专利号:US-2024075466-A1 优先权日:2021-04-09 标 题:One-Pot Synthesis of Transition Metal-Promoted Chabazites 发明人:VAN TENDELOO LEEN; SCHUETZE FRANK-WALTER; VERHEYEN ELKE JANE JUNE 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.

This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.
专利号:US-4346039-A 优先权日:1981-03-19 标 题 :Synthesis of ochratoxins 发明人:KRAUS GEORGE A 权利人:UNIV IOWA STATE RES FOUND INC 摘要:A simple, direct synthesis route is provided for Ochratoxin compounds, particularly Ochratoxin A, Ochratoxin B, and Ochratoxin C. The reaction involves treating the dimethyl ester of 2-hydroxy-4-methylbenzene-1,3-dioic acid with a deprotonating agent, followed by addition of acetaldehyde, to provide a precursor compound, which can conveniently be converted to Ochratoxins A, B or C. The synthesis route allows for the first time laboratory and industrial scale synthesis of ochratoxins A, B and C in large quantities and pure form making them available as toxins, for use as anti-toxin investigation works, and for biological activity investigations and residue studies.
专利号:WO-2020230156-A1 优先权日:2019-05-10 标题 :A catalyst for one pot synthesis of nabumetone and process of preparation thereof 发明人:YADAV GANAPATI DADASAHEB; PISAL DEVENDRA SHRIRAM 权利人:YADAV GANAPATI DADASAHEB 摘要:The present invention relates to novel heterogeneous catalyst composition for selective synthesis of Nabumetone in one pot process and process to prepare the catalyst. The present invention provides a novel catalyst comprises of Lanthanum, Magnesium, and Nickel particles doped on specific type of silica support, preferably that the support is in amorphous nature. The catalyst is having bifunctional condensation and hydrogenation properties for one pot synthesis of Nabumetone comprising of: Nickel and Lanthanum-magnesium mixed oxide on support of mesoporous silica; Wherein 25 to 30 % w/w of Lanthanum-magnesium mixed oxide are entrapped in pores and surface of support is coated with 3 to 5% w/w Nickel with the result that it prevent the leaching of Lanthanum-magnesium mixed oxide in reaction medium and provides reusability of catalyst.
