摘要/Abstract

摘要：

工业萘含有杂质苯并噻吩、酚类、喹啉类及不饱和化合物，影响萘的进一步利用。主要杂质苯并噻吩与萘的沸点相近，无法直接精馏分离。以过氧化氢为氧化剂，甲酸为催化剂，用氧化法可以有效除去工业萘中的苯并噻吩。

Abstract:

Industrial naphthalene contains impurities of benzothienyl,phenols,quinolines and other unsaturated compound which has bad influences on the further application of naphthalene.The boiling points of naphthalene and main impurity benzothiophene are too close to separate each other directly by distillation.Using hydrogen peroxide as oxidant,formic acid as catalyst,oxidation method can be effectively used for the removing of benzothiophene from industrial naphthalene.Industrial naphthalene; Benzothiophene; Refined naphthalene; Hydrocarbonylation
