Toxaphene Use and Manufacturing

Methods of Manufacturing

From the reaction of camphene with chlorine. Turpentine oil is subjected to vacuum distillation to extract α-pinene, and isomerized in the presence of hydrated titanium oxide, and the isomerized liquid is subjected to vacuum distillation to obtain a dilute purity of more than 90%. Dissolve camphene in 2.5 times carbon tetrachloride and pass chlorine reaction. In the chlorination process, a batch method or a continuous method may be used. The carbon tetrachloride solution is reacted with chlorine gas in the tail gas of the chlorination reaction, and then the carbon tetrachloride solution is reacted with fresh chlorine gas. The chlorination reaction is carried out under light, and the reaction temperature is between 40-60°C. After the chlorine gas is reacted in series, the tail gas contains a small amount of residual chlorine and a large amount of hydrogen chloride. The tail gas pressure is about 10.7kPa, which can be used for absorption and comprehensive utilization by liquid alkali. After the chlorine content of the chlorinated liquid reaches 66.5-68.5%, after light, it is discharged to a steam distillation pot and distilled at 110°C to obtain toxaphene. The industrial product is a mixture of camphene isomerization reaction. Toxaphene powder with a chlorine content of 66.5-68.5% consumes about 700 kPa of turpentine per ton and 1350 kPa of chlorine gas. Commodities have 40% or 50% EC.

Uses

Insecticide.Not recommended for use in dairy barns or on milking animals (Penumarthy).
