Synthesis method of high-content dihydrojasmonic spice (by machine translation)

The synthetic method comprises the following steps: 2 - octanol serving as a solvent and di-tert-butyl peroxide as an initiator, and refluxing to separate t-butyl alcohol and water, vacuum distillation to obtain 2 - octyl 2 - (3H) furanone, and then dehydrating and dehydrating 5 - methyl -5 - hexyl -2 -2 -5 - (3H) furanone molecules under the action of a solid acid catalyst to recover the dihydrojasmonic spice product after the reflux reaction is carried out 5 . The synthesis method provided by the invention has the advantages of relatively simple steps, no acid waste water generation and high total yield, and moreover, the content of the product and the dihydrojasmonone synthesized through the synthetic method provided by the invention is higher than 98% and above.
