Hydrogen was injected thereinto under an initial pressure of 100 kg/cm2G and reaction was effected at 100° C. to cause absorption of 0.59 mole of hydrogen for 35 minutes. The catalyst was filtered off and the solvent was distilled out. Then, distillation under reduced pressure was effected to obtain 12.8 g of colorless crystal of 1,3,5-tris(aminomethyl) benzene (MTA). The product had a melting point of 49° to 51° C. and a boiling point of 136° to 139° C./0.4 mmHg.
