overview
Bensultap, chemical name S,S'-[2-(dimethylamino) dimethyl] dithiobenzenesulfonate, white scaly crystal, melting point 83~84 ℃, about 150 ℃ decomposition. Soluble in chloroform, dichloroethane, ethanol, acetone and acetonitrile, slightly soluble in toluene, benzene, ether, insoluble in water. This product is a Nereis toxin pesticide product developed by Japan's Takeda Company in the 1970s. Sand silkworm toxin insecticides occupy an important position in pesticide products. They are mainly used for the control of crop pests such as rice, cotton, fruit trees, tea and hemp, and for crops such as wheat, three wheat, beans and vegetables, as well as citrus and forest The main pests have control effects. They are promising pesticides that replace the organochlorine pesticides BHC and DDT after they are discontinued.
application
Ethnocidal is a kind of Nereis toxin pesticide. It is insoluble in water and soluble in organic solvents such as methanol and acetonitrile. It is a commonly used insecticide with high efficiency, low toxicity and low residue. It can be used to control a variety of leaf-eating pests and borer pests on various crops such as rice, vegetables, sugarcane, fruit trees, etc, it also has a good control effect on aphids, leafhoppers, planthoppers, thrips and mites. Insecticide has strong contact and stomach toxicity to pests, and also has certain absorption and fumigation effects. It has lethality to adults, larvae and eggs.
chemical properties
white crystalline solid. The melting point is 83-84 ℃, and it decomposes at about 150 ℃. Its hydrochloride melting point is 163 ℃, oxalate melting point is 127-128 ℃ (decomposition). It is stable in acidic solution, and its free base is stored at room temperature for several months without change.
use
the product has stomach poison and contact killing effect, causing pests to paralyze, poison and refuse to eat and die. It can control a variety of pests on potatoes, corn, and rice, and has a strong killing effect on rice stem borers, potato beetles, diamondback moth and other lepidoptera and Coleoptera pests.
Production method 2-N, N-dimethylamino-1, 3-dichloropropane and sodium thiobenzenesulfonate are refluxed in ethanol.
