Latest Patents

Gran Martinez Alejandro holds a patent for a method for producing trans-bis(aminomethyl)cyclohexane, as well as bis(isocyanatomethyl)cyclohexane, polyisocyanate composition, and polyurethane resin. The patented method involves a trans-isomerization step where cis-dicyanocyclohexane is isomerized into trans-dicyanocyclohexane. This is achieved by heating dicyanocyclohexane containing cis-dicyanocyclohexane in the presence of a tar component produced by distillation. Following this, an aminomethylation step allows the trans-dicyanocyclohexane to contact with hydrogen, resulting in the production of trans-bis(aminomethyl)cyclohexane. This innovative approach enhances the efficiency and effectiveness of producing these important chemical compounds.
