Abstract: Cr silicate has a zeolite structure and is prepd. by crystallisation from a mixt. of water glass and an aq. soln. of amine at a temp. 100-200 degrees C, under soln. pressure, and in the presence of Cr(III) oxide and/or Cr(III) hydroxide. Pref. the zeolite is prepd. using a mixt. of water glass (25-30wt.% SiO2, 8wt.% Na2O) and Cr nitrate, -sulphate, or -chloride. A Cr(III) silicate gel is also suitable. To the mixt. is added 5-50wt.% (10-25wt.%) hexamethylenediamine. The mixt. is heated for 2-4 days at 140-160 degrees C. The resultant Cr silicate has a zeolite structure but contains only a small amt. of Al. The prod. contains 0.5-3wt.% Cr2O3. Crystalline Cr silicate zeolite belongs to the ZSM-5 type and is suitable as catalyst, after activation, in cracking and hydro-cracking processes and in teh conversion of methanol into unsatd. hydrocarbon.

Abstract: 'Defect-zeolites' (contg. tetrahedral voids filled with H2O and protons) are produced by selectively removing beryllium from alkali beryllo-alumino-silicates having a faujasite structure (zeolite Y), in which the molar ratio SiO2:al2O3. is 5:1 to 10:1, by treatment with aq. solns. having pH 3.0-5.5 (the soln. may contain buffer substances). The 'defect-zeolites' are used instead or ordinary aluminosilicate zeolites for adsorption or catalysis in cases when improved temp. stability and increased adsorption or catalysis in cases when improved stability and increased adsorption capacity required. After the removal of beryllium, there remains excess SiO2 with respect to Al2O3 (compared with the aluminosilicate zeolites), whereby the acid resistance of the product is also improved. The process results also in an increased average, lattice constant, whereby adsoption is promoted. The crystallinity of the product is not affected otherwise.

Abstract: New crystalline As silicate (I) has zeolite structure. (I) is produced by heating SiO2 and As2O3 in an aq. hexamethyl-enediamine (II) soln. at 100-200 degrees C under autogenous pressure and crystallisation. (I) is useful as catalyst in hydrocarbon conversions, esp. in the conversion of MeOH (or Me2O) to (2-4C) olefins.
