Abstract
A process for producing cyanuric acid by pyrolyzing urea in a solvent in a closed reactor having interior surfaces exposed to a gas zone, the improvement which comprises contacting the interior surfaces of the closed reactor with solvent in the presence of heat to inhibit the formation of solid deposits on the interior reactor surfaces. The process maintains high rates of heat transfer during the reaction period and reduces the frequency and cost of reactor cleaning.
