磺化反应在现代化工领域中占有重要地位 ,是合成多种有机产品的重要步骤 ,在医药、农药、染料、塑料、涂料、洗涤剂及石油等行业中应用较广。本文介绍了以三氧化硫为主的磺化剂磺化甲苯、长直链烷基苯、硝基苯、萘及其衍生物、蒽醌、直链烷烃和烯烃的工艺 ,对影响反应的因素进行了讨论 ,并介绍了较典型的磺化反应装置。 Sulfonation plays an important role in modern chemical industry. It is an important step in the synthesis of many organic products. It is widely used in medicine, pesticide, dye, plastic, paint, detergent and oil industries. This article describes the sulfur trioxide-based sulfonated toluene sulfonated toluene, long straight-chain alkyl benzene, nitrobenzene, naphthalene and its derivatives, anthraquinone, linear paraffins and olefins process, the impact of the reaction of the factors Discussed, and introduced the more typical sulfonation reactor.
