Reaction Steps

A 1,000 ml three-neck, round bottom flask was charged with 178 grams (1 mole) of a mixture consisting of 80 parts by weight 5-tertiary butyl-2,4-toluenediamine and 20 parts of a 3-tertiary-butyl-2,6-toluenediamine mixture. The tertiary-butyl-toluenediamine was prepared by reacting an 80:20 toluenediamine commercial mix with isobutylene in the presence of an H-Y zeolite catalyst. After charging the tertiarybutyl-toluenediamine to the flask, 176 grams (2 moles) of ethylene carbonate were charged to the vessel and the contents stirred. The ethylene carbonate dissolved readily in the tertiary-butyl-toluenediamine and a clear amber solution resulted. The contents were heated to a temperature of about 150° C. and at such time carbon dioxide evolution appeared. Heating was continued until a temperature reached about 260° C. during which time carbon dioxide gas evolution ceased. Approximately 1.7 cubic feet or 2.2 moles of carbon dioxide recovered from the vessel.
