The styrolene compounds are, as a group, remarkable in that they often possess floral odours. Thus, the a/ta-substitution products of styrolene C, jH5. CH: CH2, such as bromstyrolene C6H5. CH: CHBr, have usually a distinct hyacinthlike odour. Styrolene alcohol C6H6. CH(OH)CH2OH is identical with phenyl-glycol, the basis of the above-mentioned French patent; whilst secondary styrolyl acetate C6H5. CH(0. CO. CH3)CH3 has itself a marked odour of jasmin. This body can be prepared by the action of bromine on boiling ethyl-benzene. The resulting bromide is heated with silver acetate and glacial acetic acid, yielding styrolyl acetate. Artificial oil of jasmin compounded on the lines of the above-mentioned facts is now a regular article of commerce.
