Abstract

Highlights ► The reductive dechlorination of propachlor was efficiently achieved by dithionite. ► The transformation of propachlor initiated by dithionite follows second-order kinetics. ► Dechlorination was found to be the first and necessary step of propachlor transformation initiated by dithionite. ► Propachlor nucleophilic substitution by dithionite was confirmed as the S N2 mechanism.
