It is excreted when many aromatic compounds, such as benzoic acid and toluene, are taken internally.
OH, in which we will assume the hydroxyl group to occupy position I, is converted into brombenzene, which is then converted into benzoic acid, C 6 1-1 5 -COOH.
Resins when soft are known as oleo-resins, and when containing benzoic or cinnamic acid they are called balsams. Other resinous products are in their natural condition mixed with gum or mucilaginous substances and known as gum-resins.
Styrolene is oxidized by nitric or chromic acids to benzoic acid; reduction gives ethylbenzene; hydrochloric and hydrobromic acids yield a-haloid ethylbenzenes, e.g.
On the other hand, it differs from the aliphatic aldehydes in many respects; it does not form an addition product with ammonia but condenses to hydrobenzamide (C 6 H 5 CH) 3 N 2; on shaking with alcoholic potash it undergoes simultaneous oxidation and reduction, giving benzoic acid and benzyl alcohol (S.
Hexahydrobenzoic acid, C 6 H 11 CO 2 I-I, is obtained by the reduction of benzoic acid, or by the condensation of 1.5 dibrompentane with disodio-malonic ester.
Nitric acid oxidizes it to benzoic acid and acetic acid.
Ethyl benzoate, C 6 H S 000C 2 H 5, is best prepared by boiling benzoic acid and alcohol with a small quantity of sulphuric acid for some hours (E.
An, matter), formed the basis of benzaldehyde, benzoic acid, benzoyl chloride, benzoyl bromide and benzoyl sulphide, benzamide and benzoic ether.
Nitration of benzoic acid gives chiefly meta-nitro-benzoic acid.
