Tributyl citrate is a new,green,non-toxic and environmentally friendly plasticizer,which is considered as a substitute for the traditional non-environmentally friendly and toxic plasticizer-phthalate ester,and has been widely used in polymer materials and petrochemical industry.In this paper,the synthesis of tributyl citrate catalyzed by solid acid in recent years is reviewed.The involved acid catalysts include solid superacid,acidic molecular sieves,solidified heteropolyacids,carbon-based solid acid and ionic liquid,and their catalytic properties and catalytic mechanism are summarized.Solid acid overcomes the defects of traditional liquid acid,such as strong corrosion,difficult separation and complex post-treatment.The development direction and prospect of solid acid catalyst are also prospected.
