Description

Technical Field

[0002] o-Fluorotoluene is an important fluorine-containing compound and has been widely used in the pharmaceutical and pesticide industries. The existing preparation method generally uses o-toluidine, hydrogen fluoride, and sodium nitrite as raw materials, and produces qualified o-fluorotoluene through steps such as salt formation, diazotization, thermal decomposition, water washing, and distillation; recovers hydrogen fluoride in the inorganic phase with concentrated sulfuric acid and produces waste sulfuric acid as a by-product; the tail gas is discharged into the air after washing with water, and dilute hydrofluoric acid is produced as a by-product. The by-product hydrogen fluoride gas produced during the reaction process is absorbed by falling film water and alkali. o-Fluorotoluene needs to be sampled and inspected during storage, and the deterioration of o-Fluorotoluene can be discovered in time.

[0003] When using the sampling device for o-fluorotoluene, the sampling depth is not convenient to adjust quickly, and the sampling depth cannot be measured during the sampling process. At the same time, the color changes of o-fluorotoluene at different depths cannot be intuitively displayed during sampling, so that o-fluorotoluene cannot be sampled and identified by color. In order to solve the above problems, a convenient sampling device for o-fluorotoluene is proposed in the present application. Utility Model Content
