Description
2-Butoxy Ethanol 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.

Application
1. It works as a solvent in metal cleaning agents, paint removers, lubricating agents, automobile engine cleaners, dry cleaning solvents, epoxy resin solvents, drug extractants for coatings, printing inks, stamp printing inks, oils, resins, and more. It also serves as a stabilizer for latex paint, an evaporation inhibitor in aircraft paint, and for surface processing of high-temperature baking enamel paint, among other uses.
2. It 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.
Storge & Handling
It should be kept stored in tightly closed, grounded containers in a cool area with adequate ventilation, away from normal work areas and sources of heat and sparks, and electrical equipment. At the storage and handling area, workers should use solvent resistant materials.
