Chinese name: 3 - phenyl propyl alcohol English name: 3 - phenylpropanol Alias: gamma - Phenyl propyl alcohol, hydrogenated cinnamic alcohol, gamma hydroxy propyl benzene, 3 - Phenyl propyl alcohol, eczema, alcohol, 3 - Phenyl - 1 - propanol, 3 - Phenylpropyl alcohol, Hydrocinnamyl alcohol, 3 - Phenyl - 1 - propanol. CAS no. : 122-97-4 Molecular formula: C9H12O Molecular weight: 136.19 EINECS no. : 204-587-6 Physical and chemical properties: Density: 1.001 g/mL at 20 ° C Melting point: 18 ° c. Boiling point: 119-121 ° C / 12 mmHg Refractive index nD20:1.5365 Flash: 120 ° C. Colorless or light yellow oily liquid. There are fruit. Solubility: slightly soluble in water, 10.3 g/l (20 ° C), water soluble in methanol, benzene, cyclohexane and ethyl acetate. Natural products found in strawberries, styrax paste, benzoin extract, tea, Peru ointment, cassia leaf oil, cinnamon oil, etc. Purpose: GB 2760-1996 rules for temporary permits the use of edible spices. Is used to make peach, apricot, plum, watermelon, plum, strawberry, and walnut, hazel nuts type essence. Usage: used for spices, drug synthesis. Pharmaceutical industry is the strong central skeletal muscle relaxant dish of pine intermediates. The goods have sweet floral aroma and sweet candied fruit aroma, freshness after dilution happy melon and fruit fragrance. Natural products found in strawberries, fungus ointment, benzoin extract, tea, cassia leaf oil, such as our country GB2760-86 rules for temporary permits the use of flavouring agent. Application: suitable for cholecystitis, cholangitis, cholelith disease, biliary postoperative syndrome, and hypercholesterolemia Usage: used for synthetic spices, and pharmaceuticals. The pharmaceutical industry is the central of skeletal muscle relaxant strong pine intermediates. As preservatives in cosmetics, 3 - phenyl propyl alcohol with natural fragrance of bacteria and mildew antibacterial properties. So in combination with piperonal or pepper as the cosmetics preservatives. 3 - phenyl propyl alcohol or its ester derivatives are used as the fragrance of flowers, such as lilac, hyacinth, and since it has characteristics of balsamic vinegar smell also as part of the lilies of the valley. Production methods By cinnamic acid ethyl ester hydrogenation. Hydrogenation reaction in the autoclave, the use of chromium - copper - barium catalyst, the temperature is 200 ℃, about 20 mpa hydrogen pressure. After hydrogenation reaction of 5-9 h, cooling filter to catalyst, the filtrate extracted with ether. After recycling ethyl ether extract reduced pressure distillation, collected 110-112 ℃ (1.06 kPa) fraction, is the finished product, yield of about 85%. Another method is to benzyl chloride with ethylene oxide by grignard reaction get a 3 - phenyl propyl chloride magnesium salt, then use sulfuric acid hydrolysis get a 3 - phenyl propyl alcohol. This method about 65-70% yield. Production methods Composed of cinnamyl alcohol or cinnamic aldehyde hydrogenation.
