Title: The manufacture of di-potassium terephthalate
Inventor: GROOMBRIDGE WALTER HENRY
IPC: C07C51/41
Filed: 1954-09-22
Abstract: Di-potassium terephthalate is made by heating potassium benzoate at 300-500 DEG  C. in an autoclave charged initially under superatmospheric pressure with an inert gas free from carbon dioxide. The inert gas specified is nitrogen.  Instead of pure potassium benzoate, mixtures of potassium carbonate and benzoic acid, or mixtures of potassium and lithium benzoates or of potassium, sodium and lithium benzoates may be used.  Fusible salts may be present so that the mixture attains fluid form at the heating temperature. Other salts which are inert to potassium benzoate under the reaction conditions, diluents and metal turnings may also be present.  The potassium benzoate may be heated in thin layers or in a shaken or stirred autoclave.  After heating, the autoclave is cooled and the pressure released. Benzene may be condensed from the issuing gas. The solid product is ground and dissolved in water, the solution is filtered and terephthalic acid is obtained therefrom by acidification and purified by reprecipitation from alkali.  An example is given.
