Title: Synthetic lilac perfume
Date(s): 1937-09
Contributor(s): E.I. du Pont de Nemours & Company (originator), Duryea, Drix (photographer)
Description: Large bottles of terpineol, the chief constituent of synthetic lilac perfume. Reflected in the vessels of crystal clear oil are the large drums of the raw materials for perfume manufacture. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery- there was no lilac perfume, for no satisfactory mean has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor...

Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery- there was no lilac perfume, for no satisfactory mean has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor as synthetic lilac. Chemistry converts volatile turpentine into fragrant lilac rivaling natural's illusive floral fragrances.
