Procedure

Onto the p,p'-DDE obtained in Stage (b) 100 ml water is added, the mixture heated to 80° C.-85° C. and chlorine gas added over a period of 8-11 hours, until the concentration of p,p'-DDE drops to 0.2%. The upper aqueous phase is separated to afford 410 g p,p'-DDT, which was used directly in the next stage.

Workup

  1. temperaturethe mixture heated to 80° C.-85° C.
  2. customThe upper aqueous phase is separated
