AI Technical Summary
Existing sodium sarcosinate production processes suffer from insufficient safety, poor controllability, high raw material risks, and difficulty in large-scale, efficient production.
A three-stage series falling film reactor and a microchannel reactor are used for continuous flow reaction. Combined with a distributed control system and a safety instrument system, the cyanation and amination reactions are continuous and precisely controlled. Risks are reduced by using low-concentration raw materials and safety interlocking measures. In the hydrolysis step, alkali solution is added dropwise to buffer the exothermic reaction.
It has achieved efficient, safe and stable production of sodium sarcosinate, with a yield consistently above 96% and high batch consistency, making it suitable for large-scale industrial applications.
