| titleOfInvention | Process for catalytic ring closure of 3-methylpiperidine or 3-methylpyridine by 2-methyl-1,5-diaminopentane |
| abstract | The present invention relates to a process for the preparation of 3-methylpiperidine and 3-methylpyridine on the catalytic ring closure of 2-methyl-1,5-diaminopentane. According to the invention, the gaseous 2-methyl-1,5-diaminopentane is passed through a catalyst, which is activated alumina, aluminum silicon oxide, at a pressure of 300-400 ° C (0-10) × 105 Pa without the addition of ammonia. consisting of either natural or synthetic eneolite, having a ratio of acidic and basic centers on the surface of more than 2 and a specific surface area exceeding 40 m2 / g. If desired, 3-methylpiperidine prepared according to the foregoing is further converted, via dehydrogenation catalyst, into 3-methylpyridine. ŕ |
