| Abstract: | An improved method for synthesizing a new type of highspeed-diazo-sensitiser,known as 2,5-diethoxy-4-morpholinobenzediazonium sulfate,was presented.Compared with the previous research work,it is a simpler,more reasonable,and more effective method,using hydroquinone as the basic material to be subjected by a series of reactions,such as halogenation,nitration,displacement,reduction,and diazotization.The target molecules were obtained with a comparatively high yield(equating to 33.5%) and good quality.This kind of compound is characterized by a high-speed photosensitivity,good compatibility,remarkable contrast,good stability and security. |
