▎ 摘  要

NOVELTY - Preparation of supported-type ionic liquid catalyst comprises using graphene oxide as carrier, carrying out etherification reaction with epichlorohydrin or epibromohydrin, carrying out alkylation reaction with dialkylamine, and immobilizing with halogenated alkane and quaternary ammonium salt. USE - Method for preparing supported-type ionic liquid catalyst (claimed) used for transesterification of ethylene carbonate and methanol. ADVANTAGE - The catalyst can be recycled, has long service life, good catalytic effect, and no pollution, and greatly reduces cost.
