Questions And Answer

• Chemical properties

  Colorless viscous liquid with a sweet scent of flowers and sweetmeat and the flavor of fresh fruit after dilution. Its boiling point is at 236 °C, flash point at 109 °C. Soluble in ethanol, propylene glycol and most of the non-volatile oil, insoluble in glycerol and mineral oil, slightly soluble in water (1: 300).
  Natural 3-Phenyl-1-propanol can be found in strawberries, Styrax cream, benzoin cream, tea, Peru Balsam, Cassia leaf oil, cinnamon oil and so on.;

• Uses

• 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.;
