Article abstract of DOI:10.1039/f19837901987

The rate constants, k, for the decomposition of ammonium trichloroacetate in acetonitrile were determined at 298 K where B is an N-base.The first-order decarboxylation of trichloroacetic acid in the presence of N-bases is strongly deopendent upon proton transfer in complexes.Discussion of the rate constants, k, obtained shows 3 types of complexes in the proton-transfer mechanism, i.e. a symmetrically positioned proton, and without proton transfer for 2 cases: .The sigmoidal curve of rate constants, -log k, plotted against (pKa)AN describes the location of the proton in the hydrogen bridge.The behaviour of (CCl3COOHR)(1-) complexes has many similarities to the molecular complexes, CCl3COOHB, discussed above.Implications of these results for carboxylate additives in overbased lubricating oils are discussed.
