    摘要: Manufacture of methylamines using a catalyst comprising a levynite-type zeolite, especially zeolite Nu-3. In one preferred form of the invention the use of the sodium/hydrogen form of zeolite Nu-3 leads to selective production of monomethylamine (production of both di- and tri-methylamine being depressed). In a further preferred form of the invention the use of the hydrogen form of zeolite Nu-3 achieves selective production of di- and tri-methylamine and suppresses the formation of trimethylamine, the latter being the least in demand commercially of the three methylamines.

    摘要: Deactivation of silica, alumina, silica-alumina and aluminosilicate amination catalysts by coke is inhibited by carrying out the amination reaction in the presence of hydrogen. Alternatively, the coked catalysts may be regenerated in the presence of a stream of hydrogen or of hydrogen and ammonia at somewhat lower temperatures than those commonly used in processes for coke removal by oxidation, thereby reducing the risk of structural damage to the catalyst.

    摘要: A process for the manufacture of methylamines comprises reacting a feed comprising methanol and/or dimethylether and ammonia over a binderless zeolite A catalyst, preferably a binderless zeolite 5A catalyst. Use of binderless zeolite 5A makes the process attractively selective to dimethylamine in preference to mono- and tri- methylamine. In addition, if the catalyst is essentially free of alkali metal it is not only more active than similar catalysts containing alkali metal but also considerably more selective.
