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:A rare earth metal extractant in the form of a dialkyl diglycol amic acid is synthesized by reacting diglycolic anhydride with a dialkylamine in a synthesis medium. A molar ratio (B/A) of dialkylamine (B) to diglycolic anhydride (A) is at least 1.0. A non-polar or low-polar solvent in which the dialkyl diglycol amic acid is dissolvable is used as the synthesis medium.

摘要:Random or block co- or terpolymers produced by using metal complex catalysts in a reaction of one conjugated diene monomer with one aromatic Random or block co- or terpolymers produced by using metomers with one aromatic α-olefin or terpolymers of one conjugated diene monomer with one aromatic α-olefin and one aliphatic α-olefin by using metal complexes comprising metals of group 3 to 10 of the Periodic System of the Elements in combination with activators and optionally a support material. More particularly the metal complexes used for the synthesis of co- or terpolymer are lanthanide metals. Even more particularly diene monomer(s) and aromatic α-olefin monomer(s) such as, but not limited to, butadiene and styrene or isoprene and styrene are copolymerized giving random or block copolymers or butadiene, styrene and isoprene are terpolymerized giving random or block terpolymers using metal complexes comprising lanthanide metals in combination with activators and optionally a support material. Preferably random co- or terpolymers are formed.
