This invention relates to a process for the preparation of benzoic acid, and more particularly it relates to a process for the preparation of benzoic acid by the catalytic oxidation of toluene. It has long been known that small amounts of benzoic acid are obtained when toluene is oxidized......
Process for the preparation of benzoic acid derivatives A process for the preparation of a compound of the formula ##STR1## in which X.sup.1 and X.sup.2 each independently is chlorine or fluorine, andY is chlorine, bromine, fluorine or iodine, comprising subjecting a compound of the formu...
PURPOSE:To obtain high purity alkylsulfonylbenzoic acid, an intermediate of dyes, agricultural chemicals, photo graphic chemicals, etc., in high yield, by the oxidation of alkylsulfonylbenzaldehyde with a hypochlorite which is inexapnsive and easy to be handled. CONSTITUTION:Alkylsulfonylbenzoic acid...
At 350° benzyl benzoate undergoes a reaction of disproportionation. After two hours’ heating, the major products of change are benzoic an[1]hydride, toluene and benzaldehyde. Smaller amounts of benzoic acid were also indentified. Negative searches were made for stilbene, phenanthrene, benzene, ...
The catalysts of the invention exercise a high conversion of benzoic acid and a high selectivity to phenol, and phenol can be produced in a high yield, particularly in a high space time yield through the processes of the invention using the above catalysts. The above conversion, selectivity ...

CATALYSTS IN THE PREPARATION OF O-BENZOYLBENZOIC ACID AND ETHYLBENZENE... In the preparation of o-benzoylbenzoic acid from benzene and phthalic anhydride, ferric chloride is a much poorer catalyst than aluminum chloride, but an equimolecular mixture of ferric and aluminum chlorides, although less ac...
PURPOSE:To prepare the title resin giving a highly plastic laminated board resistant to the bulging and the lowering of electrical insulation, by the use of a modifying agent prepared by reacting oxybenzoic acid or its derivative with the terminal OH groups of a polyester of a dibasic acid and...
4-(1-METHYL-1H-PHENANTHRO[9,10-d]IMIDAZOLE-2-) BENZOIC ACID (MPIBA) AND ITS APPLICATION FOR DETERMINATION OF AMINES BY HIGH PERFORMANCE LIQUID CHROMATOGRAP... A simple, sensitive, and mild method for the determination of amines based on a condensation reaction with 1-ethyl-3-(3-dimethylam...
