| production method | prepared by catalytic hydrogenation of ethyl cinnamate. The hydrogenation reaction was carried out in an autoclave with chromium-copper-barium catalyst at a temperature of 200 ℃ and a hydrogen pressure of about 20MPa. After 5-9h of hydrogenation reaction, the catalyst was cooled and filtered, and the filtrate was extracted with ether. After the ether is recovered from the extract, it is distilled under reduced pressure, and the 110-112 ℃(1.06kPa) fraction is collected, which is the finished product, and the yield is about 85%. Another preparation method is the Grignard reaction of benzyl chloride and ethylene oxide to obtain 3-phenylpropanol chloromagnesium salt, and then hydrolyze with sulfuric acid to obtain 3-phenylpropanol. The yield of this method is about 65-70%. It is made by hydrogenation of cinnamyl alcohol or cinnamaldehyde. |
