diglycolchloroformate - Phosgene synthesis of diethylene glycol bischloroformate
from Wanfang
Author:
Abstract:
In the phosgene synthesis of diethylene glycol bis-chloroformate, diethylene glycol can be added dropwise in the liquid light by dropwise addition. After synthesizing diethylene glycol bis-chloroformic acid ester, the finished product should be obtained by driving light with nitrogen; however, for the traditional diethylene glycol bischloroformate production process, because it is not easy to control the color of the product, it will affect the production quality of the product. Therefore, it should be improved with the improvement measures to optimize the synthesis process, to improve the synthesis quality of diethylene glycol bischloroformate. The following analysis of diethylene glycol bischloroformate phosgene synthesis experiment.
