42721-99-3 - Preparation Method
Open Data Verified Data
phenylacetone is formed by the acylation reaction of phenylacetic acid and acetic anhydride, and phenylacetone is brominated and phenylated to produce meta-diphenylacetone. Then, the solvent toluene and the catalyst sodium methoxide were put into the reactor, and after azeotroping, a mixed liquid of dimethyl phthalate and toluene was added, and a mixed liquid of toluene of meta-diphenylacetone was added dropwise. In an acidic or neutral medium, the product obtained is an enemy rat, and the enemy rat sodium salt is obtained in an alkaline medium.

Open Data Verified Data
is an anticoagulant rodenticide. The target spectrum is broad, the palatability is good, the function is slow, the effect is obvious. When administered up to a lethal dose, the destruction of the rat blood thrombin hyperactivity, so that the duration of prolonged, a large number of rats with internal bleeding and hypoxia, until death. For housing, grain depots, ship wharf and other places to kill rats. It can also be used for rodent control in dry field, paddy field, forest area and grassland. Poison baits are mostly prepared with rice or flour, and can also be used with sweet potato, carrots, silk and other baits.
