BUTYL GLYCOL

Appearance : Liquid, Light Colored

Chemical Name : 2-Butoxyethanol, Butyl Cellosolve

Chemical Formula : CH3(CH2)3OCH2CH2OH

Type of Packaging : In Drums

Description and Areas of Usage :

Butyl glycol is a clear, colourless oily liquid with a high boiling point, low volatility and a mild fruity odour. Like other glycol ethers, it has a bi-functional nature, containing both an ether and an alcohol group in the same molecule. It is fully miscible with water and a wide range of organic solvents. This excellent miscibility makes it a versatile solvent and coupling agent which offers excellent performance features in a wide range of applications.

Its bi-functional nature also means that is displays the typical reactions of an alcohol, ie. esterification, etherification, oxidation and the formation of acetates and alcoholates, as well as those of an ether, forming peroxide in the presence of atmospheric oxygen.

Butyl glycol is produced by the reaction of ethylene oxide and normal butanol (n-butanol) in the presence of a catalyst.

Butyl glycol is a combustible material. Keep the product and any empty containers away from heat, sparks and flame. Handle in accordance with good industry practices for safety and hygiene.

Areas of Usage

Butyl glycol usage is dominated by the paint industry which consumes approximately 75% of all the BG produced. This is because it is a low volatility solvent and can therefore both extend the drying times of coatings and improve their flow.
Other applications include use as a solvent in printing inks due to its high boiling point, textile dyes and as a component of hydraulic fluids. It is also a component of drilling and cutting oils and is a major component of Corexit 9527, which is an oil spill dispersant product.

It is also a chemical intermediate and, as such, is a starting material in the production of butyl glycol acetate which is, itself, an excellent solvent. It is also a starting material in the production of plasticisers by the reaction of phthalic anhydride.
Butyl glycol is used regularly in most households as it is a component of many home cleaning products. It provides excellent cleaning power for domestic cleaning products and also provides the characteristic odour that we associate with them. It also plays the same role in some industrial and commercial surface cleaners.

Butyl glycol is most commonly used as a solvent and coalescing agent in water-based paints, coatings and inks where it improves the flow of the products as well as extending their drying time. It is also an efficient flow improver for urea, melamine and phenolic stoving finishes.
Butyl glycol is also favoured in many products due to its mild odour. It acts as a solvent and coupling agent in many waxes, resins, oils and textile dyes, and is regularly used in many industrial, commercial and household cleaning products, where it offers good cleaning power as well as the odour typically associated with such products.

It is an important starting material for a variety of syntheses, being one of the raw materials for the production of butyl glycol acetate and for the production of plasticizers by reaction with phthalic anhydride. It is also formulated into insecticides, herbicides, agricultural pesticides and cosmetic products, and is a component in hydraulic fluids and cutting and drilling oils.

Its most common use is in water-based paints, because it prevents drying and cracking of the paint. Butyl glycol usage is dominated by the paint industry which consumes approximately 75% of all the BG produced. This is because it is a low volatility solvent and can therefore both extend the drying times of coatings and improve their flow. It also has a softening effect. It dissolves polyester and epoxy resin well. It has fabric protective properties on leathers. It is also used in the cleaning industry and cosmetics industry. It is a good component in fire foam manufacturing. It is an important starting material for a variety of syntheses, being one of the raw materials for the production of butyl glycol acetate and for the production of plasticizers by reaction with phthalic anhydride.
