Production Method (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%。
(2) The hydrogenation of peruvin or cinnamaldehyde.
