Abstract

On prépare du méthyl-tert-butyléther (MTB) pur à partir de ses mélanges avec du méthanol. On élimine le méthanol de ces mélanges de manière azéotrope avec des hydrocarbures en C4 sous 1 à 25 bars et aux températures correspondantes. Le MTB obtenu directement pur 99,0 % à 99,9 % est utilisé comme solvant et comme anti-détonnant dans les carburants.
