Versuchsvorschrift

182 parts of N-ethylaniline, 150 parts of n-butanol and 10 parts of triphenyl phosphite are heated for 20 hours at 230° C in a stirred autoclave. The autoclave is then let down and the water of reaction formed, unconverted ethylaniline and excess alcohol are distilled off. 183 parts of N-ethyl-N-butyl-aniline, corresponding to a yield of 69% of theory, distil at a boiling point of 88° - 91° C/5 mm Hg.
