| titleOfInvention | The synthetic method of 2 propoxyl group chloroethanes |
| abstract | The invention belongs to technical field of organic synthesis, and in particular to the synthetic method of 2 propoxyl group chloroethanes.The present invention is under phase transfer catalyst effect, and using ethylene glycol propyl ether and thionyl chloride as primary raw material, reaction rate is controlled by the way that thionyl chloride is added dropwise, crude product is obtained by heating, insulation, then through hydrolyzing, neutralizing, standing liquid separation and obtain 2 propoxyl group chloroethanes.Compared with the prior art, catalyst of the present invention is more efficient, and technical process is easy, and securely and reliably, product yield is high, steady quality, and for product content up to more than 99.0%, yield is more than 98.5%, and production cost is lower, is especially suitable for industrialized production. |
