Abstract: The present invention is directed to a basic ionic liquid treatment for removing chloropropanol and/or glycidol, or their fatty acid esters, from glyceride oil, as well as a process for refining glyceride oil which includes the basic ionic liquid treatment. The present invention also relates to uses of the basic ionic liquid and glyceride oil compositions obtained from the ionic liquid treatment.

Abstract: The present invention relates to a process for refining glyceride oil comprising the steps of: (i) contacting glyceride oil with a liquid comprising a basic quaternary ammonium salt to form a treated glyceride oil; wherein the quaternary ammonium salt comprises a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and a quaternary ammonium cation; (ii) separating the treated glyceride oil from a salt comprising the quaternary ammonium cation; and (iii) subjecting the treated glyceride oil after the separation step to at least one further refining step; and to the use of contacting a glyceride oil with the basic quaternary ammonium salt for preventing or reducing the formation of fatty acid esters of chloropropanols and/or glycidol upon heating of the glyceride oil.

Abstract: The present invention relates to a process for removing metal from metal-containing glyceride oil comprising the steps of: (i) contacting a glyceride oil, comprising chromium, manganese, iron, cobalt, nickel and/or copper in a total amount of from 10 mg/kg to 10,000 mg/kg, with a liquid comprising a basic quaternary ammonium salt to form a treated glyceride oil; wherein the basic quaternary ammonium salt comprises a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and (ii) separating the treated glyceride oil from a salt comprising the quaternary ammonium cation, providing a treated glyceride oil containing a reduced amount of metals.

Abstract: In a method of absorbing CO2 from a gas mixture the use of an absorption medium comprising water and at least one amine of formula (I) where R1 is a —(CH2)n—(XCH2CH2)m—Y—R3 radical where R3=hydrogen or an alkyl radical having from 1 to 6 carbon atoms, X and Y are each, independently of one another, NR3, oxygen, SO or SO2, where in the case of Y?SO and in the case of Y?SO2, R3 is not hydrogen, and Y—R3 can be an N-morpholinyl radical or an N-piperazyl radical, n=2 to 4, m=0 to 4 and R2 is hydrogen, an alkyl radical having from 1 to 6 carbon atoms or a radical R1, where m is not 0 when R2 is not a radical R1, Y?NR3 and Y—R3 is not an N-morpholinyl radical and not an N-piperazyl radical, makes it possible to avoid precipitation of a solid during the absorption of CO2 and a separation into two liquid phases during the regeneration of the absorption medium.

Abstract: CO2 is absorbed from a gas mixture by contacting the gas mixture with an absorption medium which comprises at least water as solvent and at least one amine of formula (I) where R1 is an aliphatic radical, having 2 to 6 carbon atoms and at least one amino group, and R2 is hydrogen, a C1-4 alkyl radical or a radical R1.
