Abstract: A mixture (M1) comprising an alkene and oxygen is worked up by a process in which (i) oxygen is removed from the mixture (M1) by a nondistillative method to give a mixture (M2) and (ii) the alkene is separated off from the mixture (M2) by distillation.

Abstract: The invention relates to a process for the preparation of a ferromagnetic chromium dioxide by converting oxides of trivalent and hexavalent chromium under a pressure of from 100 to 700 bar and at a temperature of from 200.degree. to 600.degree.C in the presence of water, an antimony modifier and acicular iron oxide particles or acicular iron particles in an amount of not more than 15% by weight comprising adding an antimony compound as a modifier in the form of a water-soluble salt in an amount of at least 0.1% by weight but less than 4% by weight, based on the resulting chromium dioxide and said iron oxide or iron particles to a mixture of hexavalent chromium oxide and water, adding trivalent chromium oxide thereto and subjecting the resultant mixture to said pressure and temperature, with a proviso that the water-soluble antimony compound contains at least one organic molecular moiety anion which is oxidized by the oxide of hexavalent chromium with the evolution of gas when said antimony compound is added to a mixture of said hexavalent chromium oxide and water. This process allows the preparation of ferromagnetic chromium dioxides having a high coercive force while at the same time reducing the amount of modifiers required for this purpose.

Abstract: The invention relates to a magnetic disc for track adjustment and amplitude control having at least one control track with magnetic control signals, this track being arranged in the central region of the recording area, and the control signals consisting of two different signals. The invention also relates to the geometric arrangement of the control signals in the track, their number, their amplitude, their frequency and their duration.

Abstract: An organic compound having at least one C-C double bond is epoxidized by means of hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, wherein a product mixture comprising alpha-hydroperoxyalcohols is reduced using at least one reducing agent. The process advantageously comprises at least the following steps: (i) reacting an organic compound having at least one C-C double bond with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to give a product mixture P1 comprising alpha-hydroperoxyalcohols; (ii) separating an epoxide formed in the reaction in step (i) and the unreacted organic compound having at least one C-C double bond from P1 or P1' to give a product mixture P2 or P2', where P2 comprises the alpha-hydroperoxyalcohols formed as by-product in the reaction in step (i) and P2' is largely free of alpha-hydroperoxyalcohols; (iii) treating P1 and/or P2 with at least one reducing agent so that the alpha-hydroperoxyalcohols are converted into corresponding glycols to give a product mixture P1' or P3.
