摘要：

The hydrothermal synthesis of CoSAPO-14 and CoSAPO-34 in the presence of isopropylamine as the template is described. CoSAPO-14 is a new MeSAPO material that predominantly forms at 125°C, whereas CoSAPO-34 is the main product at 160°C. CoSAPO-14 has a triclinic and CoSAPO-34 has a trigonal unit cell. Both materials contain in their cavities a template that is hydrogen-bonded to the lattice. The synthesis in the presence of Co2+ ions is much more sensitive to the composition of the reaction gel than is usually found in the preparation of SAPO materials. © 1990.
