Procedure

Sixty grams fumed silica (sold as "Cab-O-Sil" MS-7 by Cabot Corp.) were agitated in a 1-liter flat bottom reaction kettle under a carbon dioxide atmosphere. The kettle was fitted with a stirrer, a gas inlet and an inlet from a pump. 1,2-Diaminopropane and carbon dioxide were simultaneously added via the pump and gas inlets over a period of 7.5 hrs. while the temperature was kept at 25°-30° C. At the end of this time 211 g. of 1,2-diaminopropane carbamate had been formed.
