Chlorine-DDT Use and Manufacturing

Methods of Manufacturing

DDT chloride is synthesized from DDT as a raw material. Put DDT into the 1500L enamel tank one after another, and pass steam into the jacket to maintain the vapor pressure at 0.15～0.2MPa. After the DDT is melted, press air into the chlorination tank, add catalyst and stabilizer to maintain the vapor pressure of the chlorination tank jacket Not less than 0.6 MPa, when the temperature rises to 155 ℃, start to vent chlorine gas, the chlorine gas temperature is controlled between 160 ~ 165 ℃, the chlorine gas flow rate is 15 ~ 20kg/h, the generated HCl gas is pumped into the hydrochloric acid absorption tank, and water For absorption, the exhaust gas is passed into the lye absorption tank and then emptied. The industrial product of chlorinated DDT is a light yellow viscous solid with a content of 70% to 72%. It is insoluble in water, slightly soluble in absolute ethanol, and easily soluble in aromatic hydrocarbon solvents and acetone.

Uses

Chlorinated DDT is an important intermediate in the synthesis of acaricide triclosan.
