摘要： The invention relates to a method for producing methyl tert-butyl ether (MTBE) in qualities which are suitable for organic syntheses and for using as special solvents, from MTBE in fuel quality. The inventive method is characterised in that technical MTBE is separated into a fraction having a low boiling point and containing MTBE, methanol and water, a fraction having an average boiling point and containing MTBE at a level of purity higher than 99.7 %, and a fraction having a high boiling point and containing TBA and butene oligomers.
