| titleOfInvention | A kind of synthetic method of cis (trans)-8-dodecenol acetate |
| abstract | The invention discloses a method for synthesizing cis (trans)-8-dodecenol acetate, comprising the steps of: placing 1,8-octanediol in an aqueous acetic acid solution at room temperature, using sulfuric acid as a catalyst, Constant stirring to make it react; the reaction system is continuously extracted with petroleum ether in a centrifugal extractor, and after the petroleum ether is recovered by distillation, 8-acetoxy-1-octanol is obtained; 8-acetoxy-1-octanol is obtained Add water, ethyl acetate, sodium bromide and sodium acetate trihydrate, add tetramethylpiperidine oxide after stirring, add sodium hypochlorite dropwise, stir while adding dropwise, the reaction generates 8-acetoxy-1-octane Aldehyde; add butyl triphenylphosphine bromide to tetrahydrofuran, add organic base dropwise while stirring, make it react, continue to dropwise add 8-acetoxy-1-octanal, make it carry out wittig reaction, generate cis (Trans)-8-Dodecenol acetate. The method has the advantages of short period, few steps, high yield, simple post-processing and the like, and is suitable for large-scale industrial production. |
