Abstract: Process for the electrochemical condensation of carboxylic acids by the electrolysis of monocarboxylic acids, half esters of dicarboxylic acids or aminocarboxylic acids in which current densities of more than 10 amp./dm.2 on vibrating electrode pairs are used, and in which the degree of neutralization of the carboxylic acids is kept below 10 percent, said process providing high space-time yields and a reaction product which can be worked up without difficulty.

Abstract: 1507920 Esters BASF AG 18 July 1975 [19 July 1974] 30186/75 Heading C2C [Also in Division C7] In electrochemical manufacture of an aromatic or heterocyclic ester by anodic acyloxylation of an aromatic or heterocyclic compound with an alkanoic acid, electrolysis is carried out in the presence of a conducting salt where R 1 , R 2 , and R 3 are the same or different and are H or alkyl, at least one being alkyl, and R 4 is H or C 1 -C 6 alkyl. The aromatic compound may be a benzene derivative, a naphthalene, anthracene, phenanthrene, acenaphthene, acenaphthylene, tetracene, perylene or chrysene; the heterocyclic compound may be quinoline or benzofuran; substituent groups on the aromatics may be alkyl, aryl, alkoxy, aryloxy, halogen, acyloxy, acylamino, cyano, nitro, or sulphonate; examples are given. Alkanoic acids mentioned are formic, acetic, propionic, butyric, valeric, isovaleric, and caproic; said salt may be made by reacting a suitable amine with such acid and may be trimethylammonium formate, acetate or propionate; triethyl ammonium formate, acetate or propionate, tri-n-butylammonium acetate, dimethylammonium formate, acetate or propionate, or diethylammonium acetate. The anode may be graphite, PbO 2 , Pt or Au, and the cathode graphite, Fe, steel or Pb; the electrode spacing may be 0À25-2 mm. and the C.D. 0À1- 30 A/dm. 2 ; a charge of 0À4-1À5 F/mole causes monoacyloxylation, and >2F/mole a higher degree. The electrolyte may comprise 5-60 wt. per cent aromatic or heterocyclic compound, 5-70% alkanoic acid, 1-20% of the salt and 0-50% of an inert co-solvent; everything apart from the product may be removed afterwards by distillation.
