催化剂二丁基二硫代氨基甲酸钼的合成及表征

Synthesis and characterization of catalyst of molybdenum dibutyldithiocarbamate

采用“一锅法”制备催化剂二丁基二硫代氨基甲酸钼,研究了原料的最佳配比及工艺条件参数,通过FTIR、1H NMR、元素分析等表征结构。结果表明,合成该催化剂的最佳反应条件:物料摩尔比为三氧化钼∶硫化钠∶硫酸∶二丁基二硫代氨基甲酸钠为1∶1.4∶1.6∶1,反应温度110℃,反应时间4 h。

The catalyst molybdenum dibutyl dithiocarbamate was synthesized by one-pot method.The optimum ratio of experimental raw materials and technological parameters were studied,and the structure was characterized by FTIR,1H NMR and elemental analysis.The result showed that the best synthetic conditions were that molybdenum trioxide∶sodium sulfide∶sulfuric acid∶sodium dibutyl dithiocarbamate were 1∶1.4∶1.6∶1,the reaction temperature was 110℃and reaction time was 4 h.
