Abstract

The present invention relates to a method for producing malathion, which comprises reacting O, O-dimethyldithiophosphoric acid (O, O-DMDTPA) with diethyl maleate in the presence of an acid, such as hydrochloric acid or sulfuric acid. Said method allows to isolate malathion containing impurities with less than 0.55% of O, O-DMDTPA by weight; With a malathion yield that reaches more than 90% in a period of less than 7 hours approximately.
