LABOTEST-BB LT02085021 - Reference Information
| application | 2-chloro-6-fluorobenzyl can be used to prepare 2-chloro-6-fluorobenzaldehyde. 2-chloro-6-fluorobenzaldehyde is an important organic synthesis intermediate. In the pharmaceutical industry, 2-chloro-6-fluorobenzaldehyde is mainly used to produce fluocopenicillin with good antibacterial properties, which is a new generation of dichloropenicillin. The product has better curative effect; in the pesticide industry, 2-chloro-6-fluorobenzaldehyde is mainly used in the production of high-efficiency and low-toxic fungicides, and is called a biopesticide intermediate. |
| preparation | add 250 g2-chloro-6-fluorotoluene and 0.5ml phosphorus trichloride to a 500ml four-port glass reaction bottle equipped with a reflux condenser tube, an exhaust gas absorption device and a thermometer (adding phosphorus trichloride in this step can improve product quality), chlorine gas is introduced under the condition of keeping 180 ℃ under the irradiation of metal halide lamp to obtain 2-chloro-6-fluorochlorobenzyl. Use gas chromatography to detect the content of 2-chlorine-6-fluorochlorobenzyl in the liquid phase of the reaction bottle. When the content of 2-chlorine-6-fluorochlorobenzyl is detected to be less than 0.5%, stop the chlorine gas, and at the same time to the reaction bottle. Put nitrogen into the bottle to remove the unreacted chlorine in the bottle. |
| chemical properties | melting point 7 ℃, boiling point 208-210 ℃, flash point 93 ℃, density 1.401. A colorless liquid with certain tear irritation, which is corrosive to metallic iron. Insoluble in water, easily soluble in usual organic solvents. |
| use | mainly used as a synthetic raw material for pharmaceutical antibiotics and pesticide plant growth regulators this product is mainly used as a raw material for the synthesis of pharmaceutical antibiotics and pesticide plant growth agents, and is the basic raw material for the synthesis of many special chemicals. |
