PROCESS FOR THE PREPARATION OF ALKYLENE BIS (2-OXAZOLINES)

摘要

The invention relates to a process for the preparation of a bis(cyclic imino ether) by converting an aliphatic 1,2-dinitrile with an amino alcohol into the corresponding 1,2-alkylene-bis(cyclic imino ether) while being heated. The conversion takes place at a temperature between 50-190 DEG C, preferably in the absence of a catalyst. Preferably, the reaction product, which may be obtained in the form of an imino azacyclopentane polyol, is separated and upgraded in a way known per se before this intermediate product is converted into the corresponding 1,2-bis(cyclic imino ether) while being heated further.
