Abstract

The carbamide is heated to about 150 deg. C, when the following is added (wt. %): a catalyst, either 0.1-1.0 CaCO3, or 0.25-2.5 dolomite and 0.001-0.1 active charcoal. The mixt. is then heated to 180 deg. C for 30 minutes. The obtd. partly polymerised carbamide is treated with either sulphuric, phosphoric, nitrous or an organic acid (1-40 wt. % in soln., or 2-10 wt. % solids) at 85-100 deg. C. The product is ground and mixed with a bulk material.
