| production method | cinnamon alcohol is stored in natural Suhe oil, Peruvian gum and cinnamon oil in the form of ester, and an appropriate amount of 10% caustic solution is added. It can be prepared by heating. There are many ways to synthesize cinnamyl alcohol. Cinnamyl cinnamate is saponified in alkaline medium to obtain cinnamyl alcohol with good quality; cinnamyl aldehyde is reduced by isopropenyl aluminum to obtain cinnamyl alcohol in a 73% yield; when cinnamyl aldehyde is reduced with benzyl alcohol aluminum When cinnamaldehyde, it will be steamed into benzaldehyde at the same time to obtain cinnamyl alcohol. The finished product is distilled under reduced pressure. The cinnamaldehyde is reduced by this method without touching the double bond of the side chain. cinnamaldehyde reduction method adds 0.01 parts of aluminum chips to 1 part of benzyl alcohol, heats to 60 ℃ to react and release hydrogen, and the temperature rises to 180 ℃ until hydrogen release is stopped. The benzyl alcohol aluminum solution is cooled and filtered and added to the mixture of benzyl alcohol and cinnamaldehyde (mass 1:1). Under the condition of 0.0027MPa heating to boiling, at 80 degrees C and reflux ratio of 3~4 steam out of the reaction of benzaldehyde, while adding benzyl alcohol. Until the theoretical amount of 95% benzaldehyde is steamed out, the feeding is stopped, and the remaining benzyl alcohol is steamed out, and then the crude cinnamon alcohol is steamed out. After vacuum distillation, the fraction at 117 ℃(7kPa) is collected, which is the product. Styrax saponification method Cinyl alcohol is naturally present in Peruvian balsam, benzoin and Styrax in the form of cinnamate. Styrax greens are heated and saponified in a 10% sodium hydroxide solution for 5h, and the hydrolysate cinnamyl alcohol is extracted with ether, and finally purified by vacuum distillation to obtain the finished product. The sulac fat containing cinnamate is saponified in the same amount of 10% caustic soda solution for 5 hours to obtain the hydrolysate cinnamol and cinnamic acid, then ether is used to produce cinnamol and purified by vacuum distillation. Soluble cinnamaldehyde in isopropanol, catalyzed by aluminum isopropoxide, fractionated at 70~80 ℃, reduced distillate is crude, then evaporated to isopropanol and reduced pressure distillation, purification, that is, pure product. |
