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