| titleOfInvention | Preparation method for nitro aromatic alcohol |
| abstract | The invention discloses a preparation method for nitro aromatic alcohol. The method comprises the steps of: a. mixing R1CHO, R2CH2NO2, a catalyst and a polar organic solvent evenly, carrying out stirring reaction for 6h-48h at 0DEG C-40DEG C to obtain a reaction product; b. removing the solvent from the reaction product of step a, and performing silica gel column chromatography to obtain an oil product, i.e. nitro aromatic alcohol. The catalyst adopted by the invention is significantly different the catalysts for preparation of nitro aromatic alcohol by the prior art, and has the advantages of simple structure, convenience and easy availability, low price, and high product yield, etc. Particularly, when triethylene diamine is adopted as the catalyst, the yield of nitro aromatic alcohol can reach over 95%. The method has the advantages of simple operation, low cost and the like, and has good industrial application prospects. |
