Analyze the exchange method of molecular stills

    The exchange method of molecular stills is mainly used for the separation and purification of temperature-sensitive and unstable compounds. The control system in the equipment is mainly used to reduce the boiling point of the material. The structure of the molecular still can control the continuous material. It is heated in the form of a thin film as indicated by the equipment.
    During the operation of the molecular still, the condensing surface and the thin surface of the device directly form a pressure difference. The resulting pressure difference is the driving force for the entire steam flow direction. A small pressure drop in the equipment will result in the flow of steam, and the distance between the condensing surface and the boiling surface during the molecular distillation operation is relatively short.
     During the use of molecular stills, the material stays in the equipment for a short period of time. The device is also suitable for its high viscosity material. In the selection process, good materials can be used, using a small coefficient of thermal expansion and a chemically stable quartz glass material.
     During operation, the molecular distiller has high strength and the device has strong corrosion resistance during use. The product has good performance on most reagents and chemical materials.
     In the design process, the manufacturing process is developed according to the design concept. The main component of a molecular still is a distillation column. In the process of use, the structure of the equipment is directly related to the separation of the equipment.
     In the selection process, the molecular distiller needs to select an economically reasonable distillation temperature so that the material has a good stability during the processing. Vapor molecules may collide with each other in the evaporation process that faces the condensing surface.
     The operating environment of the molecular still and the heat exchange between the towers can avoid the traditional methods, which will directly lead to the error of the experimental data, which is caused by the overheating of the equipment or the insulation. Destroy its balance. During mass transfer, molecular distiller can regulate and control vacuum temperature and pressure conditions. The column in the equipment is designed with a thermal expansion pleat section to avoid the sudden change in temperature of the column.
