Abstract: ALKALI METAL SALTS OF TEREPHTHALIC ACID ARE FORMED FROM SALTS OF AROMATIC CARBOXYLIC ACIDS BY HEATING THE RAW MATERIALS IN A REACTOR UNDER CONTROLLED CONDITIONS OF STIRRING AND HEAT TRANSFER SO THAT THE TEMPERATURE DISTRIBUTION GRADIENT FROM THE HEAT TRANSFER SURFACE TO THE INNER PART OF THE REACTOR IS INTIALLY HIGH AND IS GRADUALLY LOWERED, WHEREBY POWDERED OR GRANULAR REACTION PRODUCTS ARE RECOVERED.

Abstract: Both cyclohexanone and alkyl-substituted or unsubstituted phenol are simultaneously produced, in a one step reaction, by oxidizing, in the liquid phase, an alkyl-substituted or unsubstituted phenylcyclohexane of the formula (I): (I) wherein R represents either a hydrogen atom or a methyl radical with an oxidizing gas containing molecular oxygen therein in the presence of hydrogen bromide.

Abstract: Alkali metal aromatic dicarboxylic acid salts are prepared by reacting together under pressure an alkali metal aromatic monocarboxylic acid salt with an alkali metal carbonate and carbon monoxide in presence of a carboxylation catalyst and carbon dioxide at 250 DEG to 500 DEG C. Preferably the reaction takes place at 100 to 400 atmospheres pressure and the molar ratio of carbon monoxide to carbon dioxide in the reaction medium is 90:10 to 10:90. Inert gases, e.g. methane, hydrogen or nitrogen may be present. Specified starting materials are the potassium, lithium, sodium or caesium benzoates, methyl benzoates and naphthoates. Carbonates used are carbonates of potassium, lithium sodium or caesium. Catalysts used preferably in amounts of 0.05 to 25% by weight based on the starting material are carbon, metallic cadmium, zinc, iron, titanium, lead, copper, aluminium and silicon alone or in ad-mixture with oxides, halides, carbonates of the above metals, organic acid and complex salts. The product may be dissolved in water and the free dicarboxylic acids may be precipitated by addition of mineral acid or extraction with ether or acetone.
