摘要: 采用实验与数学模拟相结合的方法,研究了明胶层中释放显影抑制剂型成色剂与彩色显影剂氧化产物(QDI)的反应动力学,由实验测量的反应动力学结果与模拟动力学结果基本吻合,证明了明胶层中释放显影抑制剂型成色剂与QDI的反应,主要是发生在油-水界面上,反应速率与油珠大小、比速率常数、成色剂在油相中的浓度以及QDI的扩散系数有关。通过数值分析得到明胶层中DIR(Ⅰ)和DIAR(Ⅱ)分别与QDI反应的表观速率常数和比速率常数。

Abstract: A conbination of flow-apparatus and a numerical model for simulating diffusion with a reaction on intersurface of droplets which were dispersed in a gelatin layer was employed for investigating the kinetic process of the reaction of dispersion DIR(Ⅰ)and DIAR(Ⅱ) coupler with QDI respectively in gelatin layer. The results showed that the kinetic curves obtained from both the experiments and the numerical model were in good agreement.This suggested that the reaction took place dominantly at the interface between droplets and gelatin-aqueous solution and that the reaction rate was dependent on the size of droplets, specific rate constant, concentrations of coupler in the organic medium and of QDI on the intersurface of droplets, which was also related to the diffusion coefficient of QDI in the gelatin layer. The specific rate constants of reaction of DIR(Ⅰ) and DIAR(Ⅱ)coupler with QDI were obtained respectively.
