    摘要: The present invention relates to deacidification of glyceride oils. The present invention provides a process for removing free fatty acids from glyceride oil, preferably palm oil, containing free fatty acids, said process comprising the steps of: (i) contacting the glyceride oil containing free fatty acids with the basic ionic liquid; wherein the basic ionic liquid has a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and a cation selected from: [N(Ra)(Rb)(Rc)(Rd)]+, wherein: Ra, Rb, Rc and Rd are each independently selected from hydrogen, a C1 to C8, straight chain or branched alkyl group or a C3 to C6 cycloalkyl group, wherein said alkyl or cycloalkyl groups are unsubstituted or may be substituted by one to three groups selected from: C1 to C4 alkoxy, C2 to C8 alkoxyalkoxy, C3 to C6 cycloalkyl, —OH, —SH, —CO2(C1 to C6)alkyl, —OC(O)(C1 to C6)alkyl, or any two of Ra, Rb, Rc and Rd combine to form an alkylene chain —(CH2)q— wherein q is from 3 to 6; and (ii) obtaining a treated glyceride oil having a reduced content of free fatty acid compared to the glyceride oil feed of step (i).

    摘要: The present invention relates to a process for the removal of free fatty acids from glyceride oils, especially palm oil. In particular, the present invention is directed to a process wherein specific ionic liquids are utilised for removing free fatty acids contained in glyceride oils, preferably palm oil, such that a glyceride oil, having a reduced content of free fatty acids may be obtained. The invention also relates to treated glyceride oil compositions, preferably treated palm oil compositions, comprising certainionic quids to prevent build-up of free fatty acids in stored oil.
