KRISTALLINES ALUMOSILIKAT, VERFAHREN ZU SEINER HERSTELLUNG UND VERWENDUNG

摘要

The crystalline aluminosilicate PZ 1 is produced by carrying out the crystalline in the presence of an organic template compound of the formula R3P-(CH2)n-PR3X2 where R is a lower alkyl group, n is an integer of 2 to 6 and X is Br- or I-. The synthesis mixture has the composition: -SiO2/Al2O3 = 20-250 -Na2O/SiO2 = 0.01-0.5 -OH/SiO2 = 0.01-1.0 -T/SiO2 = 0.01-0.2 -H2O/SiO2 = 10-40 - whereas T means template compound. The synthesis mixture is stirred at a temperature between 90 DEG and 200 DEG C. at autogenous pressure. The aluminosilicate PZ 1 is changed into the aluminosilicate PZ 2 by treatment with dilute acids or with ammonium chloride and subsequent calcining. This aluminosilicate PZ 2 can be employed as catalyst in the conversion of alcohols into hydrocarbons.
