| titleOfInvention | Lignin-based solid acid catalytic benzylation reaction method |
| abstract | The invention relates to a method for catalyzing Friedel-Crafts benzylation reaction of a benzene ring compound by lignin-based solid acid, in particular to a strong benzylation reaction obtained by carbonizing and sulfonating sodium lignosulfonate A method for catalyzing clean benzylation reaction of benzene ring compounds and benzyl alcohol by using acidic solid acid as a catalyst belongs to the technical field of fine chemical preparation. The invention utilizes the derivatization product sodium lignin sulfonate of the paper industry byproduct black liquor as the raw material to prepare the strong lignin sulfonate through carbonization and sulfonation treatment The acidic lignin-based solid acid catalyst can efficiently catalyze the clean benzylation reaction of benzene ring compounds such as benzene, toluene, p-xylene, m-xylene, o-xylene, mesitylene, nitrobenzene or chlorobenzene and benzyl alcohol. The method has simple reaction process, and makes full use of industrial byproductThe catalyst has low cost, high catalytic activity, high water resistance and good recycling performance, and provides a new efficient and environment-friendly way for the benzylation reaction of the benzyl alcohol route. |
