| Abstract: | s:It was used four group catalyst system which the ratio is different for Redutive Cleavage of permthylated pullulan.The products of Reductive Cleavage was analysted and tested by GCand NMR. The results show that the four group catalyst system for the Reductive Cleavage of permethylated pullulan could be use and were obtained expect products.The yiled of main products demostracted that the one consisting of mixture of Et3 SiH:TMSOMS:BE3 OEt=5:5:1 was the best and the structure of pullulan was determined. |
