羟基脂肪酸从源油的回收和纯化
摘要：
本发明涉及从源油回收、纯化和富集羟基脂肪酸的方法。所述方法包括以下步骤：(a)甲基化所述源油，以在其中形成羟基脂肪酸甲酯和非羟基脂肪酸甲酯；(b)用包含戊烷/己烷和短链醇的有机溶剂混合物将羟基脂肪酸甲酯与非羟基脂肪酸甲酯分离；和(c)从所述有机溶剂混合物分别回收羟基脂肪酸甲酯和非羟基脂肪酸甲酯。可用所述方法回收、纯化和富集的羟基脂肪酸包括蓖麻油酸、12-羟基-顺-9，15-十八碳二烯酸(densipolic acid)、14-羟基-11-二十碳烯酸(lesquerolic acid)和14-羟基-11，17-二十碳二烯酸(auricolic acid)。可将所述非羟基脂肪酸甲酯回收、纯化和进一步加工成生物柴油燃料和/或润滑剂。
摘要（英）：

A process for recovering, purifying and enriching hydroxy fatty acids from source oils. The process comprises the steps of: (a) methylating the source oil to form therein hydroxy fatty acid methyl esters and non-hydroxy fatty acid methyl esters; (b) separating the hydroxy fatty acid methyl esters from the non-hydroxy fatty acid methyl esters with an organic solvent mixture comprising a pentane/hexane and a short-chain alcohol; and (c) separately recovering the hydroxy fatty acid methyl esters and the non-hydroxy fatty acid methyl esters from the organic solvent mixture. Hydroxy fatty acids that can be recovered, purified and enriched with the process include ricinoleic acid, densipolic acid, lesquerolic acid, and auricolic acid. The non- hydroxy fatty acid methyl esters can be recovered, purified and further processed into biodiesel fuels and/or lubricants.
