Title:
MICRO-INTERFACE STRENGTHENING SYSTEM AND METHOD FOR PREPARING SODIUM N-METHYL TAURATE
Document Type and Number:
WIPO Patent Application WO/2022/032869
Kind Code:
A1
Abstract:
Provided are a micro-interface strengthening system and method for preparing sodium N-methyl taurate, comprising an amination reaction kettle. A amination reaction product from the amination reaction kettle enters a first gas-liquid separation tank after reacting by means of a tubular reactor. A side wall of the amination reaction kettle is provided with a raw material inlet. The raw material inlet is provided with a micro-interface generator for dispersing crushed materials into microbubbles. A side wall of the micro-interface generator is provided with a methylamine inlet, and the methylamine inlet is connected to a vaporizer for vaporizing methylamine. By means of providing a micro-interface reactor at the raw material inlet of the amination reaction kettle, the micro-interface strengthening system for preparing sodium N-methyl taurate solves the problem in the prior art in which methylamine and sodium isethionate cannot be fully mixed inside the reaction kettle, which results in low system reaction efficiency.
