Latest Patents

Chengge Lv holds a patent for a method dedicated to preparing 3-aminomethyl-3,5,5-trimethyl cyclohexylamine. This innovative method involves several key steps: initially, reacting 3-cyano-3,5,5-trimethyl cyclohexanone with excess primary amines while carefully removing the water produced during this reaction. This step ensures that the intermediate product is effectively converted into imine compounds. Following this, the process incorporates an ammonolysis catalyst along with liquid ammonia to facilitate the ammonolysis reaction of the imine compound, resulting in the formation of 3-cyano-3,5,5-trimethyl cyclohexylimine and primary amine. The final step encompasses hydrogenating the 3-cyano-3,5,5-trimethyl cyclohexylimine in the presence of hydrogen and a hydrogenation catalyst, yielding the desired compound—3-aminomethyl-3,5,5-trimethyl cyclohexylamine. This method notably circumvents the production of unwanted by-products, boosting overall yields compared to previous methods.
