| titleOfInvention | A kind of preparation method of 3,5-dihydroxypentylbenzene |
| abstract | The present invention provides a method for preparing 3,5-dihydroxypentylbenzene. By using 3,5-dialkoxybenzoate compounds as raw materials, firstly react with valeronitrile to generate β-ketonitrile compounds, and then The cyano group is hydrolyzed to generate a carboxylic acid compound, and then through decarboxylation reaction to obtain 3,5-dialkoxy valerophenone, then through Huang Minglong reaction or catalytic hydrogenation, 3,5-dialkoxy valerophenone is converted into 3,5-dialkoxy valerophenone , 5-dialkoxypentylbenzene, and finally the alkoxy group is reduced to a phenolic hydroxyl group to obtain 3,5-dihydroxypentylbenzene. The preparation method of the invention solves the defects of high cost, complicated route, low yield, poor purity and the like of the traditional process. |
