Abstract
PURPOSE: To obtain the title compound in simple procedures in high yield, by heating a homogeneous mixture of powdered cyanuric acid free from moisture and a heating medium solid granular material, and by reacting the mixture with hydrogen chloride in another reactor to coagulate and separate a by-product.
CONSTITUTION: Powdered cyanuric acid, homogeneously mixed with a heating medium solid granular material, e.g. silica gel or sand, under substantially anhydrous conditions, is heated to 300°C or above. The isocyanic acid thus formed is reacted with hydrogen chloride in another reactor packed with a heat-resistant inert solid material, e.g. asbestos or glass wool, at 400°C or above, to give a gas reaction mixture, which is passed through a zone heated at 100W250°C. The ammonium chloride formed as a by-product is coagulated, separated, and then passed through the next cooling zone, to give corbamyl chloride.
USE: Carbamyl group introducing agents for various organic compounds.
