摘要:Cha硫属元素化物th(er)4(e = S,Se; R = Ph,C 6 F 5)形成具有多种配位数的吡啶配合物.(py)4 Th(sph)4,(py)3 Th(seph)4,(py)3 Th(sc 6 F 5)4和(py)4 Th(sec 6 F 5)4四种化合物,已通过光谱方法和低温单晶x射线衍射进行了分离和表征.其中两个产品(py)4 Th(sph)4和(py)4 Th(sec6 F 5)4,具有经典的八个坐标a 4 B 4的方形反棱镜几何形状.Seph化合物是唯一的七个坐标(4Se,3N)产物,氟化硫醇盐的独特之处在于该结构在th和氟化物之间包含两个相对的相互作用,从而形成一个九坐标(3N,4S,2F)结构.Eph化合物热分解产生the 2和eph 2,而氟化化合物主要产生thf 4,E 2(c 6 F 5)2和e(c 6 F 5)2.

摘要:A catalyst precursor for use after reductive activation in the conversion of synthesis gas to methanol having formula: CuaThAbOx, wherein A is an alkali metal, a is from 0.1 to 4, b is from 0 to 0.5, and x is a number such that the valence requirements of the other elements for oxygen is satisfied, is prepared by the steps of (I) precipitating at a temperature below 50oC the metals copper and thorium in the form of insoluble thermally decomposable compounds thereof using a precipitant comprising a carbonate and/or bicarbonate of an alkali metal and/or ammonium, the pH being adjusted to a final value in the range from 5.0 to 7.0 (II) recovering the precipitate obtained in step (I), and (III) thermally decomposing thermally decomposable compounds comprised in the precipitate recovered in step (II), the maximum temperature utilised in the thermal decomposition being in the range from 300 to 600oC. Also a catalyst composition of formula Cua.ThO2 wherein a is from 0.1 to 4 and wherein at least 30% of the elemental copper particles are of a size less than or equal to 20 Angstroms.
