Production method
Preparation method: Aniline and ethylene were prepared by alkylation reaction under the action of catalyst. There are two kinds of production processes: continuous and intermittent. The main catalysts are triethylaluminum, diethyl aluminum chloride, aluminum trichloride plus aluminum powder and aluminum chips. Raw material consumption quota: aniline (≥99.6%)695kg/t, ethylene (≥99.9%)470kg/t, aluminum powder (≥99.7%)14.5kg/t, aluminum trichloride (≥99%)44kg/t, sodium hydroxide solution (42%)91kg/t, sulfuric acid (93%)60kg/t.
Use
2, 6-diethylaniline is an important pesticide, dye and pharmaceutical intermediate. The pesticide field is a key intermediate in the production of the herbicide butachlor and can also be used in other organic synthesis.
