Dehydrochlorination Dichlorvos
Aug 10, 2018

Dichlorinated hydrogen of dichlorinated dichlorinated dichlorinated dichlorinated dichlorinated dichlorinated dichlorvos under alkaline conditions. Operation control between slurry water content is 25% (can also be refined trichlorfon mother liquor, and timely between solid), trichlorfon and alkali ratio is 1: (1.35 ~ 1.4), using water and toluene, xylene, benzene) two solvents, reaction temperature 50 ~ 60 ℃, the reaction time of 20 ~ 25 min, pH 7 ~ 8. The reaction caused the post-hydroxyphosphonate to rearrange into phosphates.



At the end of the reaction static stratification, the oil layer through the film evaporation recovery solvent, and dichlorvol crude oil.
