Method for reducing thermal hazards in uv resin prepolymer synthesis reactions and applications

Abstract

The application belongs to the field of chemical thermal safety, and discloses a method for reducing thermal hazards in the synthesis reaction of UV resin prepolymer and application. The reaction heat or temperature of the reaction system is monitored online and in real time, and according to the temperature or reaction heat signal obtained by detection, the reactants are added into the reaction system in multiple times or dropwise, the temperature rise of the system is controlled, and the thermal hazards in the synthesis reaction of UV resin prepolymer are reduced. By combining the reactant feeding mode with the reaction calorimetric analysis, once feeding leads to severe exothermic and temperature rise; multiple feeding can reduce the exothermic intensity of each time; continuous dropwise feeding can control the temperature of the reaction system. The multiple feeding and dropwise feeding mode can reduce the heat accumulation, from the perspective of thermal safety, the method significantly improves the process safety in the synthesis process of UV resin prepolymer, provides key data support for the process, is suitable for safety amplification in industrial production, has significant application value, and the method is expected to be widely applicable to similar reactions.
