在前文研究工作的基础上,较详细地研究了DL-苹果酸(以下简称DL-MA)、丙酮(以下简称Act)参与下的新型化学振荡反应及各种影响因素,对各主要参与反应物质在诱导期中的作用、起振原因、诱导期的新特征和可能反应机理进行了较为深入的研究,分别获得DL-MA,KBrO_3,MnSO_4的浓度对诱导期影响的拟合方程t_(IN)(C_(DL-MA))=-0.051+0.096/(C_(DL-MA)-0.181)(有Act存在时)t_(IN)(C_(DL-MA))=-0.24+0.224/(C_(DL-MA)-0.0485)(无Act存在时)t_(IN)(C_(KBrO_3))=73.429C_(KBrO_3)+1.275t_(IN)(C_(MnSO_4))=99.5c_(MnSO_4)+4.2(式中t_(IN)表示诱导期,C_(DL-MA),C_(KBrO_3),C_(MnSO_4)分别表示DL-MA,KBrO_3,MnSO_4的浓度)以及诱导期的表观活化参数为E_(IN)=68.50kJ·mol~(-1).
Based on the previous research work, the new chemical oscillatory reactions involving DL-malic acid (hereinafter referred to as DL-MA) and acetone (hereinafter referred to as Act) and various influencing factors were studied in detail. In the induction period, the causes of excitation, the new characteristics of the induction period and the possible reaction mechanism were studied in depth. The fitting equations of the effects of DL-MA, KBrO_3 and MnSO_4 on the induction period t_ (IN) ( C_DL-MA = - 0.051 + 0.096 / C DL-MA -0.181 when there is an Act t_ IN - C DL - MA = -0.224 + 0.224 / C_ DL-MA) -0.0485) (without Act) t_ (IN) (C_ (KBrO_3)) = 73.429C KBrO_3 + 1.275t_INC_ MnSO_4 = 99.5c MnSO_4 +4.2 In the formula, t IN represents the concentration of DL-MA, KBrO_3 and MnSO_4, and C_ (DL-MA), C_ (KBrO_3) and C_ (MnSO_4) ) = 68.50 kJ · mol -1.
