    Abstract: The present invention relates to a process for the work-up of acidic or basic ionic liquids (IL) of the general formula (I), [A]+(1/n)*[Y]−  (I) where [A]+ is a quaternary ammonium cation and (1/n)*[Y]n− is one anion equivalent of an n-fold charged anion, which comprises adding a conjugate acid-base pair selected from among compounds of the formula (II), [A]+[X]−  (II) where [A]+ has the meaning given for the ionic liquid and [X]− is a conjugate base to the ionic liquid (IL).

    Abstract: A process for the preparation of acylphosphines of formula (I) wherein m is 1 or 2; R1, R2, and R3 are organic residues derived from aliphatic or aromatic hydrocarbons; by (1) reacting organic phosphorus halides of formula (II) wherein Y is Br or Cl,with an alkali metal in a solvent in the presence of an activator, wherein the alkali metal is present in the form of a dispersion of alkali metal particles having a mean particle size of ≤ 500 µm in the solvent, (2) subsequent reaction with acid halides of formula (III) which process is carried out without isolation of the intermediates. Preferably, R1, R2 and R3 are independently from each other phenyl, naphthyl and bi-phenyl, being unsubstituted or substituted by one to five halogen, C1-C8 alky and/or C1-C8 alkoxy. Most preferably, R1 and R3 are phenyl and R2 is 2,4,6-trimethylphenyl. The alkali metal is preferably sodium, the activator is preferably chlorobenzene and/or n-butanol.

    CPC classification number: C07C51/58 ,  C07C63/04

    Abstract: The invention relates to a method for producing arylcarboxylic acid chlorides (I) substituted at least once by aryl (C1-C20) and/or halogen consisting, at a first stage thereof, in reacting an aromatic compound (II) substituted at least once by alkyl (C1-C20) and/or halogen with CCl4 in the presence of a Friedel-craft catalyst in such a way that corresponding trichlormethylated aromatic compounds (III) at least once substituted by aryl (C1-C20) and/or halogen are obtainable. At a second stage, the trichlormethylated aromatic compound (III) is treated with water or a proton acid in the presence of a catalyst, whereby making it possible to obtain an arylcarboxylic acid chloride (I). In the preferred embodiment, said trichlormethylated aromatic compound (III) is not isolated in the form of an intermediate product and, at the second stage used dissolved in the solvent of the first stage.
