催化碱解蓖麻油制备癸二酸的研究
STUDY ON THE PREPARATION OF SEBACIC ACID FROM CASTOR OIL BY CATALYTICAL METHOD
【摘要】 以蓖麻油为原料 ,在催化剂作用下碱解裂化制备癸二酸 ,同时得到副产品仲辛醇及甘油 ,探讨了催化剂及稀释剂等对癸二酸产率的影响 ,首次采用SnO2 -V2 O5作为催化剂、液体石蜡为稀释剂 ,消除以前用的催化剂Pb3O4 及稀释剂甲酚有毒的缺陷 ,并得出了最佳工艺条件
【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.
