Title:
REACTION SYSTEM AND METHOD FOR PREPARING SODIUM N-METHYLTAURATE
Document Type and Number:
WIPO Patent Application WO/2022/032868
Kind Code:
A1
Abstract:
Disclosed are a reaction system and method for preparing sodium N-methyltaurate. The reaction system comprises: an amination reaction kettle, an amination reaction product from which undergoes a reaction in a tubular reactor and then enters a first gas-liquid separation tank. A micro-interface generator for dispersing and crushing a material into micro-bubbles is provided inside the amination reaction kettle, and a sidewall of the amination reaction kettle is provided with a liquid phase material inlet for introducing sodium hydroxyethylsulfonate and a methylamine inlet. The methylamine inlet is arranged in a manner of allowing a methylamine delivery pipe to pass therethrough. The methylamine delivery pipe enters the amination reaction kettle and is connected to the micro-interface generator for introducing methylamine into the interior of the micro-interface generator. By providing the micro-interface reactor inside the amination reaction kettle, the problem in the prior art of system reaction efficiency being low due to methylamine and sodium hydroxyethylsulfonate not being able to be fully mixed in a reaction kettle is solved.
