Methylated Peg2 Alcohol Pegylated Methyl Alcohol

The ethylene glycol methyl ether series products are high-performance advanced organic solvents, used as solvents and diluents for printing inks, industrial cleaning agents, coatings (nitrocellulose paint, varnish, enamel), copper clad plates, printing and dyeing, etc. It can be used as a raw material for producing chemical products such as pesticide intermediates, pharmaceutical intermediates, and synthetic brake fluids; Used as an electrolyte for electrolytic capacitors, leather making chemical fiber dyeing agents, etc. Used as a textile additive, synthetic liquid dye, and raw material for desulfurization agents in fertilizer and oil refining production.This product is a by-product of industrial production of ethylene glycol monomethyl ether. Mix ethylene oxide with methanol, preheat and add to the reactor. The reaction temperature is 150-200 ºC. The reaction pressure is 1.96~3.92 MPa, and the excess methanol is about 15%. The reaction product not only contains ethylene glycol monomethyl ether generated by the main reaction, but also diethylene glycol methyl ether and triethylene glycol methyl ether generated by the side reaction, as well as excess methanol. The four main components are separated by an alcohol recovery tower and three vacuum distillation towers, and the methanol obtained is recycled to obtain products such as ethylene glycol monomethyl ether, diethylene glycol methyl ether, and triethylene glycol methyl ether.
