| titleOfInvention | Method for preparing alpha-o-nitrobenzene ethanol by oxidizing o-nitroethylbenzene without catalyst oxygen |
| abstract | A method for preparing alpha-o-nitroacetophenol by oxidizing o-nitroethylbenzene without catalyst oxygen relates to a preparation method of alpha-o-nitroacetophenol. Under the condition of not adding any catalyst, taking o-nitroethylbenzene as a raw material, taking oxygen as an oxidant, taking sodium hydroxide as alkali, reacting in an alcohol solvent at the reaction temperature of 25-65 ℃, and separating and purifying to obtain the alpha-o-nitroanisole. The method does not need a catalyst; the raw materials are low in price; ethanol can be used as a solvent, and the solvent is almost nontoxic, cheap and easy to recycle; the reaction temperature is moderate, and the production control is easy; the conversion rate of raw materials is high; the target product has high selectivity and yield up to 88 percent, and has wide application prospect. |
