In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of SAPO-56 molecular sieve and its catalytic performance in methanol-to-olefins reaction, published in 2020, which mentions a compound: 111-18-2, mainly applied to SAPO 56 zeolite catalytic methanol olefin, Category: thiazole.
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.
Compounds in my other articles are similar to this one(N1,N1,N6,N6-Tetramethylhexane-1,6-diamine)Category: thiazole, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
