A highly crystalline new precursor of CHA-type zeolite AlPO4-34 was obtained by using an aluminophosphate gel with a chiral diamine [(S)-(+)-1-(2-pyrrolidinylmethyl)pyrrolidine; C9H18N2] as an organic structure directing agent under hydrothermal synthesis conditions. This precursor (called GAM-1) was changed into the zeolite AlPO4-34 which had a high porosity (the Brunauer-Emmett-Teller (BET) surface area is approximately 700 m3 g-1) using calcination. The GAM-1 obtained was characterized by various measurements, e.g., powder X-ray diffraction, scanning electron microscopy, and solid-state nuclear magnetic resonance spectroscopy, and so on. Structure determination from powder diffraction data revealed that the new precursor GAM-1 has triclinic symmetry [space group P1, a = 9.16535(11) A, b = 9.23042(11) A, c = 9.29228(11) A, alpha = 79.8243(7), beta = 87.4593(7), gamma = 86.5365(7)] and the chemical formula was estimated to be: Al6P6O24H2F2(C9H18N2)·2.5(H2O). It also revealed that a two edge sharing AlO4F2 octahedron with an Al-F-Al bridge was included in the framework. GAM-1 was transformed into AlPO4-34 with rhombohedral symmetry (R3) by elevating temperature to over 400 C. At high temperatures, AlO4F2 octahedron connectivity was changed into an AlO4 tetrahedron. The crystal structure of the dehydrated AlPO4-34 changed back to a triclinic symmetry (P1) model again after rehydration in the atmosphere.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 51207-66-0 is helpful to your research. Electric Literature of 51207-66-0
