| Abstract: | Naphthalene disulfonic acid has been synthesized by treating naphthalene with oleum of 1,2dichloroethane and the factors affecting the reaction have been investigated. It is shown that when using 30% oleum as sulfonation agent under the conditions of n(naphthalene)∶n(SO 3)=1∶2.25, the reaction temperature of 5 ℃, the reaction time of 8 h, the yield of 1,5Naphthalene disulfonic acid is 76.5%. |
