Kinetic Study of Sodium Cocoyl Sarcosinate Synthesis and Factors Affecting the Reaction on Bench and Pilot Scales

摘要

Sodium cocoyl sarcosinate is an important surfactant with a particular chemical structure and many practical applications in various industries. The synthesis of sodium cocoyl sarcosinate involves the reaction of cocoyl chloride and N-methyl glycine. The influences of reactant molar ratios, temperature, reaction time, pH, and solvent on the reaction yield were investigated and also the kinetics of the reaction was studied. It was found,that the reaction follows second order kinetics and the reaction rate constant is 0.0153 mol~(-1) L s~(-1) at 35 °C. Also production of sodium cocoyl sarcosinate was carried out at bench and pilot scales which is described in details.
