Abstract
Process for the purification of sucrose esters, especially process for the separation of sucrose monoesters and diesters of fatty acids, characterized by dissolving a mixture of such esters in a low aliphatic alcohol, at a temperature of about 40º c, at a temperature of about reflux, cooling the solution thus obtained to temperatures ranging from 0ºC to about 35º c, separating the sucrose diesters from the saturated acids with at least 16 carbon atoms, which precipitate, evaporating the alcohol solution, dissolving the residue in ethyl acetate. Ethyl, cooling the solution thus obtained to around 5-20º c, collecting the monoesters of sucrose, which precipitate, evaporating the solution to dryness, and recovering as residue the sucrose diesters of saturated fatty acids, having a maximum of 14 carbon atoms and the sucrose diesters with unsaturated fatty acids.
