摘要:使用甲醇(meoh)进行了卤化镧[lax(3)]衍生物的醇溶化作为降低labr(3)闪烁体生产温度的一种手段的首次研究.最初,通过在室温下简单地将1溶解在meoh中,研究了{[la(micro-Br)(h(2)o)(7)](br)(2)}(2)(1)的脱水.分离出混合的溶剂化物单体[la(h(2)o)(7)(meoh)(2)](br)(3)(2)化合物,其中la金属中心通过与两种其他的meoh溶剂,但必须将内球br转移到外球.为了尝试将1的甲醇中的反应混合物在cah(2)上干燥,分离了[ca(meoh)(6)](br)(2)(3)的晶体.在回流温度下将化合物1溶解在meoh中,导致分离出异常结构,该结构被确定为盐衍生物{[labr(2.75)* 5.25(meoh)](+ 0.25)[labr(3.25)* 4.75(meoh)](-0.25)}(4).最终,通过将干燥的labr(3)溶

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:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.
