Alkyl- or cycloalkenoaniline by vapor-phase amination of alkyl- or cycloalkenophenol with excess ammonia in the presence of an acid catalyst

Alkyl- or cycloalkenoaniline by vapor-phase amination of alkyl- or cycloalkenophenol with excess ammonia in the presence of an acid catalyst. Loehnert, Gernot; Hausigk, Hanf D. (Ruetgerswerke A.-G., Ger.). Ger. Offen. DE 2516316 21 Oct 1976, 8 pp. (German). (Germany).Some commonly used reagents like 578-54-1 and 1470-94-6 are used in this experiment. CODEN: GWXXBX. CLASS: IC: C07C087-50. APPLICATION: DE 75-2516316 15 Apr 1975. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) A 1:0.1-3 mixt. of an alkylphenol and PhMe reacted with NH3 at 360-400.degree. and 20-80 bar in the presence of an acid catalyst, e.g., Al2O3-SiO2, to give arom. amines. Thus, a 1:2 2-EtC6H4OH-PhMe mixt. was heated to 350.degree. and mixed with a 10-fold excess of NH3 at 38 bar, and the mixt. was passed through a reaction tube contg. 85% SiO2 and 15% Al2O3 at 390.degree. to give a product contg. 50 wt.% 2-EtC6H4NH2, compared to 12% without PhMe. .
