摘要
利用微量量热仪测定体系热功率随时间的改变。对于SC(NH2)2-H2O2-Cu2+-OH-封闭体系,测定了不同浓度,不同温度下,体系的单峰振荡行为,得到了不同温度,不同浓度下的振荡周期,并由此计算出振荡反应的表观活化能和反应级数。并得到下列关系:1t∝c-0.
The oscillation reaction in SC SC（NH2）2-H2O2-Cu^2＋-OH^- system was studied on a TAM Air 8-channel calorimeter （Sweden）. From the experimental results, the oscillating periods were obtained. The apparent activation energy and reaction energy and reaction order were calculated. The relations were obtained as follows：1/t∝c1^-0.3355·exp｜-6149.8/T｜.
