CRYSTALLINE LAMELLAR ZIRCONIUM PHOSPHATE AND PREPARATION OF LOWER OLEFIN USING SAID COMPOUND AS CATALYST

摘要

PURPOSE:To prepare a lower olefin in high efficiency, by contacting methanol, etc., with a crystalline zirconium phosphate containing organic amine and obtained from a dihydrogen alkyl ammonium phosphate and zirconium oxychloride. CONSTITUTION:A dihydrogen alkyl ammonium phosphate and zirconium oxychloride are subjected to hydrothermal reaction to obtain a crystalline zirconium phosphate of Zr(R3NH)xH2-x(PO4)2.nH2O (X is 0-2; R3N is tertiary organic amine) containing organic amine between layers and having a laminer spacing of >=13Angstrom . A lower olefin can be prepared in high efficiency by contacting methanol or dimethyl ether with the zirconium phosphate prepared by the above process.
