Kinetics of the process of obtaining calcium cyanamide from lime, carbon dioxide and ammonia

Abstract

Technical solutions have been developed to create a technology for obtaining calcium cyanamide from lime, carbonate anhydride and industrial ammonia. A technological scheme for obtaining nitrogen fertilizer and an effective defoliant, calcium cyanamide, has been developed and optimal technological parameters of the process have been determined. An experimental batch of calcium cyanamide has been produced at an experimental installation. The experiments investigated the effect of changes in the initial composition of one of the gas components of a chemical reaction with the relative constancy of the other component. Experimental studies were carried out by the excess method, in which an excess of ammonia was used in one series of experiments, and an excess of carbon dioxide was used in another
