Ethylene Glycol Butyl Ether CAS#111-76-2

2-Butoxyethanol is a clear, colourless liquid with ether-like smell.2-Butoxyethanol is usually produced by a reaction of ethylene oxide with butyl alcohol, but it may also be made by the reaction of ethylene glycol with dibutyl sulphate. 2-Butoxyethanol is widely used as a solvent in protective surface coatings such as spray lacquers, quick-dry lacquers, enamels, varnishes, and latex paints. It is also used as an ingredient in paint thinners and strippers, varnish removers, agricultural chemicals, herbicides, silicon caulks, cutting oils, and hydraulic fluids and as metal cleaners, fabric dyes and inks, industrial and household cleaners (as a degreaser), and dry-cleaning compounds. It is also used in liquid soaps and in cosmetics. 2-Butoxyethanol acetate has been reported to be present in air, water, and soil as a contaminant and exposure to it occurs during its manufacture and use as an intermediate in the chemical industry, and during the formulation and use of its products in multiple industrial activities. The acetate form of 2-butoxyethanol is 2-butoxyethanol acetate and also known as ethylene glycol monobutyl ether acetate.

Product Application of CAS#111-76-2

2-Butoxyethanol is a reagent in synthesising 4-butoxyethoxy-N-octadecyl-1,8-naphthalimide as a new fluorescent probe for determining proteins. It is also used as a reagent in synthesising 4-hydroxybenzaldehyde derivatives as tyrosinase inhibitors. It is used widely as a coupling solvent because of its superior coupling efficiency and excellent solvency for resins. Ethylene glycol monobutyl ether (2-Butoxyethanol) is used as a solvent for nitrocellulose, resins, oil, and grease and in dry cleaning.
