METHOD FOR PRODUCING TRANS-BIS(AMINOMETHYL)CYCLOHEXANE, METHOD FOR PRODUCING BIS(ISOCYANATOMETHYL)CYCLOHEXANE, BIS(ISOCYANATOMETHYL)CYCLOHEXANE, POLYISOCYANATE COMPOSITION, AND POLYURETHANE RESIN

摘要

The process for the preparation of trans-bis (aminomethyl) cyclohexane comprises reacting dicyanocyclohexane containing cis-dicyanocyclohexane in the presence of a tar component obtained by distillation of the dicyanocyclohexane A trans isomerization step of isomerizing cis-dicyanocyclohexane to trans-dicyanocyclohexane by heating, and a step of bringing the trans-dicyanocyclohexane obtained by the transisomerization step into contact with hydrogen, (Aminomethyl) cyclohexane. / RTI
