摘要：
A process for removing chloropropanol and/or glycidol, or their fatty acid esters, from glyceride oil comprising contacting the glyceride oil with a basic ionic liquid comprising an organic quaternary ammonium cation, and separating the treated glyceride oil from an ionic compound comprising the organic quaternary ammonium cation. The basic anion of the basic ionic liquid is selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate. Preferably the basic ionic liquid is selected from choline bicarbonate or choline hydroxide, and the process further comprises subjecting the glyceride oil to at least one refining step before and/or after contacting the glyceride oil with the basic ionic liquid. Also claimed is the use of the basic ionic liquid for removing chloropropanol or glycidol from glyceride oil. Claims to compositions comprising glyceride oil and a basic ionic liquid are also included.
