IONIC LIQUID CONTAINING PHOSPHONIUM CATION HAVING P-N BOND AND METHOD FOR PRODUCING SAME

An ionic liquid which contains an organic matter represented by the following general formula (1) as a cation component. The ionic liquid is stably in a liquid state over a wide temperature range and is excellent in electrochemical stability. The ionic liquid is advantageously used for applications such as electric power storage devices, lithium secondary batteries, electrical double layer capacitors, dye-sensitized solar cells, fuel cells, and reaction solvents.

Aminophosphonium compounds

The present invention relates to compounds of the formula in which one, two or three of the radicals R1, R2, R3and R4are where m and n are an integer from 1 to 10, R5, R6, R7and R8are, independently of one another, identical or different and are a straight-chain or branched alkyl radical having 1 to 10 carbon atoms, and the remaining radical(s) R1to R4are or —NR9R10, where R9and R10are identical or different and are a straight-chain or branched alkyl radical having 1 to 10 carbon atoms, and X?is an inorganic or organic anion or an equivalent of a multiply charged inorganic or organic anion. The invention further relates to mixtures of substances comprising compounds of the formula (1), to a process for preparing the compounds of the formula (1) and to the use thereof.

Catalyst recovery for halogen exchange reactions

It has been found possible to separate catalytically-active aminophosphonium catalysts from mixtures composed predominately of aminophosphonium catalyst residue(s) and heavy ends from a halogen exchange reaction conducted in an aprotic solvent/diluent by extracting such mixtures with a neutral or acidic aqueous extraction solvent medium. Various ways of isolating from the halogen exchange reaction product mixture a mixture composed predominately of aminophosphonium catalyst residue(s) and heavy ends are described. Halogen exchange processes in which the catalytically-active aminophosphonium catalysts are separated for reuse are also described. Since aminophosphonium catalysts are expensive, the present process technology fulfills a need which has existed for an effective way of recovering such catalysts in catalytically active form enabling reuse of such materials, especially as halogen exchange catalysts.
