氯化溴的微反应连续合成与应用
Microreaction continuous synthesis and application of bromine chloride
摘要
Abstract
Bromine chloride is an important halogenating reagent in industry.Its synthesis has many challenges such as high heat release,low production efficiency and serious potential safety hazards.The continuity and miniaturization of producing equipment is an important development direction of bromine chloride synthesis technology.To develop microreaction technology for preparing bromine chloride via absorbing chlorine by means of dichloromethane solution of bromine,the mass transfer performances of Corning G1 reactor,Jinde C1 reactor and self-made micromixer + micro packed reactor were investigated.Continuous and stable preparation of bromine chloride was realized and the space-time yield of the microreactors reached 2.25g/(min∙mL).Bromination of polystyrene was implemented using the bromine chloride prepared from microreactors,and brominated polystyrene products with mass percentage>66% bromine content and 5% thermogravimetric temperature>370℃ were obtained.关键词
