    Abstract: A process for separating a mixture comprising a) a monoolefinically unsaturated compound which is obtainable by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, or a saturated compound obtained by hydrogenating such a compound, b) a compound which is obtainable by adding more than two of the terminal olefins mentioned in a) or a compound obtained by hydrogenating such a compound, and c) a compound which contains a transition metal, is homogeneous with respect to the mixture and is suitable as a catalyst for preparing a monoolefinically unsaturated compound by adding two terminal olefins which bear the functional groups required to prepare the monoolefinically unsaturated compound containing at least two functional groups, by means of a semipermeable membrane to obtain a permeate and a retentate in such a way that the weight ratio of component b) to component c) in the mixture fed to the semipermeable membrane is smaller than in the retentate.

    Abstract: A method for the production of propylene oxide (PO) by reacting propene with a hydroperoxide in a nitrile-containing solvent in presence of a porous oxide-containing catalyst, involves using a zeolite catalyst with an X-ray crystal structure of the MWW type. An independent claim is also included for formed catalyst bodies containing the above type of zeolite.

    Abstract: A process for dewatering hydrocyanic acid by distillation, which includes distilling crude hydrocyanic acid containing from 50 to 99.9% by weight of HCN, from 0.1 to 40% by weight of water, from 0 to 15% by weight of carbon oxides and optionally from 0.01 to 1% by weight of an involatile stabilizer, at a pressure of from 1 bar to 2.5 bar, a bottom temperature of from 100° C. to 130° C. and a top temperature of from 25° C. to 54° C., in the absence of a volatile stabilizer, in a distillation column to obtain a top draw stream containing purified, anhydrous hydrocyanic acid and carbon oxides and a bottom draw stream including water and, optionally, the involatile stabilizer.

    Abstract: A process for the purification of crude caprolactam, prepared by reaction of a mixture comprising 6-aminocapronitrile and water, comprises a three stage distillation process with feeding of the crude caprolactam and an inorganic acid having a b. pt. above the b. pt. of the caprolactam to a first distillation column. A process for the purification of crude caprolactam, prepared by reaction of a mixture comprising 6-aminocapronitrile and water in the presence of a catalyst to form a mixture comprising caprolactam, ammonia, water and high and low b. pt. byproducts followed by removal of ammonia to yield a mixture of caprolactam, water and high and low b. pt. byproducts followed by at least partial removal of water to yield a crude caprolactam containing caprolactam and high and low b. pt. byproducts, comprises: (a) feeding of the crude caprolactam and an inorganic acid having a b. pt. above the b. pt. of the caprolactam to a first distillation column; (b) distillation of the crude caprolactam and inorganic acid to form a sump stream and an overhead stream; (c) feeding of the overhead stream to a second distillation column; (d) distillation of the stream to form a sump stream and overhead stream; (e) feeding of the overhead stream to a third distillation column; (f) distillation of the overhead stream to form a sump stream and purified caprolactam in the overhead stream; and (g) feeding of the sump stream to the first distillation column.

    Abstract: Continuous process for the epoxidation of olefins by means of hydroperoxide, in which the epoxidation is carried out in a reactor in which at least one catalyst suspended in a liquid phase is present, wherein the liquid phase is passed through a device which has openings or channels and is installed in the reactor and the epoxide-containing liquid is separated off by means of crossflow filtration so that the suspended catalyst is retained in the reaction system.

    Abstract: The invention relates to a method for the production of propylene oxide in the presence of methanol, during which propylene oxide is separated off from a mixture, comprising propylene oxide and methanol and the resulting mixture comprising methanol is worked up. The invention is characterised in that on working up, methanol is separated from a mixture containing methanol and methyl formate.
