Differences in Al distribution and acidic properties between RTH-type zeolites synthesized with OSDAs and without OSDAs was written by Liu, Ming;Yokoi, Toshiyuki;Yoshioka, Masato;Imai, Hiroyuki;Kondo, Junko N.;Tatsumi, Takashi. And the article was included in Physical Chemistry Chemical Physics in 2014.Application of 79-55-0 This article mentions the following:
In addition to the original preparation route of the RTH-type zeolites using 1,2,2,6,6-pentamethylpiperidine (PMP) as an organic structure directing agent (OSDA), simpler organic amines such as N-methylpiperidine and pyridine can be used as alternative OSDAs in place of PMP. Also, the authors established a synthesis method for preparing the RTH-type zeolites without using any OSDAs. RTH-type aluminosilicates were synthesized with different types of OSDA or without using any OSDAs. The obtained zeolites synthesized with different preparation methods were characterized by using various techniques, especially high-resolution 27Al MASNMR and in situ FTIR techniques using CO adsorption. The relation between the preparation method and the catalytic performance in the methanol to olefins (MTO) reaction was discussed. Finally, the distribution of Al species in the RTH-framework was clarified. In the experiment, the researchers used many compounds, for example, 1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0Application of 79-55-0).
1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0) belongs to piperidine derivatives. Piperidine is a saturated organic heteromonocyclic parent, an azacycloalkane, a secondary amine and a member of piperidines. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.Application of 79-55-0
