摘　　要：对采用液体SO3为磺化剂合成β-萘磺酸的新方法进行了研究。结果显示,如果能够有效解决液体SO3与萘的快速混合分散以及反应热的移去等问题,则通过该方法能够得到高产率的β-萘磺酸。对磺化反应条件及异构化反应条件等因素进行了必要的研究。A new sulfonate method for synthesize β-naphthalene disulfonic acid by naphthalene and liquid SO3 was introduced. Experimental results indicated that the high-yield β-naphthalene disulfonic acid can be obtained, if blending of reaction materials and removing of the heat that produced in the reaction could be rapidly and well. In this paper, the reaction condition of sulfonation and isomerization etc. were introduced, and results indicated that high-yield β-naphthalene disulfonic acid （89%） can be obtained via this new method.
