Abstract

Vynález rieSi čistenie 0,0-dimetyl-0- -(3-metyl-4-nÍtrofenyl) tiorosfátu extrakciou s vodným roztokom NaOH a/alebo NagCO^ pričom na ich přípravu sa použije voda získaná po oddestilovaní aromatického uhlovodíka od 0,0-dimetyl-0-(3-metyl-4-nitrofenyl)tiofosfátu, ktorá neobsahuje vápenaté a horečnaté soli, ktoré by sa vyzréžali s NagCOj a/alebo NaOH. Vynález nájde uplatnenie pri výrobě Q,0-dimetyl-0-(3-metyl-4-nitrofenyl)tiofosfátu, ktorý sa používá ako insekticid.
