Halogenated aromatic carboxylic acids are prepared in high yield by the liquid phase oxidation of halogenated alkylbenzenes in the presence of a heavy metal oxidation catalyst and a vicinal epoxide having from 2 to 8 carbon atoms.

Process for the production of halogenated aromatic carboxylic acids

Loss-of-dry inhibitors for surface-coating compositions containing oxidizable organic vehicles comprise metal salt solutions that contain 0.05 to 1.5% by weight of cobalt, 0.5 to 3.5% by weight of calcium, and 0.5 to 5.0% by weight of zinc or zirconium. The metals are present in the loss-of-dry inhibitor as salts of branched-chain aliphatic monocarboxylic acids having 6 to 14 carbon atoms, cycloaliphatic monocarboxylic acids having 6 to 10 carbon atoms, or mixtures of these acids.

Loss-of-dry inhibitors for surface-coating compositions

Stable solutions that contain at least 7.5% by weight of dissolved chromium comprise an organic solvent and a mixture of chromium salts that contains at least one chromium salt of a straight-chain aliphatic monocarboxylic acid having 5 to 10 carbon atoms and at least one chromium salt of a branched-chain aliphatic monocarboxylic acid having 5 to 10 carbon atoms.
