摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

权利人:RHONE POULENC CHIMIE
摘要:The process for cleaving the heavy by-products derived from the synthesis of alkylchlorosilanes, in particular C1 to C6 alkylchlorosilanes, more particularly methylchlorosilanes, in particular for the cleavage of alkylchlorodisilanes, in particular methylchlorodisilanes having from one to five chlorine atoms, is carried out by treatment with hydrochloric acid in the presence of a catalytic system which comprises at least one metal phosphate, preferably associated with a basic impregnation compound. The metal phosphate may in particular correspond to the formula: M(XPO4)y in which M represents a metal chosen from: monovalent metals, in which case X is 2H and y=1 divalent metals, in which case X is H and y=1 trivalent metals, in which case X is absent and y=1 tetravalent metals, in which case X is: H and y=2 pentavalent metals, in which case X is 0 and y=1.
