Research progress on catalytic synthesis of butyraldehyde 1,2-propanediol acetal
The experimental results of synthesis of butyraldehyde 1,2-propanediol acetal in the presence of 13 kinds of catalysts such as FeCl 3 ·6H 2 O, Fe 2 (SO 4 ) 3 · x H 2 O, NH 4 Fe(SO 4 ) 2 , SnO, CuSO 4 , PVC-SO 3 H,polyvinyl chloride ferric chloride(PVC-FeCl 3 ), macroporous ion exchange resin, Vitamin C, solid super acid SO 2- 4 /TiO 2 , tungsten silicic acid, TiSiW 12 O 40 /TiO 2 and HY-type molecular sieve etc are reviewed. The results show that CuSO 4 , PVC-SO 3 H,polyvinyl chloride ferric chloride(PVC-FeCl 3 ), macroporous ion exchange resin, and TiSiW 12 O 40 /TiO 2 are excellent catalysts to synthesize butyraldehyde 1,2-propanediol acetal with high yield.
