As early as 1967, IFF chemists (11), in an in-depth study of jasmin absolute, identified an ultratrace amount of one of the key compounds in the entire fragrance repoitoire, hydroxycitroneUal [107-75-7] (21). This chemical has been used for many years in almost every "white flower" fragrance to give a very diffusive and lasting lily-of-the-valley and jasmin note, but this represents the only known identification of the compound in nature. This illustrates that the human nose can often predict the presence of a molecule well before the instmmentation becomes sufficiently sensitive to detect it. 

The sulfur dioxide can be recovered and recycled. The myrcenol, after purification by distillation, can condense with acrolein to produce Lyral [31906-04-4], an important aldehyde with a strong-lasting odor similar to Lily-of-the-valley (92). 

Epoxidation of diliydromyrcenol gives an iatemiediate epoxide that can be hydrogenated to hydroxycitronellol. Treatment of the diol with acid can also give the a-,P-citroneUol and the a-citroneUol can be isomerized to the P-citroneUol (27) (110). The diol, hydroxycitronellol, is also useful for produciag hydroxycitroneUal, a lily-of-the-valley fragrance material. 

Twenty-four years before its detection in nature PEA was first synthesized in 1876 (56) by reducing phenylacetaldehyde [122-78-1] with sodium amalgam. Then, in 1900, it was independently identified in otto of rose (57) and rose water (58). Subsequently, PEA has been identified in numerous flower oils such as ylang-ylang, narcissus, hyacinth, lily, neroH, and geranium as well as various other natural products like tea, tobacco, orange juice, beer, cigarette smoke, etc. 

Uses. Cinnamyl alcohol and its esters, especially cinnamyl acetate, are widely employed in perfumery because of their excellent sensory and fixative properties. They are frequently used in blossom compositions such as lilac, jasmine, lily of the valley, hyacinth, and gardenia to impart balsamic and oriental notes to the fragrance. In addition, they ate utilized as modifiers in berry, nut, and spice flavor systems. The value of cinnamyl alcohol has also been mentioned in a variety of appHcations which include the production of photosensitive polymers (49), the creation of inks for multicolor printing (50), the formulation of animal repellent compositions (51), and the development of effective insect attractants (52).

Erfume base to the extent of from 1 to 2 per cent. The alcohols may used in quantities up to 5 per cent. Laurinic alcohol is very suitable as a basis for perfumes of the lily type, owing to its delicate odour it has, moreover, very powerful fixative properties. 

This alcohol appears to be almost odourless, but when a dilute solution in alcohol is allowed to evaporate slowly, a very fine lily-of-the-valley odour is developed, together with the suggestion of cedar-wood oil. 

Linalyl Propionate.—This ester is also produced by condensing the free alcohol and the free acid by means of sulphuric acid. It has a somewhat fruity odour recalling that of bergamot, and is especially suitable for perfumes of the lily of the valley type. It is a colourless oil, boiling at 115° at 10 mm. pressure. 

It is prepared synthetically and has an intensely powerful odour of the lily or lilac type.
