| titleOfInvention | Method for continuously preparing sulfonated product of benzene series by using micro-reaction device |
| abstract | The invention discloses a method for continuously preparing a sulfonated product of a benzene series by using a micro-reaction device, which comprises the following steps: (1) adding SO 3 Mixing the gas and air to obtain mixed gas; (2) respectively pumping the liquid benzene series and the mixed gas into a microreactor in a microreactor to carry out sulfonation reaction to obtain reaction liquid; (3) cooling the reaction liquid to room temperature, carrying out solid-liquid separation, and collecting solids to obtain a crude product; (4) and (4) dissolving the crude product obtained in the step (3) in water, and removing insoluble substances to obtain the product. The micro-reaction device is used for preparing the benzene series sulfonated product, the reaction condition is milder, the reaction rate can be effectively controlled, the reaction time is shortened, the continuous production is realized, the generation of the by-products of sulfone and benzene disulfonic acid is reduced, the yield can reach 99.1 percent to the maximum, the refining process is simpler, and the product quality is improved; basically has no amplification effect, and is beneficial to industrial amplification. |
