Chemical properties Dipropylene glycol monomethyl ether (DPM), also known as dipropylene glycol monomethyl ether, is a colorless transparent viscous liquid with good solubility. Has a pleasant smell. The product is an environmentally friendly alcohol ether solvent with low toxicity, low viscosity, low surface tension, moderate evaporation rate, good dissolution and coupling ability, completely miscible with water and a variety of organic solvents, and has good composability. Use as a solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc. In industrial applications, dipropylene glycol methyl ether is mainly used as a solvent for paints, dyes and Chemicalbook brakes. In addition, it can be used as an ingredient in cosmetics and personal care products, and as an intermediate in certain electronic chemicals. Because it is able to dissolve well with a variety of substances, it is also often used in the manufacture of other chemical products or as an additive. Production method: 1, 2-propylene oxide is hydrated to produce dipropylene glycol, which is then reacted with methanol. Another method is to react 1, 2-propylene oxide with methanol under the catalysis of BF3, adjust the ratio of methanol, first hydrolyze to dipropylene glycol, and then further react with raw products.
