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

Abstract

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.

Adsorption of Cr(VI) ions from aqueous systems using thermally sodium organo-bentonite biopolymer composite (TSOBC): response surface methodology, isotherm, kinetic and thermodynamic studies

“…In this study, the most popular kinetic models such as pseudo-first-order and pseudo-second-order were applied for analysis of adsorption data. Generally, the linear form of pseudo-first-model is expressed as follows [54,[67][68][69]:…”

New aspects of lipopeptide-incorporated nanoparticle synthesis and recent advancements in biomedical and environmental sciences: a review

“…20 Surfactants are predominantly used in detergents, wetting agents, emulsifiers, foaming agents, and dispersants, as well as in the food, cosmetics, and petroleum industries. 21,22 There are two types of surfactants projected as biosurfactant and chemical-surfactant, where the biosurfactant (e.g. plant, bacteria, fungi, algae, etc.)…”
