Butyl glycol also known as 2-Butoxyethanol is acolourless, slightly hygroscopic, neutral, high-boiling, low-volatility liquid with a mild odour that is used as a solvent and starting material for many reactions. In addition to that, it is used as a solvent for aqueous coating systems (water-based paints). Butyl glycol belongs to the family of glycol ethers. Glycol ethers consist of two components, an alcohol andether. According to the nature of alcohol, molecules of this class can be divided into two groups: E series and P series which correspond to ethylene and propylene respectively. Butyl glycol belongs to E series of glycol ethers. Butyl glycol is miscible with water and common organic solvents in all proportions at room temperature. It shows the reactions typically shown by alcohols, such as esterification, etherification, oxidation and formation of acetates and like most ethers, it forms peroxides in the presence of atmospheric oxygen.
