Abstract:
A process which can extract a fatty acid from a triglyceride oil includes (a) contacting a triglyceride oil T 1  made of a fatty acid with an aqueous solution W 1  made of a quaternary ammonium salt and an aliphatic diol having 1 to 8 carbon atoms, where a triglyceride oil phase T 2  and an aqueous phase W 2  are obtained, where T 2  has a reduced content of fatty acids compared to T 1  and W 2  has an increased content of fatty acids compared to W 1 ; and (h) separating the triglyceride oil phase T 2  from the aqueous phase W 2  . The quaternary ammonium salt includes a quaternary ammonium cation and a basic anion selected among hydroxide, alkoxide, alkyl carbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, aspartate, taurinate, and lysinate,

Claim (Index 1):
A process for extracting a fatty acid from a triglyceride oil, the process comprising:\n (a) contacting a triglyceride oil T 1  comprising the fatty acid with an aqueous solution W 1  comprising at least one quaternary ammonium salt and at least one aliphatic diol having 1 to 8 carbon atoms, whereby a triglyceride oil phase T 2  and an aqueous phase W 2  are obtained, wherein T 2  has a reduced content of fatty acid compared to T 1  and W 2  has an increased content of fatty acid compared to W 1 ; and (b) separating the triglyceride oil phase T 2  from the aqueous phase W 2 ; wherein the quaternary ammonium salt comprises at least one quaternary ammonium cation and at least one basic anion selected from the group consisting of hydroxide, alkoxide, alkyl carbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, aspartate, taurinate, and lysinate wherein said quaternary ammonium cation is at least one cation according to the structure\n [N(R a )(R b )(R c )(R d )] + , \n wherein R a , R b , R c  and R d  are each independently a C 1  to C 8  alkyl, and wherein one or more of the radicals R a , R b , R c  and R d  is optionally substituted on one carbon atom by a group selected from the group consisting of: C 1  to C 4  alkoxy, C 2  to C 8  alkoxyalkoxy, C 3  to C 6  cycloalkyl, \u2014OH, \u2014SH, \u2014CO 2 R e , and \u2014OC(O)R e , wherein R 2 =C 1  to C 6  alkyl.
