Magnesium benzoate

In the Lummus process (Figure 10-15), the reaction occurs in the liquid phase at approximately 220-240°C over Mg " + Cu " benzoate. Magnesium benzoate is an initiator, with the Cu " reduced to Cu ". The copper (1) ions are reoxidized to copper (II) ions. [Pg.288]

The values of 8 the film thickness are found to vary with the nature of the reaction, but lie within the limits 0 02 to 0 065 mm. The film thickness is dependent on the speed of rotation n for the case of the solution of benzoic acid and of magnesium benzoate in water. [Pg.192]

Is this mechanism, the copper acts as a redox catalyst Various initiators are combined with it to catalyze the hydrolysis, including magnesium benzoate, or salts of different metals (Li, Na, K, Ba, Co, etc.. The main side reactions arc4he decarboxylation of benzoic acid to benzene, or its complete degradation, and the production of diphenyl ether and tars. These tars, produced essentially at the expense of phenol, mainly appear in the liquid phase. They slow down its rate of formation considerably, and make it necessary to extract the reaction medium as rapidly as possible ... [Pg.120]

The first step is a liquid phase air oxidation of toluene to benzoic acid. Air and toluene are fed continuously into the base of an autoclave containing benzoic acid and a cobalt acetate-manganese acetate catalyst at 110—150°C and about 3 atmospheres. About 50% of the toluene is converted per pass. The unreacted toluene is removed and recycled and the residual crude benzoic acid is purified by distillation or crystallization. In the second step benzoic acid, containing cupric benzoate as catalyst and magnesium benzoate as promoter, is heated to 230—240°C. Steam and air are passed into the melt. Phenol and benzoic acid are vaporized continuously and are separated by distillation. The overall yield of phenol is 70-75%. [Pg.278]
