1,3,5-Tris(aminomethyl)benzene(I) was prepd. by hydrogenation of 1,3,5-trocyanobenzene(II). Thus, a mixt. of 15g II and 15g Raney Ni-Cr in MeOH-m-xylene was heated at 100oC and 100kg/cm2 H to goive 12.8g I, which (30g) was hydrogenated over 3g 5% Ru-Al2O3 at 115oC and 120 kg/cm2 H to give 26.8g 1,3,5-tris(aminomethyl)cyclohexane. CO2 was introduced to 90g I followed by COCl2 at 10-130oC to give 1,3,5-tris(isocyanatemethyl)benzene, which was formulated in a coating compn.
