Ethyl ketone → N-(1-ethylpropyl)-3,4-dimethylaniline

참여 물질

반응 단계

A mixture of 151 grams (1.0 mole) 4-nitro-o-xylene, 138 grams (1.6 moles) diethyl ketone, 5.8 grams of 5% platinum on carbon and 3.7 grams of 2-naphthalenesulfonic acid monohydrate were added to a pressure vessel. Hydrogen was fed into the reactor at a pressure of 30-40 psi and a temperature of 80°-100° C. When hydrogen uptake ceased, the vessel was cooled and vented. After filtering the catalyst, the aqueous phase was separated and the upper layer concentrated in vacuo to give 191 grams of 96% pure N-(1-ethylpropyl)-3,4-xylidine (96% yield).
