彩色显影剂CD-4的合成方法研究

Study on synthetic methods of color developing agent CD-4

以N乙基间苯甲胺为主要原料，通过羟乙基化、亚硝化、还原和成盐等步骤得到性能合格的成品，合成彩色显影剂CD4，总收率达到60%以上。

Qualified color developing agent CD 4 , 3 methyl 4 amino N ethyl N (β hydroxyethyl ) aniline sulfate , is synthesized by hydroxyethylation , nitrosation , reduction and salt forming using 3 methyl aniline as raw material . The total product yield can reach over 60 % .

本文还分别测定了彩色显影剂CD-2和CD-4的氧化产物在明胶层中的扩散系数以及它们分别与水溶性成色剂WC-1的偶合反应的速率常数。

This combination of experiments with the given model has been used to find the diffusion coefficient of QDI and the rate constant of the coupling reaction in the gelatin layer .

彩色显影剂粒化方法研究

A research on the methods of colour developer agglomeration

本文介绍彩色显影剂的造粒方法，并对我国实现彩色显影剂的粒化提出建议。

This paper introduces the methods of colour developer agglomeration and makes a suggestion about the granulation of colour developer in China .

染料型黑白胶片上的画面影像纯粹是由彩色成色剂与通常的彩色显影剂偶合反应生成的染料所构成的，类似于彩色胶片，因此这种胶片可以在任何地方的冲洗店进行冲洗，极为方便。

Like color films , the picture image formed on dye type black and white film is composed purely of dyes resulted from the coupling reaction of color couplers with conventional color developing agent , thus this kind of films can be easily processed in normal photo laboratories anywhere .
