTC monohydrate crystallizes in the P 1 space group with cell dimesions, a =7.671(1) Å, b = 8.680(1) Å, c = 9.886(1) Å, α = 65.518(2) deg, β = 71.683(2) deg, γ = 76.173(2) deg, V = 564.20(11) Å3, and Z = 2.
Bond distances in the -PO3 moiety are 1.4928(10) Å for the P=O double bond and 1.5294(10) Å and 1.5578(10) Å for the two -P-O(H) groups.
P-C and C-O bond lengths fall in the normal range.
A network of hydrogen bonds are formed between the water molecule of crystallization, the -P-OH and the -COOH groups.
2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) is an antiscalant that is widely used in reverse osmosis (RO) systems.
Because of its high concentration in RO concentrate, eutrophication risk and anti-precipitation properties may affect subsequent treatments, therefore treatment strategies are needed to eliminate such substances.
In this study, PBTCA was degraded by ozonation.
The results show that PBTCA reacted with ozone molecules and hydroxyl radicals, with second-order rate constants of (0.12 ± 0.002) and (7.83 ± 1.51) × 108 L mol−1 s−1, respectively.
The phosphorus in PBTCA (PP) was transformed into organic phosphorus except for PBTCA (PO), and inorganic phosphorus (PI); PO was further transformed into PI.
The changes in the concentrations of these phosphorus forms were investigated by model simulation.
Simulation showed that the rate of PP transformation into PO was 5.5 times higher than that into PI.
PBTCA was ozonated much faster at alkaline pH than at acidic pH.
This is ascribed to different amounts of ozone molecules and hydroxyl radicals, and their different reaction rates with PBTCA.
Furthermore, anti-precipitation property was reduced during ozonation, as shown by the amounts and morphology changes of the precipitates.
PBTCA concentration for 50% anti-precipitation (AP50) did not change during ozonation, indicating that the transformation products generated during ozonation did not have anti-precipitation effects.
Phosphorus in PBTCA was removed by ozonation–coagulation treatment.
Total phosphorus and inorganic phosphorus were removed efficiently by using ferric chloride as a coagulant.
The coagulants tended to bind with inorganic phosphorus to form flocs.
Meanwhile, flocs were more easily to aggregate and precipitate as anti-precipitation effect was gradually removed, thus more phosphorus was removed.
A combination of ozonation and coagulation removed PBTCA effectively and simultaneously reduced its anti-precipitation property and phosphorus.
2-Phosphonobutane-1,2,4-tricarboxylic acid is(PBTC) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems.
Phosphonocarboxylates as a member of organophosphorus compounds have C-P and P-O bonds in their structures.
PBTC is mainly used as carbonate scale inhibitor (CaCO3), sulphate scale inhibitor (CaSO4), corrosion inhibitor of low alloyed steel, effective and well applicable in alkaline hard-waters, excellent and resistance against chlorine, usable in detergents and cleaning agents and also a unique stabilizer of bleaching substances.In the present work PBTC is synthesized using dimethyl hydrogen phosphite, dimethyl maleate and methyl acrylate, overall yielding 86.5% product.

Abstract:
Applications of nanoscale zero-valent iron (N-Fe0) and modified Fe0 with 2-phosphonobutane-1,2,4-tricarboxylic acid (P-Fe0) prepared by borohydride reduction for removal of Cu2+ in water are investigated under a variety of experimental conditions.
Characterizations with X-ray diffractometer, scanning electron microscopy and transmission electron microscopy confirm that N-Fe0 and P-Fe0 have a core shell structure similarly.
The uptake experiments investigated the effects of the dosages of N-Fe0 and P-Fe0, pH and the adsorption kinetics.
The results showed that the ratio of removal efficiencies is more than 90% with the condition of initial concentrations of 10.0–70.0 mg/L, pH of 7 at 25 °C and the adsorbent of 0.4 g/L N-Fe0 and P-Fe0.
Within the applied conditions, the order rate of Cu2+ adsorption kinetics equation on the N-Fe0 and P-Fe0 was the pseudo-second.
According to X-ray photoelectron spectroscopy results, Cu2+ ions were removed primarily via a redox mechanism that resulted in the formation of Cu0 and Cu2O.
The contact of N-Fe0 and P-Fe0 with aqueous media caused extensive formation of iron oxide.
The research reveals that Cu2+ can be efficiently removed by the means of N-Fe0 and P-Fe0 in solution, and the appropriate factors, involving pH value and the dosages of Fe0, were important keys in the process, and the modified Fe0 will be extensively utilized for the removal of Cu2+ from wastewater.
