权利人:UMICORE AG & CO KG
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.

摘要:The present invention provides a catalyst for asymmetric synthesis prepared from a dialkali metal salt of an optically active 2,2'-dihydroxy-1,1'-binaphthyl represented by the formula (IR) (IR) or the formula (IS) (IS) (wherein M is Li, K or Na), a lanthanum compound represented by LaX3 (X is F, Cl, Br, I, NO3 or CH3CO2) and an alkali metal alkoxide or an alkali metal hydroxide represented by MOR or MOH (M is Li, K or Na, and R is isopropyl or t-butyl), respectively, in the presence of a water-containing solvent. The catalyst of the present invention is extremely valuable as a catalyst for asymmetric synthesis of an asymmetric nitroaldol reaction useful in the synthesis of a beta -hydroxynitro compound which is an important synthetic raw material for an optically active compound such as a medicine.

标 题 :Process for production of solution-derived (Pb,La)(Nb,Sn,Zr,Ti)O3 thin films and powders
发明人：BOYLE TIMOTHY J
权利人:SANDIA CORP
摘要:A simple and rapid process for synthesizing (Pb,La)(Nb,Sn,Zr,Ti)O 3 precursor solutions and subsequent ferroelectric thin films and powders of the perovskite phase of these materials has been developed. This process offers advantages over standard methods, including: rapid solution synthesis (<10 minutes), use of commercially available materials, film production under ambient conditions, ease of lanthanum dissolution at high concentrations, and no heating requirements during solution synthesis. For lanthanum-doped ferroelectric materials, the lanthanum source can be added with total synthesis time less than 10 minutes. Films and powders are crystallized at approximately 650° C. and exhibit ferroelectric properties comparable to films and powders produced by other techniques which require higher crystallization temperatures.
