以萘和SO3为原料,利用试验室降膜式磺化装置,通过气相-SO3磺化工艺,合成高纯度α-萘磺酸.考察了n(SO3)∶n(萘)、气相SO3的体积分数、反应温度对α-萘磺酸含量的影响.结果表明α-萘磺酸最佳合成工艺条件为：n(SO3)∶n(萘)=1.03∶1,SO3的体积分数为3%,反应温度为95℃,在该条件下萘的转化率可达97.6%.

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.
