Abstract (en)

[origin: DE19819655A1] The invention relates to a method for producing fatty acid esters with an acid value of less than 1 and an OH value of less than 15. According to said method, triglycerides of native origin are reacted in the presence of a monovalent fatty alcohol with 10 to 24 C-atoms or a corresponding ethoxylate or propoxylate and a catalyst, at temperatures of 180 to 240 DEG C and at a pressure of 100 to 0.01 kPa. The glycerol formed during the reaction is removed by distillation through pressure reduction and the optionally separated fatty alcohol is recycled.
