The present article analyses the state of the problem and presents experimental research for the choice of principal method and main parameters of the process of oxy-ethylation of fatty acids of gossypol resin with a view to obtaining demulsifiers for deliquefaction in the system of skimming and treatment of oil. It was established that the lumped reaction of condensation of ethylene oxide with fatty acids proceeds with formation of an intermediate complex. Such a reaction may take place without a catalyst, during an acid or base (nucleophilic) catalysis. During a base catalysis, the first stage of addition is clearly separated from subsequent ones; the first intermediate product can be obtained with the yield approaching 100%. It is only after the exhaustion of the original substance that subsequent ethylene oxide adducts are formed.



It was ascertained that the makeup of the total co-product does not depend on the structure of reactor or the conditions of synthesis. It is only its yield that changes. On the basis of experimental data we selected and defined the datum values of the main variables of the process of oxy-ethylation which were then objectified for every option of the instrument and technological execution of the procedure.
