摘要：A process for recovering lecithin from oil- and lecithin- containing mixtures,comprising extracting a lecithin/oil mixture with an extractant selected from the groupconsisting of a hydrocarbon having 3 carbon atoms, an unbranched hydrocarbon having 4carbon atoms, a branched hydrocarbon having 4 carbon atoms, and mixtures thereof, at apressure of from 1 to 8 MPa and a temperature of from 20 to 100° C., which conditionsensure liquid phase extraction with the development of two liquid phases, one of which isan oil enriched liquid hydrocarbon phase and the other of which is a lecithin enrichedhydrocarbon phase; separating the two liquid hydrocarbon phases; and recoveringsubstantially lecithin-free oil from the oil-enriched phase and substantially oil-free, purelecithin from the lecithin-enriched phase.
