氯乙烯合成方法主要有乙烯氧氯化法和乙炔氢氯化法,其中70%的氯乙烯由乙炔氢氯化法合成,但乙炔氢氯化法采用的催化剂是剧毒的氯化汞,因此在反应过程难免会危害到生物及自然环境的安全。鉴于此,本文就乙炔法合成氯乙烯用氯化汞催化剂的改良展开讨论,以响应低碳环保及可持续发展理念的号召。 The main synthetic methods of vinyl chloride ethylene oxychlorination and acetylene hydrochlorination, of which 70% of the vinyl chloride from acetylene hydrochlorination synthesis, but acetylene hydrochlorination catalyst is highly toxic mercuric chloride, therefore In the reaction process will inevitably endanger the safety of biological and natural environment. In view of this, this article discusses the improvement of acetylene chloride synthesis of mercuric chloride catalyst to respond to the call of low-carbon environmental protection and sustainable development.
