Embodiment 1
[0016] This embodiment provides a method for producing tert-butyl glycol ether. Using liquefied petroleum gas and ethylene glycol as raw materials, and the mass percentage concentration of isobutylene in the liquefied petroleum gas is 60%, the addition reaction is carried out in a tubular reactor to synthesize ethylene glycol mono-tert-butyl ether and ethylenedioxide Alcohol bis-tert-butyl ether.
[0017] The tube-and-tube reactor used is equipped with a stainless steel tube with a length of 2.5 meters and a nominal diameter of 50mm. The material is 316L. The outside of the tube is a jacket. The jacket contains circulating hot water for heating to provide the reaction system. Heat source.
[0018] Fill the strong acid cation exchange resin (D-005 cation exchange resin catalyst produced by Dandong Mingzhu Special Resin Co., Ltd.) into the tubular reactor and reserve a space for thermal expansion. After the main catalyst is filled, the tubular The reactor is fixed. spare.
