| abstract |
The present invention generally provides a process to produce, isolate, and purify a diamine, including nhexamethylenediamine (HMD), cadaverine, putrescine, ethylenediamine and heptamethylenediamine. nThe invention more particularly relates to a method for culturing a microorganism producing the ndiamine, e.g. HMD, to a method of isolating the diamine from diamine-containing cultures or cultured nmedia. Such diamine products are used to make diamine-containing polymers, including polyamides.nWO 2016/106367 PCT/US2015/067478 n1/26 nCulture Microbial Organism nProduce Diamine Carbonates andloCarbamates nProduce Diamine Free Base nIsolate Diamine nFITG. 1. |
