研究了用V~(5+)作主催化剂,在低酸度下用氯酸钠使联二脲氧化成偶氮二甲酰胺反应中,催化剂钒、溶液的酸浓度以及反应温度等因素对反应的影响,生成偶氮二甲酰胺的速度对催化剂V~(5+)以及当反应溶液中〔H~+〕在0.29mol/L与0.66mol/L之间时对〔V~(5+)〕与〔H~+〕均呈二级反应。根据实验数据,提出了反应的可能机理,解释了实验结果,同时指出反应的较佳条件及实现催化剂循环使用的必要因素。 The effect of vanadium on the acidity of the catalyst and the reaction temperature during the oxidation of bisurea to azodicarboxamide with sodium chlorate at a low acidity was studied by using V ~ (5+) as the main catalyst. , The rate of the formation of azodicarbonamide to the catalyst V ~ (5+) and to [V ~ (5+)] when the concentration of [H ~ +] in the reaction solution is between 0.29 mol / L and 0.66 mol / L And [H ~ +] were secondary reaction. Based on the experimental data, the possible mechanism of the reaction is proposed, the experimental results are explained, the optimum conditions of the reaction and the necessary factors for the catalyst to be recycled are also pointed out.
