Title: Improvements in or relating to the preparation of benzoic acid from cumene
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: C07C51/265
Filed: 1956-09-25
Abstract: Benzoic acid is made by oxidising cumene by means of oxygen or an oxygen-containing gas in the presence of an oxidation catalyst, the reaction being carried out in a liquid medium, which is stable under the oxidation conditions used, and n the conjoint presence of a metal ion and a bromide ion.  The liquid medium may be a carboxylic acid such as benzoic acid, acetic acid or propionic acid.  The catalyst may be a metallic oxide or salt, e.g. manganese acetate or cobalt acetate.  The salt may comprise both the catalytic metal ion and the bromide ion, e.g. manganese bromide, or cobalt bromide.  When benzoic acid is used as the liquid medium, the process may be integrated with that for the production of terephthalic acid.  Benzene is propylated to cumene, which is converted into benzoic acid by the process of the invention.  The benzoic acid is then converted into terephthalic acid, via the potassium salt; the byproduct of this step being benzene which is recycled to the propylation step.  In an example, oxygen is led, at the rate of 5 litres per hour, for 10 hours into a mixture of cumene (1 part), benzoic acid (5 parts), manganese bromide (0,005 parts) and cobalt bromide (0,005 parts) maintained under reflux.  The yield of benzoic acid is 90%. Specification 833,438 is referred to.

Divided out of 457,881, [Group II]. [Class 78 (i)] In an apparatus for sorting tennis balls and other spherical objects according to size as described in Specifications 457,881 and 457,920, [Group II], the balls are conveyed from a hopper 2 to the sorting device 1 by an inclined shoot 3, provided with a movable base 31 which is given a jerky reciprocating movement to dislodge any balls which tend to stop in the shoot. The movement of the base is obtained from the motor shaft 16 through an eccentric 35, yielding connection 70, and crank-shaft 36. The latter is connected by a cable 37 to the movable base 31 through a pin-and-slot connection 40, the base moving against the action of a spring 38.

Abstract: 1:1 - Bis - (chloro - phenyl or-tolyl) -2:2:2 - trichloroethanols are prepared by forming an aqueous mixture of a 1:1-bis-(chloro-phenyl or -tolyl)-1:2:2:2-tetrachloroethane, sulphuric acid and a hydrocarbon (including substituted hydrocarbon) sulphonic acid, the weight ratio of sulphonic acid to sulphuric acid being from about 99,5:0,5 to about 47:53 and the weight ratio of both these acids together to the tetrachloroethane compound being 0,05:1 to 2:1, heating the mixture and maintaining the temperature thereof between about 125 and 165 DEG C., while maintaining sufficient water in the reaction mixture for the hydrolysis of the 1-chloro substituent. Advantageously, the weight ratio of sulphonic to sulphuric acid is from 99,3:0,7 to 85:15 and during the course of the reaction there is desirably present in the reaction mixture, on a weight basis, 35 to 85 parts of sulphonic acid, 0,5 to 39 parts of sulphuric acid and 14,5 to 30 parts of water per 100 part of these three components combined, and most preferably 70 to 85 parts of sulphonic acid, 0,5 to 15 parts of sulphuric acid and 14,5 to 29,5 parts of water.  The preferred ratio of the combined acids to the chloro compound is from 0,1:1 to 1:1 and most preferably 0,2:1 to 0,5:1 and the preferred reaction temperature is 135 to 150 DEG C.  The reaction is advantageously carried out under reflux conditions, water being added during the reaction to maintain the desired temperature of reflux until the theoretical amount of hydrogen chloride has been evolved.  The product may be isolated from the cooled reaction mixture by extraction with a water-immiscible solvent such as naphtha, toluene, xylene or a chlorinated hydrocarbon.  The sulphonic acid used is preferably an alkyl or aryl sulphonic acid, desirably containing at most 12 carbon atoms, such as toluene-, naphthalene-, chlorobenzene- or ethylsulphonic acid, although other similar sulphonic acids, including disulphonic acids and commercial mixtures of sulphonic acids are also referred to. Examples are given, the products obtained including impure oils containing predominantly 1:1-bis-(p-chlorophenyl)-2:2:2-tri chloroethanol and some 1-(p-chlorophenyl)-1-(o-chlorophenyl)-2:2:2-trichloroethanol and these compounds as pure crystals obtained by crystallization techniques.  1:1-Bis - (chlorophenyl) - 1:2:2:2:2-tetrachloroethanes are prepared from 1:1-bis-(chlorophenyl) -2:2:2-trichloroethanes, eitherby direct chlorination or by dehydrochlorination to give the corresponding bis-(chlorophenyl)-dichloroethylenes which are then chlorinated.
