The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Synthesis of SAPO-56 molecular sieve and its catalytic performance in methanol-to-olefins reaction》. Authors are Du, Yicun; Zhao, Yu; Liu, Hongxing.The article about the compound:N1,N1,N6,N6-Tetramethylhexane-1,6-diaminecas:111-18-2,SMILESS:CN(C)CCCCCCN(C)C).Reference of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine. Through the article, more information about this compound (cas:111-18-2) is conveyed.
The synthesis of SAPO-56 mol. sieves with different Si contents was carried out by the method of low-high temperature multistep crystallization using N, N, N′, N′-tetramethyl-1, 6-hexanediamine (TMHD) as template. The samples were characterized by X-ray diffraction (XRD), SEM (SEM), N2 adsorption-desorption, NH3 temperature programmed desorption (NH3-TPD) and evaluated their catalytic performances in the conversion of methanol-to-olefins reaction (MTO). The results indicated that the morphol. of the samples changed greatly, especially the sample with the ratio of SiO2/Al2O3 0.4 appeared new sandwich layered structure. And the surface acidity increased with the increase of the ratio of SiO2/Al2O3. Moreover, the selectivity of olefins increased primarily and then decreased. The highest olefins selectivity was appeared when the ratio of SiO2 to Al2O3 was 0.4.
