Chemistry & Uses
Year of discovery :
Data not available.
Natural availability :
Phenyl Propyl Alcohol extraction is possible from Siam Benzoin Resinoid (and other origins), Peru Balsam Resinoid or Ceylon Cinnamon EO (and other origins).
Isomerism :
Phenyl Propyl Alcohol positional isomer, 2-Phenylpropanol, has a more green and spicy smell. The other isomer, 1-Phenylpropanol is less cinnamic and more floral.
Synthesis precursor :
Phenyl Propyl Alcohol is a precursor to the synthesis of Phenyl Propyl Aldehyde by reduction and Phenyl Propyl Acid by oxidation. Its esters also have an olfactory importance.
Synthesis route :
Its synthesis can be done in two ways. The first is a catalytic hydrogenation of Cinnamaldehyde, obtained by synthesis or from Cassia EO. An oxo synthesis modified from styrene causes the formation of the Phenylpropyl Alcohol, but also of its positional isomer, 2-Phenylpropanol. The two isomers can be separated by a fractional distillation.
Stability :
Most of the time, the occurrence of a benzenic cycle in a molecule causes a coloration of this molecule through time
Other comments :
Phenyl Propyl Alcohol is more honeyed, warm and cinnamic than Phenyl Ethyl Alcohol.
