Abstract: A process for the preparation of a mixture of carbon tetrachloride and phosgene in the absence of a catalyst from A. OXYGEN-CONTAINING CARBON-HYDROGEN COMPOUNDS OR B. OXYGEN-CONTAINING CARBON-HYDROGEN COMPOUNDS, CARBON MONOXIDE, CARBON DIOXIDE, OR WATER, IN ADMIXTURE WITH AROMATIC, CHLORINATED AROMATIC, CHLORINATED ALIPHATIC, OR CHLORINATED CYCLO-ALIPHATIC HYDROCARBONS, WITH CHLORINE AT AN ELEVATED TEMPERATURE AND PRESSURE.

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 DEG to 400 DEG C. and in the second stage of from 400 DEG to 800 DEG 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: Cyclohexane-1,3-diones of the formula having up to 24 carbon atoms are prepared in admixture with 6-alkyl-3,4-dihydro-2-pyranones of the formula having up to 24 carbon atoms, in which formulae the radicals R and R' may be identical or different and represent each a hydrogen atom, an alkyl, a cycloalkyl or an aryl group each having up to 12 carbon atoms and the two radicals R' together optionally represent a -(CH2)3-group, by passing 4-oxocarboxylic acids of the formula having up to 24 carbon atoms and in which R and R' have the above meaning at a temperature of from 250 DEG to 500 DEG C in the gaseous phase over a dehydration catalyst and the pyranones are converted into cyclohexane-1,3-diones by passing them in the gaseous phase over a dehydration catalyst at a temperature of from 250 DEG to 500 DEG C.
