Reaction Steps
A mixture of 14.2 grams of N-n-octyl-N'-(2-phenyl-2-propyl)-thiourea, 20 grams of basic lead carbonate and 100 ml of dry xylene was heated under reflux for 3 hours. The reaction liquid was then separated by filtration followed by concentration of the mother liquor, whereupon N-n-octyl-N'-(2-phenyl-2-propyl)carbodiimide of high purity was obtained. When this was distilled further, 10.1 grams of the intended product of b.p. 121°-3° C./0.15 mmHg was obtained as a pure product.
