Description
Technical field: [0001] The invention relates to a device for continuously producing and purifying brine produced by polysulfide silane coupling agents, and belongs to the technical field of chemical production equipment. Background technique: [0002] In the water phase production process of polysulfide silane coupling agent, sodium chloride is formed as a by-product. When the organic phase polysulfide silane coupling agent is separated from the water phase, sodium chloride is separated in the form of aqueous phase of brine . Since the organic chemical reaction cannot be 100% complete and the two phases cannot be 100% separated, there will be a small amount of polysulfide silane coupling agent suspended in the water phase in the form of droplets. If the polysulfide silane coupling agent is not removed from the water phase, it will inevitably have an adverse effect on the next step of the water phase's environmental protection treatment. At present, there is a process for ...
