Abstract
AbstractOptimization of the two‐step reaction for preparation of polygly‐cerol esters of fatty acids from the industrial point of view has been studied. Parameters such as nature of the alkaline catalyst, tempera‐ture and time of the reaction have been examined. It was found that the polymerization process needs 260–280 C in the presence of inert gas and 2.5 mol % of NaOH as catalyst. The esterification can be accomplished in the absence of additional catalyst and temperatures as low as 230 C. A simulation model of a chemical plant has been used for evaluation of cost of the production of such emulsifiers.
