摘要
Abstract
Highly pure α-naphthalene sulfonic acid was synthesized through sulfonated technology with naphthalene and gas of SO3 as raw materials by laboratory fal ing film type sulfonated device. The influences of n(SO3)∶n(naphthalene), gas volume fraction of SO3 and reaction temperature on content of α-naphthalene sulfonic acid were investigated.The results showed that the optimum synthesis conditions were as fol ows:n(SO3)∶n(naphthalene)=1.03∶1, the gas volume fraction concentration was 3%, and the reaction temperature was 95℃. The sulfonated conversion rate ofα-naphthalene was 97.6%under the synthesis conditions.关键词
