Benzoic acid reacts with phosphorus pentaoxide in the presence of heat to give ________

Benzoic acid reacts with phosphorus pentaoxide in the presence of heat to give ________ Correct Answer C6H5COOCOC6H5

Benzoic acid on heating with a strong dehydrating agent like P2O5 forms its corresponding anhydride, i.e., benzoic anhydride, which consists of two C6H5C=O groups bridged by a (-O-) group.

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
