A process is provided for producing bis-(N,N-dialkyl- amino)-alkyl ethers of the formula (R2NR')20, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group having from 2 to 3 carbon atoms. The novel process is effected by a two-step, 'one pot' reaction that utilizes a chloro-containing compound selected from the group consisting of sulfuryl chloride, thionyl chloride and chlorosulfonic acid together with R2NR'ONa as reactants, wherein R and R' are defined above. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes.
本发明提供了一种生产式 (R2NR')20 的双(N,N-二烷基-
氨基)烷基醚的工艺,其中 R 是甲基或乙基,R'是具有 2 至 3 个碳原子的二价亚烷基。 这种新工艺是通过两步 "一锅 "反应实现的,该反应使用从
硫酰氯、亚
硫酰氯和
氯磺酸组成的组中选出的含
氯化合物与 R2NR'ONa 作为反应物,其中 R 和 R'如上文所定义。 得到的双醚可用作生产聚
氨酯,特别是蜂窝聚
氨酯的催化剂。
