1. Preparation of Fragrance And Spices cas 122-97-4: Ethyl cinnamate catalytic hydrogenation in the system. The hydrogenation reaction was carried out in an autoclave using a chromium-copper-barium catalyst at a temperature of 200 ° C and a hydrogen pressure of about 20 MPa. After hydrogenation reaction for 5-9 h, the catalyst was filtered off and the filtrate was extracted with ether. The extract was recovered by distillation under reduced pressure, and the fraction was 110-112 ° C (1.06 kPa), and the yield was about 85%. Another Fragrance And Spices cas 122-97-4 method is the preparation of benzyl chloride and ethylene oxide through Grignard reaction 3-phenylpropanol chloride magnesium salt, and then sulfuric acid hydrolysis to 3-phenyl propanol. The yield of this method is about 65-70%.
2. Method of Fragrance And Spices cas 122-97-4: Ethyl cinnamate was added to the autoclave
(2) 57 g (0.32 mol), 5 g chromium-copper-barium catalyst, sealed reactor. The air was replaced with nitrogen and the nitrogen was replaced with hydrogen. Through the hydrogen to the pressure of 20MPa, until the hydrogen is no longer absorbed, about 5 ~ 9h. After completion of the reaction, the remaining pressure was separated, the reaction kettle was opened, the liquid was removed, the catalyst was filtered off, and the ether was washed. The ether was distilled off and fractionated under reduced pressure to collect 110 to 112 ° C / 1.06 kPa fraction to give 3-phenyl-1-benzyl alcohol
Use of Fragrance And Spices cas 122-97-4
