【摘要】 以油脚为原料，经皂化、盐析、酸化、水洗制成混合脂肪酸。将此混合脂肪酸减压蒸馏，同时用低温水冷却，使芥酸凝聚与其他液体酸分离，从而制得纯度较高的工业品芥酸更多还原

【Abstract】 By Oil sediments as raw material,through being saponified,salted out,acidized and washed with water,it can be made into mixted fatty acid,then the mixted fatty acid is distilled by being decreased in pressure and cooled with cold water.The erucic acid is condensed and separated from other liquid fatty acids.Thus,a industrial erucic acid of higher purity can be got.更多还原
