Abstract: Berylloaluminosilicates having faujasite structure are described. These beryllium zeolites (Y-zeolites) can have substantially higher Al2O3/SiO2 ratios than the berylliumfree aluminosilicates of similar structure; they can be obtained hydrothermally from aqueous mixtures of the components and can be used instead of the faujasites in industrial processes involving absorption or catalysts.

Abstract: Cpds. (I) of formula CF3(CF2)nSO2F (in which n is 2-14) are produced by electrolysing a mixt. of cpds. (II) of formula CH3(CH2)nSO2F and HF at 4-7.5 V, using 0.3-5 wt.% (II) w.r.t HF. (I) can be used as surfactants, solvents, textile ausiliaries, esp. for water- and oil-proofing, and as starting materials for lubricants, dielectrics and hydraulic fluids.

Abstract: Engine exhaust gases contng. CO and hydrocarbons are burned over catalysts contg. Cu, Zn and Al; the catalyst is prepd. by pptg. as precursor, mixed crystals contng. Cu, Zn and Al, of the malachite, Cu(OH)2.CO3, and/or the Zn5(OH)6.(CO3)2 type, and then decomposing these mixed crystals and converting them into the catalyst. The catalyst has longer life, and high activity at relatively low temp.

Abstract: Melamine is made by heating urea, and/or its thermal decomposition products, at 300-450 DEG C. in the presence of added ammonia or gas containing ammonia and a catalyst comprising aluminium oxide which has been prepared by calcining bohmite, bayerite, hydrargyllite or a mixture thereof at 700-1000 DEG C. The added ammonia may be in the form of the off-gas containing CO2 which is obtained after removing melamine from the reaction gases. The catalyst may be regenerated by treatment with ammonia at elevated temperatures. The process is effected in a continuous manner. The examples relate to a catalyst obtained by calcining a mixture of bohmite and bayerite.
