摘要： The invention concerns a method for producing fatty acid esters from fatty acid triglyceride and in particular from animal or vegetable fats and oils by transesterification with a monovalent low-molecular weight alcohol in the presence of a homogeneous or heterogeneous catalyst. In accordance with the invention, the formed fatty acid ester is extracted from the reaction mixture by means of a near-critical extractant. In this way fatty acid esters are obtained at high yield and excellent purity. As the extractant preferably a low pressure gas having a reduced temperature at 20° C. of about 0.7, preferably of equal to or greater than 0.7, is employed. Preferred extractants are carbon dioxide, propane, butane, dimethyl ether, ethyl acetate or mixtures thereof.

摘要： A method for removing free fatty acids from fats or oils of biological origin or their steam distillates by extracting the free fatty acids with a mixture of basic organic nitrogen compounds and water as an extraction medium at a temperature below the boiling point of the organic nitrogen compounds. The content of the basic organic nitrogen compounds in the extraction medium is 20-30% by weight. In this manner, the formation of a viscous soapstock which is difficult to remove is prevented. The boiling point of the basic organic nitrogen compounds used is the same as or above boiling point of water and below the boiling point of the fatty acids to be extracted in order to enable simple recovery of the extraction medium.

摘要： The present invention relates to a process for obtaining fatty acid esters from triglycerides by means of alcoholysis. In particular, the invention relates to a process for the transesterification of fat and/or oil by alcoholysis wherein, in order to accelerate the process in the initial stage, at least one alkanol fatty acid ester is added in a quantity such that the reaction mixture produced thereby consists of one phase. A high reaction rate can thereby be maintained in the process from the beginning.
