Methyl Ethyl Ketone → N-(1-methylpropyl)-3,4-dimethyl-aniline

참여 물질

반응 단계

A mixture of 151.2 grams (1.0 mole) 4-nitro-o-xylene, 161 grams (2.2 moles) methyl ethyl ketone, 6 grams of 5% platinum on carbon and 4.5 g of 2-nahthalenesulfonic acid monohydrate were added to a pressure vessel. Hydrogen was fed into the pressure vessel at a pressure of 20 psig. When hydrogen uptake ceased (in about 2 hours), the vessel was vented and the reaction mixture filtered. The phases were separated and the organic phase was concentrated in vacuo (at 20 mm and 70° C.) to give 178.8 g of 96.4% pure N-(sec-butyl)-3,4-xylidine in a yield of 97.2%.
