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 method for the continuous synthesis of a substituted benzoic-acid organic substance. The continuous synthesis method comprises: in the presence of catalyst and organic solvent, the organic matter represented by formula (I) and oxygen are continuously inputted to a continuous reaction apparatus for continuous oxidation reaction to obtain a substituted benzoic-acid organic substance, which is discharged continuously, the substituted benzoic-acid organic substance having the structure represented by formula (II). Oxygen is a green reagent and is inexpensive and readily available; a large amount of wastewater, waste gas, and solid waste is not generated after the reaction, and the system is easy to handle. The use of a continuous reaction operation can reduce the risk of flash distillation and explosion of solvent due to a high concentration of oxygen in a batch reaction. Under the same oxidation conditions, the continuous preparation process can reduce the escape of oxygen, greatly increasing the oxygen utilization rate and also simplifying the operation, improving the safety of the reaction and the yield of the substituted benzoic-acid organic substance.

摘要:The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.

权利人:STUDIENGESELLSCHAFT KOHLE MBH
摘要:Process for reacting an H-acidic organic compound, in which the acidic H-atom is bonded to the organic radical by an oxygen or a sulphur atom, e.g. an alcohol, with a metal having a standard potential which is more positive than -1.66 volts and which at most incompletely reacts with the H-acidic compound under current-free conditions, e.g. Ni, Co, Fe, Mn, Sb, Cu, or Au. The H-acidic compound or a solution thereof is a polar solvent is made conducting by addition of a soluble salt of chlorine, bromine or iodine, and is electrolyzed at a temperature of up to 150° C, using said metal as the anode, for production of the alcoholate.
