Abstract

本技术采用经典的威廉斯不对称醚合成原理，以二甲基乙醇胺为原料，经氯化，并与醇钠反应，经精馏而获得对称二甲胺基乙基醚产品。

Description

对称二甲胺基乙基醚的合成
技术领域
本技术属于聚胺酯工业，用作发泡的高性能催化剂。
技术背景
目前，该技术产品有美国气体公司生产，其代号为A-1。随着我国聚胺酯工业的发展，高性能催化剂的需求已供不应求，国内虽有小批量生产，但技术落后，成本高，没有竟争力。
发明内容
本技术是以二甲基乙醇胺为原料，经氯化，缩合，精馏而得。工艺简单，操作方便，生产周期短，设备投入小，产品质量高。
实施方按
1.在反应器内投入二甲基乙醇胺和金属钠，使其成醇钠。
2.在反应器内投入氯化亚砜，低温下滴加二甲基乙醇胺，使其成氯化物。
3.在缩合反应器内醇钠和氯花物生成对称二甲胺基乙基醚粗品，经精馏而得。

Claims (3)

1.本技术是以二甲基乙醇胺为主要原料。
2.本技术须经氯化。
3.本技术须经缩合。
