Open Data Verified Data
dimethylamine and liquid alkali were added dropwise to allyl chloride, and the reaction was heated to obtain N,N-dimethyl propylamine, which was acidified with hydrogen chloride and chlorinated with chlorine gas, 1-= methylamino -2,3-= chloropropane was obtained. By adding the chloride and liquid alkali prepared as described above to sodium thiosulfate, an aqueous insecticidal double solution can be obtained.

Open Data Verified Data
silkworm poison pesticide, is a biological insecticide. It is effective for lepidopteran pests, with strong killing, stomach poison, internal absorption and egg killing effect. By blocking the nerve conduction of the pest, the worm gradually softens and paralyzes to death. Insecticidal double on rice, wheat, corn, beans, vegetables, citrus, fruit trees, tea, forest and other crops of the main pests have excellent control effect, mainly used for the control of rice borer, rice longitudinally rolled leaf cicada, Rice thrips, negative mud insects, etc., can also be used to control citrus leaf moth, corn borer, aphids, cotton red spider, cabbage, etc., sericulture area is best to use granules, anhydrous paddy field particles should not be used.

Thiosulfuricacid,S,oxalate-[2-(dimethylamino)-1,3-propanediyl]esterdisodiumsalt - Reference Information
| application | 1-thiosulfonic acid sodium -2-dimethylamino-3-thiosulfonic propane (belonging to sand incense toxin pesticides, is a broad-spectrum, high-efficiency, low-toxicity, low-residue biomimetic pesticide. |
| use | nereis toxin pesticide, which is a biomimetic pesticide. It is effective for lepidopteran pests and has strong contact killing, stomach poisoning, absorption and egg killing. By blocking the nerve conduction of pests, the worms gradually soften and paralyze to death. Mainly used to control rice stem borer, stem borer, rice rolling leafhopper, rice thrips, rice bracts, negative mud, etc., with 7.5~11.3g active ingredient/100m2 water spray. It can also be used to control citrus leaf miner, various aphids, red spiders, corn borer, cabbage, etc. Granules are best used in sericulture areas, and granules are not suitable for anhydrous paddy fields. It is used to control pests of vegetables, rice, wheat, fruit trees and other crops It is used to control rice pests and has good control effects on rice Chilo suppressalis, Chilo suppressalis, rice leaf roller, rice thrips, etc. It has the effects of stomach toxicity, contact killing and internal absorption conduction, and also has a certain fumigation effect. It is used to control rice leafhopper, planthopper, rice bracts, vegetable yellow striped jumper, cabbage worm, pear tree binary aphid, etc. The recommended dosage is 7.5~11.3g active ingredient/100 m2. The active period is 1 week. The control effect on rice stem borer and stem borer was 80% ~ 97%, and that on rice stem borer was 70% ~ 95%. This product was successfully developed on the basis of carborol. The insecticidal double can be made into an insecticidal single by acidification. Insecticidal single (or insecticidal double) is cyclized with sodium sulfide and salted with oxalic acid to obtain insecticidal rings. Dioscordon, insecticidal single, insecticidal ring, and insecticidal double all have stomach poison, contact and bone suction effects. Double insecticide has excellent control effects on the main pests of rice, three wheat, corn, beans, vegetables, oranges, fruit trees, tea, forests and other crops, such as rice borer, Chilo suppressalis, Chilo suppressalis, Chilo suppressalis, rice leaf roller, rice bracts, leafhopper, rice thrips, negative mud, Chinese rice borer, cabbage borer, cabbage worm, yellow striped beetle, peach aphid, pear caterpillar, citrus leaf miner, etc. |
| production method | dimethylamine and liquid alkali are added dropwise to propylene chloride at 0 ℃, after dropping, heated to 45 ℃ for 2 hours to prepare N,N-dimethylacrylamide, acidified with hydrogen chloride to pH = 2, controlled to temperature 0-10 ℃, chlorinated with chlorine gas, and adjusted to pH = 3-4 with alkali, 1-dimethylamino-2, 3-dichloropropane was prepared. Add sodium thiosulfate at 40 ℃, raise the temperature to 60 ℃, add the chloride and the 3/5 amount of liquid alkali, react at 70 ℃ for 3h, then add the remaining amount of liquid alkali, stir at 63-65 ℃ for half an hour, to obtain a 30% aqueous solution of insecticidal double. Raw material consumption quota: 380kg/t chloropropene, 650kg/t dimethylamine (40%), 1680kg/t sodium thiosulfate, 110kg/t hydrochloric acid (31%), 330kg/t liquid chlorine (99.5 ℃), 850kg/t liquid alkali (40%). Hydrocidal double is acidified with appropriate amount of hydrochloric acid to generate insecticidal single. Chloropropene and dimethylamine are aminated in the presence of sodium hydroxide to prepare N,N-dimethylacrylamide. Then neutralize with 30% hydrochloric acid to form hydrochloride. The hydrochloride is chlorinated in chloroform solvent to obtain 1-N, N-dimethyl-2, 3-dichloropropylamine hydrochloride. Finally, it reacts with sodium thiosulfate to synthesize insecticidal double. The reaction product is actually a mixture of double active body, double isomer and their monosodium salt. Due to partial neutralization to pH 6~7, there are actually single sodium salt active body and single sodium salt inactive body. The above are the main domestic production methods. Shenyang Chemical Research Institute and other units use solvent process, so that the quality and yield of insecticidal double is improved, the consumption quota is reduced. |
