Abstract: Molding composition containing (a) 2,4,5-triketoimidazolidine precondensates containing terminal oxamide ester, urethane and/or isocyanate groups and (b) customary organic and/or inorganic fillers, which contains the triketo compound (a) in the form of an amorphous precondensate as a reactive filler and (c) at least one further reactive component of a binder from the group consisting of phenolic resins, amine resins, epoxide resins, polyester resins, hydrocarbon resins containing functional groups and/or polymerization resins containing functional groups; their use for manufacturing radiation-, light- and/or heat-resistant and/or abrasion-resistant shaped articles.

Abstract: Process for the removal of the residual sulfuric acid from the reaction mixture which has been obtained in the reaction of paraffin with sulfur dioxide, oxygen and water under irradiation by UV light and which has been freed from sulfur dioxide by degassing at an elevated temperature and from which the bulk of the sulfuric acid has been removed by concentration, by warming this concentrated product and adding as much of an alkali metal carbonate, peroxide, hydroxide, sulfate or sulfonate as is required to convert the residual sulfuric acid into an alkali metal bisulfate.

Abstract: The invention relates to a process and device for the production of highly concentrated spinning solutions from acrylonitrile polymers, where the dissolving is carried out in one step in a stirred mixing vessel, which has a disc-shaped stirrer rotating in a horizontal plane, the polymeric material to be dissolved and the solvent are metered in separately at room temperature into the stirring vortex which is formed, and the temperature of the solution being formed is maintained at a constant preset value in the range from 60 DEG to 120 DEG C. by controlling the peripheral velocity of the stirrer.

Abstract: Sepn. of organic components from waste gases produced in the mfr. of aromatic intermediates is effected by scrubbing with a 10-20C paraffinic hydrocarbon liq. (PHL) or diisopropylnaphthalene (DIPN) at 0-50 deg.C. DIPN includes C16H20 isomer mixts., with an av. molecular wt. of 210-215, a b.pt. of 290-300 deg.C and a flash point above 130 deg.C.

Abstract: Process for separating off organic constituents of exhaust gases (off-gases) which arise in the preparation of aromatic intermediates by absorption with scrubbing liquids, characterised in that the exhaust gas laden with pollutants is scrubbed at temperatures from 0 to 50@C with a scrubbing liquid of diisopropylnaphthalene or an isomeric mixture of the empirical formula C16H20, a mean molecular weight of 210-215, a boiling range of 290-300@C (DIN 51761) and a flash point above 130@C (DIN 51758).

Abstract: The process for separating organic constituents from waste gases, which arise in the chlorination or bromination of aromatics, by absorption by means of scrubbing fluids is characterised in that the waste gases are scrubbed at temperatures of 0-50@C with a scrubbing fluid composed of paraffin hydrocarbons having 10-20 carbon atoms and a melting point of at least 0@C.
