【Abstract】 It has been systematically studied that sebacic acid is prepared from castor oil by catalyzing.The effects of catalysts and diluent on the yield of sebacic acid were also investigated.The SnO 2-V 2O 5 was employed as catalyst,and white mineral oil as diluent for the first time,which are not as poisoned as Pb 3O 4 and methyl-phenol.The optimal technical conditions were obtained.更多还原
