Abstract

A találmány tárgya eljárás 4-metoximetil-2,3,5,6-tetrafluorbenzilalkohol előállítására 4-hidroximetil-2,3,5,6-tetrafluorbenzilalkohol szelektív monometilezése útján. A találmányabban áll, hogy kiindulási anyagként 4-hidroximetil-2,3,5,6-tetrafluorbenzilalkoholt egy szervetlen bázissal reagáltatnak vízben,majd ezután dimetilszulfátot, valamint szénhidrogének és éterek közülmegválasztott, vízzel nem elegyedő szerves oldószert adnak areakcióelegyhez.
