Synthesis method
1. Dissolve o-isopropylphenol in dehydrated dioxane, add methyl isocyanate and triethylamine dropwise, and gradually heat up the reaction mixture. Cool and precipitate crystals. After adding petroleum ether, the crystals will completely precipitate. Collect the crystallization product, which is propoxur. The by-product urea is washed with petroleum and water, remove the solvent, dry under reduced pressure at 50°C, and recrystallize from benzene to recover it. Kill the power. Raw material consumption quota: o-isopropylphenol 890kg/t, methyl isocyanate 330kg/t, dehydrated dioxane 150kg/t, petroleum ether 500kg/t.
2.Chloroformate method
Synthesize isopropoxy first Phenolic chloroformate is then aminated to synthesize propoxur. Both reactions are carried out at low temperatures.
Purpose
1. Non-systemic pesticides. It has contact killing, gastric poisoning and fumigation effects. It knocks down quickly, has a rapidity close to dichlorvos, and has a long lasting effect. It can kill external parasites, household hygiene pests (mosquitoes, flies, cockroaches, etc.) and storage pests.
2.A fast-acting, long-residual carbamate insecticide with contact killing, gastric poisoning and fumigation effects, but no systemic effect. Mainly used to control rice borers, rice leafhoppers, rice planthoppers, cotton aphids, fruit tree scale insects, rust ticks, cereal pests and sanitary pests.
