Abstract: Butanol and dibutyl ether are separated from a mixture containing water, dibutyl ether and n-butanol, 2-butanol and/or isobutanol by a process in whicha) the mixture is introduced into a first distillation column, essentially butanol is separated off at the bottom of this distillation column and the mixture taken off at the top of the distillation columnb) is introduced into a second distillation column and essentially dibutyl ether is separated off at the bottom of this second distillation column and the mixture formed at the top of the second distillation column is removed,c) the second distillation column being operated at a higher pressure than the first distillation column and at least one of the two mixtures taken off via the top of the distillation columns being subjected to phase separation, only the organic phase separated off being fed to the second distillation column in the case of phase separation downstream of the first distillation column, and separation into an aqueous and an organic phase also being effected in the case of phase separation downstream of the second distillation column, a part stream being recycled from the top or rectification section of the second distillation column to the first distillation column.

Abstract: Method of devulcanizing rubber and/or elastomers without the need for a chemical agent, in which method the vulcanized rubber and/or elastomers are fed into a planetary roller extruder, which planetary roller extruder has a housing, a central spindle, two groups of planetary roller spindles, and a dispersion ring disposed about the central spindle and between the two groups of planetary spindles. Mechanical and thermal stress is generated on the vulcanized rubber and/or elastomers by kneading and/or crushing the vulcanized rubber and/or elastomers using the central spindle and the planetary spindles, and by forcing the vulcanized rubber and/or elastomers through the dispersion ring, which is designated to substantially restrict passage of the vulcanized rubber and/or elastomers therethrough. The mechanical and thermal stress alone is sufficient to break or destroy the molecular chains or bonds of the vulcanized rubber and/or elastomers.
