Abstract:
The invention relates to a process for the preparation of a mixture of branched and oligomeric fatty acids, by contacting a composition comprising unsaturated straight chain fatty acids with an ionic liquid.
Abstract:
A process for making a polyamide polymer, said process comprising heating, in one or more ionic liquid(s), one or more polyamide precursor(s) selected from: (i) one or more free dicarboxylic acid(s) or ester(s) thereof, with one or more diamine(s); or (ii) one or more salt(s) of a dicarboxylic acid with a diamine; or (iii) one or more lactam(s); or (iv) mixtures of any of the foregoing precursors (i) to (iii).
Abstract:
Disclosed herein are ionic liquid compositions comprising active pharmaceutical, biological, and nutritional compounds, and methods of use. Further disclosed are compositions of matter including liquid ion pairs alone or in solution and their use; compositions of ionic liquids that are 'solvated,' for example, 'hydrated' and their uses.
Abstract:
The invention relates to a process for the branching of fatty acids or derivatives thereof. More in particular, the invention provides a method for branching saturated fatty acids. This is achieved by contacting a source comprising fatty acids or derivatives thereof, with an ionic liquid. The invention also relates to the mixture of branched fatty acids so obtained.
Abstract:
The invention relates to an ionic liquid composition and a method for preparing the ionic liquid. The ionic liquid comprises a cation containing the Formula I , disclosed, and wherein: n is 1 or 2, R 1 is selected from the group consisting of: H, C 1 - C 12 alkyl, aryl or together with R 2 may form a heterocyclic ring, and R 2 is selected from the group consisting of: H, C 1 - C 12 alkyl, aryl or together with R 1 may form a heterocyclic ring, and R 3 is selected from the group consisting of hydrogen and C 1 -C 12 alkyl, wherein if n is 1, then R 3 is C 1 -C 12 alkyl; and wherein R 1 and R 2 are not simultaneously selected from hydrogen. The method for the preparation of the ionic liquid composition provided herein starts with at least one N-substitution of the compound of Formula II , as herein disclosed, and wherein: n is 1 or 2, R 3 is selected from the group consisting of hydrogen and C 1 -C 12 alkyl, wherein if n is 1, then R 3 is C 1 -C 12 alkyl. Further provided is a use of the ionic liquid in a chemical method including at least a method for electro-chemical oxidation.
Abstract:
The present invention provides homogeneous mixtures of saturated hydrocarbons and tetrahydrocarbylphosphonium salt ionic liquids. The present invention further provides a process for expelling a hydrocarbon, preferably a saturated hydrocarbon, from a homogeneous mixture comprising the hydrocarbon and a tetrahydrocarbylphosphonium salt ionic liquid, which process comprises adding to the homogeneous mixture sufficient water to cause the hydrocarbon and the phosphonium salt to form separate phases.
