| titleOfInvention | Aniline-into-diphenylamine condensation catalyst solution and method of preparation thereof |
| abstract | FIELD: organic synthesis catalysts. SUBSTANCE: catalyst solution contains 1.6 to 98.6% of aniline, water (0.4-12.4%) and, as active constituent, hydroxytrifluoroboric acid anilinium salt (1.0- 36.0%). When preparing composition, ortoboric acid is first dissolved in hydrofluoric acid, after which aniline is added at stirring. EFFECT: simplified preparation procedure. 2 cl, 6 ex |
