[0002] 2,6-Diethylaniline is one of the most important amine substances. It is an important organic synthesis intermediate used in the manufacture of dyes, medicines, spices and pesticides. It can replace tetraethyl lead as a gasoline antiknock agent. It is also an important pesticide, dye and pharmaceutical intermediate, and a raw material for amide herbicides alachlor and butachlor. The herbicide alachlor produced with 2,6-diethylaniline as raw material is mainly used for weed control in crops such as corn, soybeans and peanuts; it is also used to produce the herbicide butachlor, which is mainly used for weed control in rice fields.

In the utility model, the spirally distributed stirring blade can twist the material at the bottom end of the reactor body through the inner cylinder to the top of the reactor body during rotation, and the material is quickly circulated up and down.

Therefore, a reactor with good mixing effect is proposed to solve the above problems. Utility Model Content
