摘要： Medicinal white oils and medicinal paraffins are prepared from petroleum fractions containing aromatics and nitrogen, oxygen and sulfur compounds, e.g. light and heavy atmospheric gas oils, vacuum gas oils and residues, which have been pretreated in a first stage by acid treatment or catalytic hydrogenation, by hydrogenation in a second stage over a nickel-containing catalyst under from 50 to 200 bar and at elevated temperatures, by a process in which the catalyst used in the second stage and present in the oxide form is reduced with a hydrogen-containing gas, passivated and then again activated with hydrogen, before the hydrogenation to medicinal white oils or paraffins is carried out.

摘要： The invention relates to water-absorbing, cross-linked polymerizates which are in the form of a foam and which can be obtained by (I) foaming a polymerizable aqueous mixture which contains: (a) acid groups containing monoethylenically unsaturated monomers which are optionally neutralized; (b) optional other monoethylenically unsaturated monomers; (c) cross-linking agents; (d) initiators; (e) 0.1 to 20 wt. % of at least one surface active agent; (f) optionally at least one dissolving mediator; and (g) optional thickeners, foam stabilizers, polymerization chain transfer agents, fillers and/or cell nucleating agents. Fine bubbles of a gas which is inert against radicals causes foaming by dispersion in the polymerizable aqueous mixture. The inventive polymerizates can also be obtained by (II) polymerizing the foamed mixture by forming a hydrogel which is in the form of a foam, whereby at least 20 mol % of the monomers (a) containing acid groups are neutralized with tertiary alkanolamines and/or the free acid groups of the hydrogel in the form of a foam are neutralized with at least one alkanolamine to at least 20 mol % after the polymerization, and the water content of the polymerizate which is in the form of a foam is set at 1 to 60 wt. %. The invention additionally relates to a method for producing the inventive polymerizates and to the utilization thereof in sanitary articles which are used for absorbing body fluids and in bandaging material used for covering wounds.
