Butyl di glycol is a clear, colourless liquid with a high boiling point, low volatility and a mild, pleasant odour. Its properties are similar to butyl glycol, though it evaporates more slowly. Like other glycol ethers, it has a bi-functional nature, containing both ether and alcohol groups 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, coupling and coalescing 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 di glycol is produced by the reaction of two ethylene molecules with normal butanol (n-butanol) in the presence of a catalyst.

Applications of Butyl Di Glycol
Butyl di glycol is commonly used as a flow promoter in baking finishes such as those derived from urea, melamine and phenol, in lacquers for coil coating and in cellulose nitrate baking finishes; it also reduces the tendency of such products to blistering.
It is used as a latex coalescent in a range of adhesives and water-based coatings, and as a solvent in silk screen printing inks, ballpoint and felt-tip pen inks and textile inks and dyes.
Butyl di glycol acts as a solvent in many natural and synthetic resins, fats and oils, and is regularly used in both industrial and household surface cleaners as a de-greasing agent, in rust removers and disinfectants.
It is an important starting material for a variety of syntheses, being one of the raw materials for the production of butyl di glycol acetate and for the production of plasticizers by reaction with phthalic anhydride. It is also formulated into some insecticides and herbicides, and is a component in hydraulic brake fluid, cutting oils, printing inks and foam extinguishants.
Storage and Handling
Butyl di glycol is incompatible with strong acids, bases and oxidizers.
Improper handling may result in skin and eye irritation and corneal injury. Handle in accordance with good industry practices for safety and hygiene. See product SDS for further information.
