Yacoo has been licensed its patent "a preparation method of 1,3,6- hexanetricarbonitrile"

25 August 2017
  Recently, our company (Suzhou Yacoo Science Co., Ltd.) has received authorization for the invention patent "a preparation method of 1,3,6- hexanetricarbonitrile", patent number ZL 2014 1 0625910.9.
  1,3,6-hexanetricarbonitrile is mainly used as organic synthesis intermediates, high boiling solvents, and electrolyte additives. Especially in the application of high-voltage lithium-ion battery electrolyte, it has a huge advantage in high temperature storage and recycling performance, but its synthesis technology and supply has been the big problems. There are two main synthetic processes: one is to produce 1,3,6-hexanetricarbonitrile in the process of producing adiponitrile or using intermediate of adiponitrile as the starting material; the other is to use 2-Amino-1-cyclopentene-1-carbonitrile and acrylonitrile in the presence of sodium to obtain the product. None of the above methods can achieve large-scale industrial production. The preparation method according to the invention not only overcomes the safety problem under the condition of sodium existence, realizes the demand of large-scale industrial production, but also has the advantages of high yield, high product purity and low chromacity.
  Suzhou Yacoo Science Co., Ltd. is a national high-tech enterprise with research, production, distribution and service. Over the years, the company has been focusing on scientific and technological innovation, and encouraging staffs to study to solve practical problems. The acquisition of this patent not only proves the company's technological level, effectively enhances the market competitiveness of the enterprise, but also make a tremendous contribution to the development of the whole industry.
