PROCESS FOR PRODUCTION OF PURIFIED O-(2,6-DICHLORO-4-METHYL- PHENYL) O,O-DIMETHYL PHOSPHOROTHIOATE

摘要

A process for producing a purified O-(2,6-dichloro-4-methylphenyl)-O,O-dimethyl phosphorothioate, the process comprising:
the first step of bringing a crude O-(2,6-dichloro-4-methylphenyl)-O,O-dimethyl phosphorothioate into contact with an acid; and
the second step of recovering the purified O-(2,6-dichloro-4-methylphenyl)-O,O-dimethyl phosphorothioate from the mixture obtained in the first step.
