【Abstract】 High efficiency chemiluminescent material bis(6-(3’-methylbutoxycarbonyl)-2,4-dichlorophenyl)oxalate was synthesized from oxalyl chloride and 3,5-dichlorosalicylate obtained by esterifying the 3,5-dichlorosalicylic acid, which was prepared by chlorinating salicylic acid, with isopentanol. These compounds were synthesized conveniently with available materials and yield of bis(6-(3’-methylbutoxycarbonyl)-2,4-dichlorophenyl)oxalate was 84%. The mechanism of chemiluminescent was studied . The results showed that the intensity was strong and lifetime was long as the concentration of peroxide was 0.61‰～1‰ more than that of oxalate.更多还原
