摘要
本文采用连续流动装置，结合数学模型方法，测定了油溶性成色剂分别分散在邻苯二甲酸二丁酯（ＤＢＰ）、Ｎ，Ｎ－二乙基十二烷基酰胺（ＤＥＤＡ）和磷酸三丁酯（ＴＢＰ）三种溶剂中的油珠在明胶层中分别与彩色显影剂ＣＤ－２、ＣＤ－３、ＣＤ－４和ＣＤ－６的氧化产物ＱＤＩ２、ＱＤＩ３、ＱＤＩ４、ＱＤＩ６进行偶合反应的比速率常数，研究溶剂对油珠分散状成色剂的反应速率的影响。结果表明，溶剂对偶合反应速率的影响很大，一般来说，ＫＤＢＰ＞ＫＴＢＰ≥ＫＤＥＤＡ。对同一种成色剂而言，它分别与ＱＤＩ２、ＱＤＩ３、ＱＤＩ４和ＱＤＩ６进行偶合反应的比速率常数值可以表征各种显影剂氧化产物的活性。结果还表明，ＱＤＩ２、ＱＤＩ３、ＱＤＩ４和ＱＤＩ６的活性顺序随着成色剂溶剂的不同而不同。本文对上述实验结果进行了分析，并从有组织介质中的反应的角度进行了讨论。
A flow apparatus and a numerical model were used to measure the rate constants of thecoupling reaction of dispersed couplers dissolved in DBP, DEIJA and TBP with 4 QDIs respectively in gelatin layer.The results show that the dispersion solvents have great effect oncoupling kinetics. In general,coupling rate constants decreases in the order KDBP>KTBP> KDEDA, when they were used as a dispersion solvent respectively. The results also show that when dispersion solvent is different , the activity order of 4 QDIs is different. The discussion was given in the view of reaction in organized medium.
