Abstract
"CATALISADOR PARA USO NA PRODUçãO DE DIALCANOLAMINA PELA REAçãO DE AMÈNIA COM óXIDO DE ALQUILENO E MéTODO PARA A PRODUçãO DO MESMO". fornecido um catalisador produzido pela aminação de um óxido de alquileno com amónia e excelendo em seletividade para uma dialcanolamina. Este catalisador é utilizado na produção de uma dialcanolamina pela reação de amónia com um óxido de alquileno. O catalisador é destinado ao uso na produção de uma dialcanolamina e é caracterizado por ser formado de um metalossilicato e tendo o metalossicilato depositado em um elemento de terras raras de uma quantidade na faixa de 10 - 100% da equivalência de permuta de íon do metalossilicato. Prefere-se, particularmente, que o metalossilicato tenha uma estrutura de MFI e/ou MEL. Consequentemente, o catalisador é capacitado a apresentar seletividade exaltada para dialcanolamina e desfrutar de uma vida de serviço longa."CATALYST FOR USE IN THE PRODUCTION OF DIALCANOLAMINE BY THE REACTION OF AMMONIA WITH ALKYLENE OXIDE AND METHOD FOR THE PRODUCTION OF THE SAME". a catalyst produced by the amination of an alkylene oxide with ammonia and excelling in selectivity for a dialcanolamine is provided. This catalyst is used in the production of a dialcanolamine by reacting ammonia with an alkylene oxide. The catalyst is intended for use in the production of a dialcanolamine and is characterized by being formed of a metallosilicate and having the metallosilicate deposited in a rare earth element in the range of 10 - 100% of the metallosilicate ion exchange equivalence. It is particularly preferred that the metallosilicate has an MFI and / or MEL structure. Consequently, the catalyst is able to exhibit exalted selectivity for dialkanolamine and enjoy a long service life.
