Abstract: A disposable, absorbent diaper comprising a topsheet, a liquid impervious backsheet associated with the topsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core has a dusting layer of mechanical pulp fibers, a continuous primary layer of mechanical pulp fibers containing from about 8% to about 60%, on a total primary layer dry weight basis, of discrete particles of polymeric gelling material, and a water-permeable core reinforcing layer disposed between the dusting layer and the primary layer. The mechanical pulp fibers, preferably chemithermomechanical pulp fibers, have an average fiber length of at least about 1.9 mm and are in a highly disintegrated condition.

Abstract: The present invention provides absorbent articles, such as disposable diapers, which utilize a particular type of stiffened cellulose fibers and a particlar type and form of polymeric gelling agent particles to enhance the absorbency characteristics of such articles. In these articles, the gelling agent material, combined in particulate form of a certain size with stiffened cellulose fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, generally larger, fluid acquisition/distribution layer which also contains stiffened cellulose fibers and gelling agent particles of a certain size. This lower fluid storage layer is generally positioned toward the front of the absorbent article. Absorbent articles of this type can be fashioned into especially thin, compact, nonbulky diapers.

Abstract: Halogenated phenolic compounds are prepared by forming a low melting point complex of the phenolic compound and contacting the low melting point complex with a halogenating agent under halogenating conditions.

Abstract: Products from the heterogeneously catalyzed oxidative coupling of 2,6-ditertiarybutylphenol are prepared in high yield by the use of an unreactive, non-polar liquid reactive medium.

Abstract: The decomposition of chlorinated phenols, especially pentachlorophenol, during exposure to high temperatures (e.g., storage and distillation) is markedly reduced by incorporating into the molten chlorinated phenol at least about 0.25 percent by weight of said impure chlorinated phenol of at least one monohydric primary alcohol having at least 14 carbon atoms, one hydroxyl group, and devoid of any other heteroatoms or ether linkages; selected from the group consisting of straight-chain or branched monohydric primary alcohols or a mixture of said straight-chain or branched monohydric primary alcohols.

Abstract: In an improved process for preparing chlorinated phenol by the reaction of molten phenol with chlorine in the presence of a Friedel-Crafts catalyst, the improvement comprises adding to the molten chlorinated phenol product, immediately on completion of the chlorination process, at least 0.5 weight percent of a glycol ether thereby inhibiting dioxin formation, inhibiting decomposition of the technical grade chlorinated phenol and most importantly, imparting mold release properties to the final product which is cast in corrosion-resistant molds, preferably stainless steel or plastic-lined steel molds.
