| titleOfInvention | A gas-liquid microsulfonation system and method for synthesizing anionic surfactants |
| abstract | The invention discloses a gas-liquid micro-sulfonation system and method for synthesizing anionic surfactants. The gas-liquid micro-sulfonation system comprises a gas - phase SO3 generation and pumping unit, a liquid-phase raw material pumping unit, and a micro-reaction unit and product collection and exhaust gas treatment units. The present invention uses gas - phase SO3 as a sulfonating agent to efficiently synthesize anionic surfactants in a micro-reactor. Compared with the liquid-liquid micro-sulfonation technology, the micro-reactor proposed by the present invention has faster gas-phase and liquid-phase flow rates. , which can realize the rapid mass transfer of gas-liquid two-phase and the rapid removal of reaction heat, and has higher product quality. In the gas-liquid micro-sulfonation system, the content of linear alkyl benzene sulfonic acid synthesized with gas-phase SO 3 as sulfonating agent can reach 99.17%. At the same time, the separation of organic solvent in the product is avoided, and the aging step is omitted. The process steps are greatly simplified and the reaction time is shortened. |
