| Overview | Halogenated benzamide compounds include 2, 6-dichlorobenzamide is a key intermediate for the synthesis of benzoylurea insecticides. Benzoylurea insecticides are chitin synthesis inhibitors, which kill insects by inhibiting the biosynthesis of chitin in insects. Its mechanism of action is different from other pesticides, it has the characteristics of high insecticidal activity, wide insecticidal spectrum, low residue, strong selectivity, and safety to humans and animals. It is an environmentally friendly insecticide variety. Benzoylurea insecticides are the main varieties of insect growth regulator pesticides, and the demand at home and abroad is relatively large. Therefore, the development of key intermediates has attracted much attention in the pesticide industry. |
| preparation | preparation including 2,6-dichlorobenzamide is as follows: in a 500ml reaction bottle, 51.6g(0.3mol) of 2,6-dichlorobenzonitrile, 41.6g of water, 0.6g of 30% sodium hydroxide solution, heating to 35 ℃, dropping 55.65g(0.45mol) of 27.5% hydrogen peroxide, after 5 hours of dropping, the sampling is controlled, and 2,6-dichlorobenzonitrile ≤ 0.5% is qualified. Filter, rinse the filter cake with 83.2g of water, and dry the wet product to obtain the finished product 2,6-dichlorobenzamide 55g, with purity> 99.0% and yield 97%. |
