本文对氧化锌和氯化铵的反应动力学试验研究结果表明,氧化锌和氯化铵的反应:ZnO_(s)+2NH_1Cl=Zn(NH_3)_2Cl_2+H_2O系一分数级反应,其速度方程为:v=k[NH_4Cl]~(1,6)温度在328K 以下,反应属于化学反应控制。活化能 E_α为47.88KJ·mol~(-1)。lgk=(-2500/T)+3.46;温度在328K 以上,过程转化为扩散控制。活化能 E_α~′为9.58KJ·mol~(-1)。lgk=(-500/T)-2.65。化学分析和 X-射线衍射分析确证了反应产物为二氯二氨合锌 Zn(NH_3)_2Cl_2。
The reaction kinetics of zinc oxide and ammonium chloride in this paper shows that the reaction of zinc oxide with ammonium chloride is one-order reaction of ZnO_ (s) + 2NH_1Cl = Zn (NH_3) _2Cl_2 + H_2O with velocity equation : v = k [NH_4Cl] ~ (1,6) temperature below 328K, the reaction belongs to the chemical reaction control. The activation energy E_α is 47.88 KJ · mol -1. lgk = (- 2500 / T) +3.46; the temperature is above 328K, the process is converted to diffusion control. The activation energy E_α ~ ’is 9.58KJ · mol ~ (-1). lgk = (- 500 / T) -2.65. Chemical analysis and X-ray diffraction analysis confirmed that the reaction product was Zn (NH 3) 2 Cl 2.
