PURPOSE:To obtain a zeolite compsn. useful as a novel catalyst by allowing an aq. mixture contg. sparingly water-soluble alumina source, silica source, and phosphate source, together with org. amine or quat. ammonium ion to cause hydrothermal reaction. CONSTITUTION:An aq. mixture contg. sparingly water-soluble alumina source, silica source, and phosphate source together with an org. amine or a quat. ammonium ion is prepd. The aq. mixture is charged in an autoclave and heated to cause hydrothermal reaction. Crystalline aluminophospho silicate is obtd. by filtering the reaction liquid. The principal powder X-ray diffraction peaks of the zeolite compsn. are given in Table 1 and 2. The zeolite compsn. is suited as catalyst for reactions requiring shape selectivity, such as prepn. of dialkyl benzene compds., synthesis of hydrocarbon from methanol, etc. |
