Title: Low concentration trivalent chromium electroplating solution and process
IPC: C25D5/14
Filed: 1979-11-07
Abstract: A very low concentration (below 0.03 M) trivalent chromium plating bath in which the source of chromium is an equilibrated aqueous solution of a chromium (III) - thiocyanate complex gives a deposit of unexpectedly light color. Such a bath is employed to produce thin overcoatings of light colored chromium for decorative applications. The bath and process is also used to plate the initial layer of a thick (greater than 5 micron) deposit for engineering applications, the major part of which is plated from a higher chromium concentration bath. Such thick deposits from a higher concentration bath are more cohesive and smoother when plated over an initial layer from the low concentration bath.

Title: Process for preparing benzoic acid.
IPC: B01J31/00
Filed: 1980-08-28
Abstract: The invention relates to a process for preparing aromatic carboxylic acids by oxidation of an alkyl-aromatic hydrocarbon in the liquid phase in the absence of an aliphatic carboxylic acid, by means of a gas containing molecular oxygen and in the presence of a catalyst consisting of a cobalt compound that is soluble in the reaction mixture. The process according to the invention is characterized by the fact that in addition to the cobalt compound a catalyst is used that consists of a zirconium and/or hafnium compound soluble in the reaction mixture. The use of zirconium and/or hafnium as a catalyst in addition to cobalt enables a higher reaction rate to be reached at the same temperature, or the reaction to be carried out at a lower temperature with the same reaction rate, with a considerably better selectivity for the desired aromatic carboxylic acid being obtained at the same reaction rate than if only cobalt is used under otherwise identical conditions.
