Versuchsvorschrift

A mixture of 20 g. of N-(2-octyl)-p-phenylenediamine, 14 g. of 3-isopropoxypropionaldehyde and 0.3g. of 5% platinum sulfide on carbon catalyzt is shaken in a rocker bomb at 150°C under 600 psi hydrogen for 5 hours. After allowing the mixture to cool to room temperature, the contents of the bomb are dissolved in methanol and filtered through celite. The filtrate is evaporated in vacuo and the residue is taken up in ether and treated with an excess of dry hydrogen chloride gas. The resulant solid is collected by filtration and recrystallized from methanol-acetone to yield the product N-(3-isopropoxypropyl)-N'-(2-octyl)-p-phenylenediamine in dihydrochloride salt form (mp 200°-202°C).
