摘　　要：介绍了一种通过加氢反应的化学精制法用于粗萘精制提纯的技术,通过加氢反应使工业萘转化成为四氢萘,并对反应副产物进行有效分离,最终得到高纯度的萘产品(萘的收率大于99%),为后续苯酐生产提供更高品质的原料,从而起到改善最终产品苯酐质量的目的。This paper introduces a chemical refining method for crude naphthalene by hydrogenation reaction.Through hydrogenation reaction,industrial naphthalene is transformed into tetrahydronaphthalene,and the reverse product is effectively separated.Finally,high purity naphthalene product is obtained(The yield of naphthalene was greater than 99%),which provides high quality raw materials for the subsequent production of phthalic anhydride,so as to improve the quality of the final product.

关 键 词：工业萘 加氢 精制 精馏
