Abstract
The invention relates to a method for the basic or acidic catalyzed esterification and transesterification of fatty acids, such as oils and fats, i.e. the esters of glycerin with fatty acids, by dispersion of low alcohols, especially methyl alcohol, in the liquidic initial product. The invention is characterized in that the methyl alcohol (or other low alcohols) is fully dispersed in the reaction mixture. The invention also relates to embodiments of said method.
Claims14
A method for esterifying a fatty acid, an oil, or a fat, the method comprising:
- introducing a liquid raw material to a dispersion machine, said liquid raw material selected from the group consisting of fatty acids, oils, fats, and combinations thereof, said liquid raw material further comprising a catalyst selected from the group consisting of an acid catalyst and a base catalyst;
- and
- dispersing a short chain alcohol in said liquid raw material to form a dispersion, said dispersion having a globule size between about 1 μm and 50 μm.
A method for transesterifying a fatty acid, an oil, or a fat, the method comprising:

- and
- dispersing a short chain alcohol in said liquid raw material to form a dispersion, said dispersion having a globule size between about 1 μm and 50 μm.
