公开的是一种方法和通过该游离脂肪酸简单地通过（FAME）的脂肪酸烷基酯的水解分裂，特别是脂肪酸甲酯，或可替代地可以从包含在植物和动物来源的脂肪酸的甘油三酯的油和脂肪获得的系统。 根据本发明，将一部分已经产生的游离脂肪酸循环回到反应混合物中，这导致水解反应的自加速。

Disclosed is a method and a system by which free fatty acids simply by hydrolytic splitting of fatty acid alkyl esters, in particular fatty acid methyl ester (FAME), or alternatively can be obtained from oils and fats contained in vegetable and animal origin fatty acid triglycerides. According to the invention this part of the free fatty acid already produced is recycled back into the reaction mixture, resulting in a self-acceleration of the hydrolysis reaction.
