Answer:
Preparation of benzoic acid
Preparation of benzoic acid by hydrolyzing benzonitrile
Explanation:
A mixture of 5 ml (or 5.1 g) of benzonitrile and 75 ml of 10% aqueous sodium hydroxide is boiled under a reflux condenser until oily drops of benzonitrile disappears. The condenser is then detached and boiled in the open flask for a few minutes in order to remove free ammonia. Then the solution is cooled and neutralized by adding concentrated hydrochloric until precipitation of benzoic acid is complete. The crystals of benzoic acid are collected by filtration, washed well with cold water and dried. Yield is about 5.8 g. Benzoic acid is purified by crystallization from hot water yielding product, which melts at 121° C.
