Diisopropylamine is mainly used for synthesizing pesticides in agriculture, the specific applications are as follows:
Synthetic herbicides: Diisopropylamine is an important intermediate for synthesizing certain sulfonylurea herbicides. For example, diisopropylamine can be used as raw material to synthesize herbicides such as bensulfuron and pyrazosulfuron. These herbicides hinder the synthesis of amino acids in weeds by inhibiting the activity of acetolactate synthase (ALS) in the body of the weeds, which in turn inhibits the growth of the weeds and eventually kills them. They are highly effective, low-toxic, environmentally friendly, etc. They can effectively prevent and eliminate broadleaf weeds and weeds of the Salix family in paddy fields, wheat fields and other agricultural fields, and are safe for crops with a long period of efficacy.
Synthetic insecticides: Diisopropylamine can participate in the synthesis of some organophosphorus insecticides. For example, in the process of synthesizing trichlorfon, dichlorvos and other insecticides, diisopropylamine can be used as raw material or auxiliary in the reaction. These organophosphorus insecticides inhibit the enzyme acetylcholinesterase in the body of the insect, causing the insect's nervous system dysfunction, and ultimately leading to the death of the insect. They have strong poisoning effects of touch, stomach and fumigation, and can effectively control a variety of agricultural pests, such as cabbage greenfly, aphids, fleas and so on.
Synthetic fungicides: Diisopropylamine can be used to synthesize certain nitrogen-containing heterocyclic fungicides. For example, diisopropylamine is one of the important intermediates in the synthesis of fungicides such as etofenprox. Etofenprox is mainly used for the prevention and control of gray mold, botrytis and other diseases on vegetables, fruits and other crops, which can inhibit the mycelial growth and spore germination of pathogens, and has a good protective and therapeutic effect.
