Study on the reaction mechanism of liquefaction of bamboo chips catalyzed by solid phosphoric acid
In this paper,the biobased polyols were prepared by liquefaction of bamboo chips with solid phosphoric acid as catalyst,and then the components of the liquefaction products were characterized by FT-IR,GC-MS,NMR and other techniques to study the reaction mechanism.The results show that the formation of Vinyl ethyl carbitol and other alkenes was mainly formed by the dehydroxylation of one end of PEG400 catalyzed by solid phosphoric acid,while substances such as glutaric acid were mainly formed by the reoxidation of biomass such as cellulose catalyzed by solid phosphoric acid.In addition,solid phosphoric acid also solved the problem of high acid value in liquefaction products.
