Description

Technical Field

[0001] The utility model relates to the technical field of lauroyl chloride distillation, in particular to a lauroyl chloride distillation system. Background Art

[0002] Lauroyl chloride is an important organic intermediate and is widely used in the synthesis of surfactants. In the production process of lauroyl chloride, a synthetic route using thionyl chloride as the chlorination agent is usually adopted. After the preparation is completed, the lauroyl chloride needs to be purified using a production purification device for the preparation of lauroyl chloride.

[0004] In the prior art, CN208234879U can make the liquid flow back and forth naturally between the bottom pot and the water storage device through the rotary distillation device when in use, thereby improving the utilization efficiency of water resources and the heat energy contained in the water resources, being low-carbon and environmentally friendly, and having a simple structure. However, when lauroyl chloride is distilled, the lauroyl chloride distillation container needs to be pressurized to a certain extent, so that the lauroyl chloride is vaporized, and then the distillation operation is realized, and it is difficult for the device in the prior art to realize the pressurization inside the container. At the same time, when lauroyl chloride is heated, the device in the prior art can only heat the bottom of the container, resulting in a relatively low heating efficiency, which in turn results in a slow distillation speed of the lauroyl chloride. Therefore, a lauroyl chloride distillation system is needed to solve the above problems. Utility Model Content
