Based on experimental data, the article shows the possibility of using free fatty acids contained in cotton soapstock, mainly acids with carbon atom C16—C18 for their esterification with butyl alcohol and the production of esters. In laboratory conditions, esters obtained on the basis of linoleic and oleic acids, as well as butyl alcohol, were tested for depressive activity to reduce the freezing point of highly paraffinic oils.
