【摘要】 油茶籽油中油酸含量丰富。本文以油茶籽油为出发物料,对油酸溶剂法分离及尿素包合法纯化工艺进行了研究。结果表明,以95%甲醇为分离溶剂,95%甲醇与混合脂肪酸重量比为4:1,在-10℃保存60min时,饱和脂肪酸除杂率为50%,油酸的纯度为86%,油酸回收率为91%;以90%甲醇为包合溶剂,尿素与脂肪酸重量比为4:1,脂肪酸浓度为10%,在4℃中保存16h后,油酸纯度可提高到92%,回收率可达83%。更多还原

【Abstract】 The Camellia -oleifera Abel Oil contains high content of oleic acid.. The separation and purification of oleic acid from Camellia-oleifera Abel Oil by Solvent-separation and Urea adduction fractionation was studied. Solvent-separation conditions were optimal. Under optimal conditions,the recovery of oleic acid was 91%,the impurity of Saturated Fatty Acids was 50% at a fattyacid-to-95% MeOH(w/w)of 25%,a crystallization temperature of-10℃ and crystallization time of 60 min. The recovery of oleic acid was 83%,the purity of oleic acids was 92% at a fatty acid-to-90% MeOH(w/w)of 10%,a urea-to-fatty acid of 4:1,a crystallization temperature of 4℃ and crystallization time of 16h.更多还原
