- A solid acid catalysis of the preparation process of benzoic acid ester plasticizer (by machine translation)
-
The present invention discloses a solid acidify catalytic benzoic acid ester plasticizer of the preparation process, the preparation method is: to benzoic acid and alcohol as the raw material, with agent and catalyst in direct reaction to produce benzoic acid ester compound; catalytic system of the invention compared with the sulfuric acid, toluene sulfonic acid and sulfuric acid to sodium has a better catalytic activity, so the catalyst less consumption, in addition, because of the use of the is supported on a solid acid catalyst, after the reaction directly filtering can realize the separation of the catalyst, and the catalyst can be reused, makes the production process more simple, and can be basically prevent the generation of waste water, makes the production process more green environmental protection.
