Аннотация

The process of separation of fatty acids intensification from a saponified and neutralized cotton tar mixture's components is considered in this article as the aim of the study. The process is used for their purification from impurities and further use for the synthesis of a nonionic demulsifier - reagent based on them for the oil's preparation in field conditions. It is shown that vacuum fatty acid tars of cotton oil are a valuable raw material for free fatty acid production after appropriate processing. One of the possible and promising options for the extraction of free fatty acids from the saponified fraction is a method based on gasoline processing of a wet mixture of cotton tar components in a rotary-pulsation apparatus. It has been established that the technology of obtaining fatty acids from cotton tar in a rotary-pulsation apparatus using an effective solvent - extraction gasoline is resource-saving The influence of some design parameters of rotary-pulsation apparatus working elements on the degree of extraction was investigated. By means of a multistage experimental-technological work, it was possible to optimize the extraction process and achieve results that make it possible to recommend it for use in industrial conditions for separating fatty acids from associated impurities with the following technological regime in the rotary-pulsation apparatus apparatus: the ratio of the mixture: gasoline - 1: 5; the duration of the extraction is 10 minutes; temperature - 50 - 60 ° C. With this technological mode in a rotary-pulsation apparatus it is possible to extract free fatty acids from tar with a yield of 86-87%.
