摘要： In a process for recovering pure methylal from methanol-methylal mixtures, which can optionally contain still further compounds, the separation conducted in a rectification device comprising two rectifying columns. In the first rectifying column, the mixture to be separated is rectified under a pressure lower than that in the second column, into a methylal-rich, methanol-poor distillate, and into a practically methylal-free, methanol-rich sump product. The methylal-rich distillate of the first rectification is then separated in a second rectifying column, operated under a higher pressure than the first rectification column, into a compound stream containing methanol and methylal, which is then recycled to the first rectifying column, and into pure methylal as the sump product. In a specific refinement, the first rectification is preferably operated under a pressure of 1-22 bar absolute and the second rectification preferably under a pressure of 9-30 bar absolute, with the second rectification being operated under a pressure which is at least 8 bar higher than that of the first rectification.

摘要： A process for the simultaneous manufacture of pure methyl tertiary butyl ether (MTBE) and a substantially isotubene-free mixture of C.sub.4 -hydrocarbons, by reacting the isobutene contained in the mixture of C.sub.4 -hydrocarbons with excess methanol in the liquid phase at elevated temperatures on strongly acid, macroporous, organic ion exchange resins.The process has the following steps:(a) methanol and isobutene are reacted in a molar ratio of 2:1 to 5:1 at temperatures between 30.degree. and 100.degree. C.;(b) the unconverted hydrocarbons are then removed as the top product under a pressure of 2 to 10 bars from a first rectification column;(c) the bottom product from this first column is rectified in a second column under normal pressure or under a slight excess pressure of up to 2 bars at the top of the column, the bottom product of this rectification is recycled to reaction zone (a), if necessary, after separating off a portion of the tertiary butanol formed and the C.sub.8 -olefins; and(d) the distillate from this second column is rectified in a third rectification column under a pressure of 5 to 30 bars, the distillate thus obtained is recycled into the feed to the second column and pure methyl tertiary butyl ether is withdrawn from the bottom of the third column.
