| titleOfInvention | Method for continuously synthesizing pyridinium salt of hydroxypropane sulfonate |
| abstract | The invention discloses a method for continuously synthesizing pyridinium salt of hydroxypropane sulfonate, which comprises the steps of adding a phase transfer catalyst and sodium sulfite to an alkali metal hydrogensulfite or pyrosulfite solution to obtain HSO 3 - Mixing liquid, the mixed liquid and epichlorohydrin are simultaneously introduced into the first reactor to cause a ring-opening reaction; a mixture of pyridine and a catalyst, and a ring-opening reaction product simultaneously enter the second reactor, and the reaction product is obtained. . The method of the invention changes the mixing order and the order of addition of the raw materials, so that the raw materials to be involved in the reaction enter the reactor at the same time to participate in the corresponding reaction, effectively reducing the occurrence of side reactions, improving the selectivity and conversion rate of the reaction, and thereby improving The yield and purity of the product can meet the needs of high-end customers in the electroplating industry; compared with the batch operation of the conventional process, the method of the invention shortens the reaction time, improves the production efficiency, and is more suitable for industrial production. |
