Abstract: 87/F 398 K : A process for the separation of undesired organic ingredients from waste gases which are formed in the preparation of aromatic intermediates which comprises washing the waste gases with a washing liquid comprising a) paraffinic hydrocarbons having from 10 to 20 carbon atoms or b) diisopropylnaphthalene or a mixture of isomers thereof having the sum formula C16H20, an average molecular weight in the range of from 210 to 215, a boiling range in the range of from 290 to 300.degree.C (according to DIN 51 761) and a flash point above 130.degree.C (according to DIN 51 758) at a temperature in the range of from 0 to 50.degree.C to remove the said undesired organic ingredients.

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 or in the form of a composite of a1) a 2,4,5-triketoimidazo-lidine precondensate pulp and a2) a pulp of other fiberforming polymers or, instead of this pulp a2), fibers made of 2,4,5-triketoimidazolidines and/or other materials 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 heatresistant and/or abrasion-resistant shaped articles, and a process for preparing a composite of 2,4,5-tri-ketoimidazolidine precondensate pulp and fibers by spraying a solution of a triketoimidazolidine precondensate in organic solvents together with fibers or injecting a solution of the precondensate into a suspension of fibers in a coagulating bath.
