Molecular formula: C10H10CL8
molecular weight: 413.8
CAS:
density: the relative density of 1.65 (25 ° C)
melting point: 70 to 95 ° C within the scope of softening. ° C
traits: yellow waxy solid, with a slight odor of turpentine.
dissolution: room temperature, the water solubility of about 3 mg / L, soluble in organic solvents (including oil).
purposes: an organic pesticides. Toxaphene non-absorption of the toxic pesticides smoothly and stomach, and have some Acaricidal activity. Hyacinth plants, in addition to other crops no phytotoxicity. Major cotton boll stage for the fight against pests, such as cotton boll worms daughters, Platyedra gosspiella Saunders, cotton aphids. Also for maize, rice, vegetables, ramie, fruit trees, forests, control pests, such as rice stem borer, rice shell insects, rice thrips, planthopper, leafhoppers. 50% of the EC objects and usage: bollworm to 400 ~ 800 fold spray; Soil pests, dipping to 100 fold species; Forest pest, ~ 500 to 200 fold spray; Corn soil pests, 100 times the soaking. Preparation or
Source: Camphene by reaction with chlorine in the system. Turpentine by vacuum distillation from alpha-pinene, in the presence of a hydrated titania isomerization, isomerization of the vacuum distillation purity was above 90% of camphene. Camphene be 2.5 times the soluble carbon tetrachloride, chlorine-reaction. Green space law or the process can be continuous, the first solution and carbon tetrachloride Camphene chlorination reaction of chlorine in the exhaust gas, then this Camphene with fresh carbon tetrachloride solution of chlorine reaction. In response green light irradiation, exhaust containing small quantities of chlorine and hydrogen chloride large, exhaust pressure 10.6kPa about Utilization absorption liquid caustic soda available. The chloride content of 66.5% to reach 68.5%, expected to release steam distillation reactor, in a 110 ° C distillation toxaphene. The original drug for Camphene chloride isomerization reaction mixture, the chlorine content of 66.5% to 68.5%. Preparations for the 50% of the EC.
Note: heating, strong sunlight and certain catalyst (such as iron) exist, toxaphene off hydrogen. Not with strong alkaline mixtures of pesticides. Anhydrous conditions, no corrosion. The acute oral LD50 in rats of 80 mg to rat acute percutaneous LD50 780 ~ 1075mg/kg, two in rats fed non-mg dose of feed role in the accumulation of body fat in its accumulation of feeding rats in proportion to the dose, but stopped only administration, in vivo accumulation can be quickly ruled out. Workplace toxaphene the maximum allowable concentration of 0.5 mg / cubic meter.
packaging and transportation: EC by the GB3796, GB4638 packaging. Store in cool dry ventilation, and no food, and feed-mixing.
