Resumo: The improvement of the structure of the ZSM-12 zeolite has been extensively studied, due to its shape selectivity properties, acidity and hydrothermal stability, with this zeolite being used in a wide range of applications, such as adsorbent, ion exchanger and in important reactions in the petrochemical area. In this work, the effect on the crystallization characteristics and physicochemical properties of the ZSM-12 zeolite using methyltriethylammonium chloride, individually, and combined with n-butylamine, as structure-directing agent was studied. The syntheses were carried out at 160 and 170 °C between 48 and 144 h in static medium. The samples obtained were characterized by the techniques of X-ray diffraction, thermal analysis, nitrogen adsorption-desorption and temperature-programmed ammonia desorption. The simultaneous use of methyltriethylammonium chloride and n-butylamine, at a ratio of 0.2, promoted the obtainment of highly crystalline ZSM-12, with an increase in the microporous area and acidity, denoting an improvement in the physicochemical properties of this zeolite.

Esta zeolita se utiliza en una amplia gama de aplicaciones, como adsorbente, intercambiador de iones y en reacciones importantes. en el área petroquímica. En este trabajo se estudió el efecto sobre las características de cristalización y propiedades fisicoquímicas de la zeolita ZSM-12 utilizando cloruro de metiltrietilamonio, individualmente y combinado con n-butilamina, como agente director de estructura. Las síntesis se realizaron a 160 y 170 °C entre 48 y 144 h en medio estático. Las muestras obtenidas se caracterizaron mediante las técnicas de difracción de rayos X, análisis térmico, adsorción-desorción de nitrógeno y desorción de amoniaco programada por temperatura. El uso simultáneo de cloruro de metiltrietilamonio y n-butilamina, en una proporción de 0,2, promovió la obtención de ZSM-12 altamente cristalino, con aumento del área microporosa y acidez, lo que denota una mejora en las propiedades fisicoquímicas de esta zeolita.O aprimoramento da estrutura da zeólita ZSM-12 vem sendo extensivamente estudado, devido às suas propriedades de seletividade de forma, acidez e estabilidade hidrotérmica, sendo esta zeólita utilizada em uma ampla gama de aplicações, tais como adsorvente, trocador iônico e em importantes reações na área petroquímica. Neste trabalho o efeito sob as características da cristalização e das propriedades físico-químicas da zeólita ZSM-12 utilizando o cloreto de metiltrietilamônio, individualmente, e combinado com n-butilamina, como agente direcionador de estrutura foi estudado. As sínteses foram realizadas a 160 e 170 °C entre 48 e 144 h em meio estático. As amostras obtidas foram caracterizadas pelas técnicas de difratometria de raios X, análises térmicas, adsorção-dessorção de nitrogênio e dessorção de amônia a temperatura programada. A utilização simultânea do cloreto de metiltrietilamônio e n-butilamina, na razão 0,2, promoveu a obtenção da ZSM-12 altamente cristalina, com incremento da área microporosa e acidez, denotando uma melhoria das propriedades físico-químicas desta zeólita.Research, Society and Development2022-01-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2540210.33448/rsd-v11i1.25402Research, Society and Development; Vol. 11 No. 1; e54311125402Research, Society and Development; Vol. 11 Núm. 1; e54311125402Research, Society and Development; v. 11 n. 1; e543111254022525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25402/22168Copyright (c) 2022 Elisa Gabriela Costa Gouveia; Soraya Lira Alencar; Bruno José Barros da Silva; Maritza Montoya Urbina; Julyane da Rocha Santos Solano; Antonio Osimar Sousa da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGouveia, Elisa Gabriela CostaAlencar, Soraya LiraSilva, Bruno José Barros daUrbina, Maritza MontoyaSolano, Julyane da Rocha SantosSilva, Antonio Osimar Sousa da2022-01-16T18:08:18Zoai:ojs.pkp.sfu.ca:article/25402Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:41.631713Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
