Butylglycol is a clear, colorless oily liquid with a high boiling point, low volatility and slightly fruity odour.
As with other glycol ethers, Butylglycol is bifunctional, containing an ether and an alcohol group in the same molecule.
Butylglycol is completely miscible with water and a wide variety of organic solvents.
This excellent miscibility makes Butylglycol a versatile solvent and coupling agent offering excellent performance properties in a wide range of applications.

Butylglycol is bifunctional nature also means exhibiting the reactions typical of an alcohol, ie. esterification, etherification, oxidation and formation of an ether with acetates and alcoholates, which forms peroxides in the presence of atmospheric oxygen.
Butylglycol is produced by the reaction of ethylene oxide with normal butanol (n-butanol) in the presence of a catalyst.
Butylglycol is a flammable material.
Keep the product and empty containers away from heat, sparks and flames.

Applications of Butylglycol:
Selected applications of Butylglycol are described below.
As a low-volatility solvent, Butylglycol can be used to extend the drying time of coatings and improves their flow.
Butylglycol is especially recommended for paints for brush-application based on cellulose nitrate, chlorinated binders or cellulose ethers, because when Butylglycol is applied to dry coatings, it only softens them very slowly.
Small proportions of Butylglycol improve the brushability of, for example, alkyd resin paints and reduce their viscosity.

Butylglycol is also an extremely efficient flow improver for urea, melamine or phenolic stoving finishes.
Butylglycol has proved to be the most effective of a large number of organic solvents tested in a very wide range of aqueous coating systems.
In particular, it improves the properties of the paint by reducing the viscosity peak when oxidatively and physically drying water-based paints, including those for stoveenamelling, are diluted with water.
As a coalescing aid, Butylglycol can significantly lower the minimum filmforming temperature (MFFT) and improve flow in many physically drying paint systems.

Butylglycol improves the evaporation behaviour of the volatile constituents (e. g. in water-based stoving enamels) during hot-air or infrared drying.
Further information on the use of Butylglycol in aqueous coating systems can be found in our Technical Information Sheet “Butylglycol in water-based coating systems”. 

Further applications of Butylglycol are as follows:
-Solvent in printing inks for leather dyes, etc.
-Component in surface cleaners, e. g. to degrease metal surfaces.
-Component in hydraulic fluids.
-Component in drilling and cutting oils (strong solvent).
-Starting material in the production of butyl glycol acetate which is also an excellent solvent.
-Starting material in the production of plasticizers, e. g. by reaction with phthalic anhydride.

Storage & Handling of Butylglycol:
Butylglycol should be stored under nitrogen.
The storage temperature of Butylglycol must not exceed 40 °C and moisture are excluded.
Under these conditions, a storage stability of 12 months can be expected.
As soon as the original packaging is opened, the liquid comes into contact with ambient air and this will cause the formation of large quantities of eroxides and their degradation products.
Opened containers of Butylglycol should therefore be used up as quickly as possible.
Butylglycol is recommended to use nitrogen blanketing for bulk storage tanks.
Only dedicated storage tank and unloading facilities should be used. 

Boiling range at 1013 hPa: 168 – 172 °C
Density at 20°C: 0.8995 – 0.9020g/cm3

Uses of Butylglycol:
Butylglycol use is dominated by the paint industry, which consumes about 75% of all BG produced.
This is because it is a low volatility solvent and therefore extends the drying times of coatings and increases the flow.
Other applications are as a solvent in printing inks and textile dyes and as a component of hydraulic fluids.
Butylglycol is also a component of drilling and cutting oils and is a key component of Corexit 9527, an oil spill dispersant product.

Butylglycol is also a chemical intermediate and therefore a starting material in the production of butylglycol acetate, which is itself an excellent solvent.
Butylglycol is also the starting material in the production of plasticizers by the reaction of phthalic anhydride.
Butyl glycol is also something used regularly in most households, as it is an ingredient in many household cleaning products.
Butylglycol provides very good cleaning power for household cleaning products and also provides a characteristic odor associated with most of these products.

Butylglycol also plays the same role in some industrial and commercial surface cleaners.
Butylglycol is widely used as a solvent and coupling agent in water-based paints, coatings and inks; here Butylglycol improves the flow of products and prolongs drying times.
Urea is an effective flow enhancer for melamine and phenolic oven linings.

Butylglycol is preferred in many products due to its mild fragrance.
Butylglycol acts as a solvent and coupling agent in many waxes, resins, oils and textile dyes and is used in many industrial, commercial and household cleaning products that offer the good cleaning power and fragrance typically associated with such products.
Butylglycol is an important starting material for various syntheses, which is one of the raw materials for the production of butyl glycol acetate, and for the production of plasticizers by reaction with phthalic anhydride.
Butylglycol is also formulated in insecticides, herbicides, pesticides and cosmetics, and forms an ingredient in hydraulic fluids and cutting and drilling oils.

Butylglycol is an organic compound with the chemical formula BuOC2H4OH (Bu = CH3CH2CH2CH2).
Butylglycol has a sweet, ether-like odor, as Butylglycol derives from the family of glycol ethers, and is a butyl ether of ethylene glycol.
As a relatively nonvolatile, inexpensive solvent, Butylglycol is used in many domestic and industrial products because of its properties as a surfactant.

Production of Butylglycol:
Butylglycol is commonly obtained through two processes; the ethoxylation reaction of butanol and ethylene oxide in the presence of a catalyst:

C2H4O + C4H9OH → C4H9OC2H4OH
or the etherification of butanol with 2-chloroethanol.
2-Butoxyethanol can be obtained in the laboratory by performing a ring opening of 2-propyl-1,3-dioxolane with boron trichloride.
Butylglycol is often produced industrially by combining ethylene glycol and butyraldehyde in a Parr reactor with palladium on carbon.

In 2006, the European production of butyl glycol ethers amounted to 181 kilotons, of which approximately 50% (90 kt/a) was 2-butoxyethanol. World production is estimated to be 200 to 500 kt/a, of which 75% is for paints and coatings and 18% for metal cleaners and household cleaners.
In the US, Butylglycol is considered a High Production Volume Chemical because greater than 100 million pounds of this chemical are produced per year.
