(1) the catalytic hydrogenation of ethyl cinnamate.
The hydrogenation reaction is conducted in autoclave with chromium-copper-barium catalyst at 200℃ and 20MPa for 5-9h. The filtrate obtained after cooling and filtration is extracted by diethyl ether. After the recycling of diethyl ether, reduced pressure distillation of the extracting solution is conducted to collect the fraction of 110-112℃（1.06kPa）, which is the finished product. The yield is about 85%.
Grignard reaction of benzyl chloride and oxirane, followed by the hydrolysis with sulfuric acid to obtain 3-Phenyl-1-propanol. The yield is about 65-70%。

Chemical Properties
CLEAR COLOURLESS LIQUID
Chemical Properties
3-Phenyl-1-propanol occurs both in free and esterified forms in resins and balsams (e.g., benzoe resin and Peru balsam). It has been identified in fruits and cinnamon.
Hydrocinnamic alcohol is a slightly viscous, colorless liquid with a floralbalsamic odor, slightly reminiscent of hyacinths. Esterification with aliphatic carboxylic acids is important because it leads to additional fragrance and flavor materials.
Hydrocinnamic alcohol is prepared by hydrogenation of cinnamaldehyde. A mixture of hydrocinnamic alcohol and the isomeric 2-phenylpropanol can be obtained from styrene by a modified oxo synthesis. The two isomers can be separated by distillation.
Hydrocinnamic alcohol is used in blossom compositions for balsamic and oriental notes.
