Abstract: In the process for the manufacture of carbon tetrachloride from benzene, mixtures of benzene and chlorinated aliphatic or aromatic compounds, or chlorinated aromatic compounds, with chlorine in an excess amount of up to 300 percent, in the absence of catalysts in the gaseous phase in two reaction stages at a temperature in the first stage of from 6* to 400* C. and in the second stage of from 400* to 800* C. the space-time-yield is considerably increased by operating in both reaction stages under a pressure in the range of from 200 to 700 atmospheres. The reaction is carried out in a corrosion resistant reactor in continuous manner using 0.2 to 4 moles of organic compound or compounds per liter of reaction space per second.

Abstract: Solid gold hydroxydiacetate of the formula Au(OH)(O2CCH3)2 which is well suitable as catalyst or catalyst component for oxidation reactions. The novel compound can be obtained by preparing an aqueous solution containing gold ions and acetate ions, removing the solvent, dissolving the residue obtained in a polar solvent precipitating the gold hydroxydiacetate by adding a non polar solvent and isolating it.
