Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to a purification device for ethylsilane. Background Art

[0002] Ethylsilane is a chemical substance, which is a colorless and transparent silicone intermediate. It is easily hydrolyzed to release ethanol and generate corresponding condensation products. Ethylsilane is generally purified by distillation. In the Chinese utility model patent application number: CN202021436491.1, there is disclosed a purification device for ethylsilane, which is discharged to a distillation box through a feed pipe for further distillation and purification, so that the ethylsilane component in the solution after distillation can continue to be purified by secondary distillation, thereby making the purification work more efficient and avoiding waste, and avoiding the difficulty of distillation and purification due to the high concentration of the solution when the solution is distilled again.

[0003] Although the above patent realizes the purification function of ethylsilane, the above patent has the following disadvantages when used: the existing ethylsilane purification device usually uses condensate to condense ethylsilane, but does not set a cooling mechanism for the condensate, which results in that after the condensate condenses a group of ethylsilane, the temperature of the condensate will rise due to the heat conduction effect. When it is recycled for secondary use, the condensation effect of the next group of ethylsilane will deteriorate, which is inconvenient to use. Therefore, we propose a purification device for ethylsilane. Utility Model Content
