Chemistry & Uses
Uses in perfumery :
Benzyl Alcohol is used in majority as a solvent for some ingredients, even if it is rarely the case. It can also be used is some white flowers accords, to bring volatility.
Year of discovery :
Data not available.
Natural availability :
Benzyl Alcohol is found in low quantity in many natural ingredients. It is found for example in Clove Leaf EO, Damask Rose Absolute and Narcissus Absolute.
Isomerism :
Benzyl Alcohol is an isomer of para-Cresol. These two molecules, although close structurally speaking, do not have the same smell at all, much more animalic on para-Cresol part.
Synthesis precursor :
Benzyl Alcohol can be used to synthesize Benzaldehyde, by adding nitric acid to oxydize it. This oxydation can also be carried out with copper-magnesium oxide pumice. Numerous esterifications can be carried out using Benzyl Alcohol, to obtain compounds as Benzyl acetate, Benzyl Salicylate... Eventually, heating this molecule with strong acids or bases may form Dibenzyl Oxide.
Synthesis route :
Two synthetic routes can be used to obtain Benzyl Alcohol. The first one is a hydrolysis of benzyl chloride, by heating this molecule with alkaline and earthy-alkaline hydroxydes and carbonates. Up to 10% Dibenzyl Ether is also resulting from this reaction. A second route is an oxydation of toluene into benzyl hydroperoxyde. Subsequent hydrolysis synthesizes Benzyl Alcohol and Benzaldehyde. A purification can then isolate Benzyl Alcohol.
Stability :
Aromatic compounds are chromophorous. This means that they may colour through time or in an alkaline medium.
Other comments :
In perfumery, using a benzylic molecule brings a fruity white flower note as jasmine. A long homologous molecule of Benzyl Alcohol is Phenyl Ethyl Alcohol, bringing a rosy note. By lengthening even more the chain, a dihydrocinnamic body brings more heavy floral balsamic note.
Benzyl Alcohol is part of the 26 allergens used in perfumery.
