|Applicants:||SHIJIAZHUANG SAN TAI CHEMICAL CO., LTD
|Title:||METHOD FOR PREPARING 1,3,6-HEXANETRICARBONITRILE|
Provided is a method for preparing 1,3,6-hexanetricarbonitrile, comprising the following steps: A. preparation of 1,6-dicyano-2-butylene; and B. preparation of the 1,3,6-hexanetricarbonitrile. Provided is a new method for preparing 1,3,6-hexanetricarbonitrile. In addition to being a preparation method which is completely different from a traditional process, the preparation method also overcomes the safety problem present in the preparation of the 1,3,6-hexanetricarbonitrile in the presence of sodium, thus enabling the process to be safer, and at the same time, also achieving the requirements of large-scale industrial production. In addition, the preparation method of the present invention also has the advantages such as a high yield, easily available raw materials, a simple reaction control, and a high product purity.
