Raw material feeding and reaction (blue area): n-butanol, hydrobromic acid, and the catalyst are fed into the bromination reactor, which is equipped with stirring mechanisms as well as heating/cooling jackets, either through pumps or directly via pipelines. The reaction is carried out at specific temperatures (100–120°C) and pressures to produce a mixture containing the target product. 2. Preliminary separation (orange area): The product mixture after the reaction enters the phase separator. Taking advantage of the difference in liquid densities, the mixture separates into layers when left to stand. The layer of waste acid water at the bottom is separated and removed, while the upper layer of crude organic phase proceeds to the subsequent purification unit. 3. Washing and neutralization (green area): The crude organic phase first enters the washing tower, where water is used to remove water-soluble impurities. Next, it enters the neutralization tower, where an alkaline solution is added to react with the remaining acid. The wastewater and spent alkali solution generated in this step are sent for treatment. 4. Drying and dehydration (left side of the yellow area): The wet material, after washing and neutralization, enters the drying tower to have the moisture contained in it removed. 5. Distillation purification (right side of the yellow area): The dried crude product is fed into a distillation tower for final purification and separation. Top of tower: After the light components and solvent evaporate, they are condensed in a condenser; part of this condensed liquid is recycled, while another part is recovered as light components. Bottom of tower: The heavy components are discharged as waste liquid. Sideline extraction: The qualified refined bromobutane is extracted from the side of the distillation tower and then sent to the bromobutane product tank for storage. The entire process is a typical chemical synthesis and post-treatment procedure, comprising five main stages: reaction synthesis, physical separation by layering, chemical washing and neutralization, drying and dehydration, and distillation for purification, ultimately yielding high-purity bromobutane product.
