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 relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

标题:Method for catalytic synthesis of ammonia under normal pressures
发明人:GUAN XIAOFEI; TANG ZUJIAN
权利人:UNIV SHANGHAI TECHNOLOGY
摘要:A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal reacts with the nitrogen to produce the metal nitride, and the molten salt provides a new reaction interface for the metal nitride to react with the hydrogen to synthesize ammonia, so that ammonia is produced continuously. In addition, the molten salt prevents the liquid alloy from contacting with the oxygen and the water vapor, which prevents the liquid alloy from being oxidized, thus prolonging its service life.

标 题:Method for enzymatic synthesis of oligonucleotides using phosphate precipitation
发明人:HYMAN EDWARD D
摘要:Enzymatic synthesis of a portion of an oligonucleotide is performed by a cycle of synthetic steps: (a) combining an oligonucleotide primer and a blocked nucleotide in a reaction mixture in the presence of a chain extending enzyme, such that a primer-blocked nucleotide product is formed, wherein the blocked nucleotide substrate comprises (i) a nucleotide to be added to form part of the defined sequence and (ii) a blocking group attached to the nucleotide effective to prevent the addition of more than one blocked nucleotide to the primer; and (b) removing the blocking group from the 3' end of the primer-blocked nucleotide product to form a primer-nucleotide product. Phosphate is generated in at least one synthetic step. A precipitate is formed in the cycle comprising phosphate and at least one precipitation cation. The precipitation of phosphate reduces its unfavorable effect on the method. Preferably, cycles of the method are repeated without intermediate purification of primer-nucleotide product or precursor. The precipitation cation may be a polyvalent elemental cation, spermine, or a cation which forms a poorly soluble salt with phosphate. Preferably, the chain extending enzyme is RNA Ligase, the blocked nucleotide is AppNp, and the blocking group is removed using a phosphatase. There is also provided a method for reducing the inhibitory effect of nucleoside 5'-monophosphate and of 3',5'-nucleoside diphosphate on phosphodiesterase I. This is accomplished by enzymatically converting these inhibitors to less inhibitory products.
