Patent GB-811952-A (GB)
Title: The preparation of cyclic dibasic acids
IPC: C07C51/02
Filed: 1957-01-16
Abstract: Cyclic dibasic acids are prepared by heating a salt of a cyclic carboxylic acid under known conditions on a fluidized bed consisting of a salt of the cyclic dibasic acid to be obtained. The term "cyclic dibasic acid" includes cyclic organic acids containing at least one carboxyl group and either a further carboxyl group or another salt forming acid group, e.g. a phenolic group.  The rearrangement may take place in the presence of carbon dioxide or a gas containing it and also a catalyst which may be an oxide or salt of zinc, cadmium or divalent iron. Organic salts of these metals, e.g. a salt of the acid to be prepared, are particularly suitable.  The starting materials may be the potassium or thallium salts or a mixture with a sodium salt of benzoic, phthalic, isophthalic, hemimellitic, trimellitic, pyromellitic, mellitic, mellophonic, prehnitic or trimesic acids. Hydroxy monocarboxylic acids may be prepared by this method and naphthalic, 2-hydroxy-naphthalene-1-carboxylic, salicylic, diphenic and pyridine carboxylic acids may also be used as starting material. The salts may be prepared in situ by heating the acid or anhydride with the metal hydroxide or carbonate.  The fluidized bed consists of particles, preferably of between 0.5 and 3 mm. grain size, of a salt of the acid to be produced and it is kept in a fluidized state by blowing hot carbon dioxide or carbon dioxide/nitrogen into it through nozzles or through a grid. These hot gases maintain the high temperature for the reaction which may be in the range 250-450 DEG C., preferably 400-440 DEG  C. The reactants containing the catalyst are fed in continuously to the reaction vessel and the products removed through a screw conveyer.  The acid may be recovered from its salt by treatment with a solution of the starting acid which is itself converted to salt and hence may be used as a reactant in a later process.  In examples (i) dipotassium phthalate containing cadmium oxide catalyst is heated on a fluidized bed of dipotassium terephthalate at 410 DEG  C.  The terephthalic acid is recovered by treating the salt with phthalic acid at 130 DEG  C.; (ii) a mixture of sodium and potassium benzoate containing cadmium benzoate is heated on a dipotassium terephthalate bed at 430 DEG  C.  The acid is recovered from its salt by treatment with benzoic acid.
