摘要：the present invention relates to a method for cleavage of methyl - ments.-butyl (mtbe), that at least the steps destillative separation of mtbe broken flow in amtbe broken kopfstrom ii and a sumpfstrom iii, which is higher than mtbe boilingconnected, and cleavage of the kopfstrom ii contained in a catalyst mtbe under it hold aspaltproduktes iv contains, which is distinguished by thethe current i of a proportion of 2methoxybutan (msbe) of greater than 1000 mass ppm in terms of mtbe has, and that thedestillative separation in step (a) and \\/ or the division step (b) is implemented in such away that the obtained fission product iv, a concentration of less than 1000 mass n - linearbutenen ppm relative to the c4 olefinfraktion contains.
