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.

标 题:Synthesis and purification of CBDA

摘要:Methods and systems for the preparation of high purity and high quality cannabinoid acids and metal salts of cannabinoids. Cannabidiolic acid (CBDA) is a major cannabinoid of interest for and health reasons. It is the natural precursor of cannabidiol (CBD). The invention provides methods for the synthesis of CBDA from CBD with reagents that produce a high purity product without need for further purification. Insertion of a magnesium complexing agent prior to conversion of the reaction intermediate to the final acid product produces a high purity product with aesthetically pleasing white color and neutral odor. Methods are provided for the simultaneous synthesis and purification of cannabinoid acids, especially CBDA, produced from high purity CBD (or other cannabinoid) via a Kolbe-Schmitt type reaction using an organic base, such as DBU (1,8-diazabicyclo[5.4.0]undec-7-ene), incorporating complexation of acid anions to a multivalent metal, alkaline earth or transition metal, prior to product acid work-up. During the work-up to the final acid, the distinct solubility of the complex in selected solvents is used advantageously to first exclude water soluble reagents and impurities and next to exclude lipophilic hydroxyl-quinone impurities, as well as any unconverted CBD.

摘要:At the time of synthesis of lithium nickelate, by adding a firing aid to material to be fired, crystal growth is promoted at a temperature that is lower than a firing temperature necessary for obtaining desired crystal growth of lithium nickelate, and substitution of elements that contribute to structural stability in crystals is promoted. Furthermore, distortion of crystal or loss of oxygen at the time of synthesis is suppressed. Thus, a lithium ion secondary battery having excellent charge and discharge characteristics and cycling characteristics can be provided.

摘要:A method of SrCu 2 O 2 spin-on precursor synthesis and low temperature p-type thin film deposition, includes preparing a wafer to receive a spin-coating thereon; selecting metalorganic compounds to form a SrCu 2 O 2 precursor, mixing and refluxing the metalorganic compounds to form a precursor mixture; filtering the precursor mixture to produce a spin-coating precursor; applying the spin-coating precursor to the wafer in a two-step spin coating procedure; baking the spin-coated wafer using a hot-plate bake to evaporate substantially all of the solvents; and annealing the spin-coated wafer to form a SrCu 2 O 2 layer thereon in a two-step post-anneal process.

摘要:Described herein are catalyst support materials for use in synthesizing ammonia (NH 3 ) from nitrogen gas (N 2 ) and hydrogen gas (H 2 ) and methods of making the same. The support material may comprise (MgO) x (BaO) y (Al 2 O 3 ) z and/or (MgO) x (SrO) y (Al 2 O 3 ) z , on which an ammonia synthesis catalyst such as ruthenium is dispersed. When the catalyst support material comprises (MgO) x (BaO) y (Al 2 O 3 ) z , x is from about 0.05 to about 0.7, y is from about 0.05 to about 0.6, and z is from about 0.3 to about 0.5. When the catalyst support material comprises (MgO) x (SrO) y (Al 2 O 3 ) z , x is from about 0.4 to about 0.7, y is from about 0.05 to about 0.5, and z is from about 0.05 to about 0.3.
