| titleOfInvention | Method for preparing m-beta-ethoxyl sulphone aniline |
| abstract | The invention provides a method for preparing m-beta-ethoxyl sulphone aniline. The method comprises the following steps of: 1) mixing m-beta-ethoxyl sulphone nitrobenzene and methanol aqueous solution with the volume percentage of 90%-99%, and adding the mixture into a reaction kettle; 2) adding a nano-nickel catalyst into the reaction kettle in the step 1); 3) rising the temperature of the reaction kettle to 70-90 DEG C, increasing the pressure of the reaction kettle to 1-2.5Mpa, wherein the reaction time is 85-170min, the ratio between the m-beta-ethoxyl sulphone nitrobenzene and the methanol aqueous solution is 1g:2ml, the added amount of the nano-nickel catalyst accounts for 7.5% of the mass of the m-beta-ethoxyl sulphone nitrobenzene. The method provided by the invention has the beneficial effects that the problem of serious environmental pollution due to use of iron powder or skeletal nickel as a catalyst in the traditional preparation method is solved, simultaneously the reaction condition is mild, not only is the pollution less and is the cost low, but also the reaction time is short and the conversion ratio is high. |
