对乙酰氨基酚-KBrO3-H2SO4体系化学振荡反应的研究
A Study of the Chemical Oscillation in the p-Acetamidophenol—Bromate—Sulfuric Acid System
【摘要】 本文主要研究在CSTR(连续搅拌反应器)条件下一些因素对化学振荡的影响,得到该非催化振荡的最佳条件和振荡范围,以及反应总活化能。BZ型反应催化剂对非催化振荡有不同的影响。本文发现除Mn2+,Ce3+之外,{Fe(phen)3}2+也能使停振的非催化振荡复活。当BZ催化剂加入到非催化振荡体系中。整个体系转变成非催化和催化振荡的藕合体系。实验事实说明:非催化振荡的有机产物是随后催化振荡反应物。在CSTR中利用铂电极和分光光度计同时检测出{Fe(phen)3}2+的振荡行为。
【Abstract】 The factors affecting the oscillatory behavior in a CSTR (continous stirred tank reactor) have mainly been investigated in this paper and optimum and boundary conditions and active energy for this uncatalyzed chemical oscillation are obtained. BZ catalysts have different effects on uncatalyzed oscillations. It has been found that {Fe(phen)3}2+ (such as Mn2+, Ce3+) also reinitiates the exhaused uncatalyzed system, the whole system changes into an uncatalyzed and catalyzed couping oscillatory system. It has been identified that the product of uncatalyzed reaction is a reactant of following catalyzed oscillation. In the CSTR, Pt electrode and spectrophotometer are used to show instantaneously the oscillatory behaviors of {Fe(phen)3}2+
