Abstract
Description
technical field
[0001] The invention relates to 2-acetoxy-N-(3-nitrophenyl)benzamide, a preparation method and application thereof, and belongs to the field of pesticides. Background technique
[0002] Pesticide refers to a class of drugs that are used to kill insects, sterilize bacteria, and kill harmful animals and plants in order to ensure and promote the growth of plants and crops in agricultural production. Specifically refers to pesticides used in agriculture to control diseases and insect pests, regulate plant growth, and kill weeds. Pesticides are closely related to agriculture and animal husbandry, and are closely related to life. Therefore people have known for a long time that pesticides are used to prevent and control the pests and diseases of crops. More than 1000 BC, in ancient Greece, it has been used sulfur fumigation Records of pest and disease prevention, my country also began to use it in the 5th to 7th centuries BC Mangcao , Mirage ash, Muju, etc. to...

[0029] Example 1 Preparation of 2-acetoxy-N-(3-nitrophenyl)benzamide
[0030] Dissolve 3-nitroaniline (30mmol) and o-acetoxybenzoyl chloride (30mmol) in 10mL of dichloromethane respectively, put the dissolved 3-nitroaniline into a three-necked flask, and then Add pyridine (30mmol), put it into a 30°C constant temperature water bath, then slowly drop the dissolved o-acetoxybenzoyl chloride into the three-necked bottle, use a magnetic stirring device to stir continuously for 3-4 hours, take it out with 2 Elute with 10% hydrochloric acid that is twice the volume of the reaction solution for 2-3 times, place in a refrigerator at 2-6°C until a solid precipitates, filter, wash, and recrystallize with absolute ethanol until the pure substance is obtained.
[0031] The structural identification of the prepared 2-acetoxy-N-(3-nitrophenyl)benzamide substance is as follows:
[0032] through IR, 1 The structure was confirmed by H NMR, and the results of the analysis were as follows:
