Abstract: The present disclosure relates to a catalyst for synthesizing a cyclic carbonate and a synthesis method for a cyclic carbonate. The present disclosure provides a novel catalyst of a hydroxy quaternary phosphonium salt structure, wherein a specific type of substituent is selected, such that the catalytic effect of the catalyst is significantly improved, and meanwhile, the catalyst has superior stability. For the cyclic carbonate synthesized by using the catalyst of the present disclosure, the selectivity of the product is as high as 99.8%, and the yield is as high as 99%; the catalyst can still maintain a relatively high yield and relatively good stability after being repeatedly used.
