FIELD: chemistry. ^ SUBSTANCE: invention relates to composition of fatty acids, which has lubricating ability and is characterised by containing: (1) more than 10% C18;3 of fatty acids, (2) more than 30% C18;2 of fatty acids, (3) less than 35% C18;1 of fatty acids, (4) less than 3% of saturated fatty acids, and (5) more than 90% of unsaturated fatty acids; fatty acids give the composition higher low-temperature stability, temperature of cloudiness of fatty acid composition is lower than -4C. Invention also relates to application of composition of fatty acids for obtaining complex ether of monoalcohol or polyalcohol, and as fuel additive; to improved method of obtaining composition of fatty acids, which includes stage of distilling of untreated tall oil, which contains fatty acids of such type and in such concentration that they can ensure low-temperature stability of the target composition of fatty acids with obtaining composition of fatty acids, containing effective amount of tall oil fatty acids, ensuring low-temperature stability. Also is fuel additive revealed. It contains composition of fatty acids, and fuel, containing fatty-acid additive. Composition of fatty acids contains fatty acids of such type and in such concentrations that are able to ensure low-temperature stability. ^ EFFECT: obtaining composition of fatty acids, which has lubricating ability and ensures low-temperature stability. ^ 31 cl, 1 tbl, 6 ex |
