A rapid gravimatric method for the simultaneous microdetermination of carbon, hydrogen and molybdenum (or zinc) in organometallic compounds

Abstract

Binuclear and trinuclear Mo-contg. compounds were covered with 20-fold WO3 and were ignited at 520-790癈 for C, H, and Mo determination In the presence of WO3, the loss of the volatile residue MoO3 was prevented. A Zn-contg. compound was also analyzed by covering the sample with 20-fold WO3 and ignited at >660癈. In the presence of WO3, Zn was oxidized completely to form ZnWO4. The method is simple and accurate. The anal. rate is 15 min per anal.

Key words: ZINC, MICRO ANALYSIS, HYDROGEN, MOLYBDENUM, RAPID ANALYSIS, THERMOLYSIS, CARBON, CLUSTER COMPOUND, ORGANOMETALLIC COMPOUNDS, SIMULTANEOUS DETERMINATIONS, TUNGSTEN OXIDE, BLANKETING(EFFECT)
