Abstract: Peroxide treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where a peroxide activator is stabilized without the presence of phosphorus-containing compounds (e.g., phosphorus-containing stabilizers), through use of a nonionic surfactant (e.g., alkoxylated alcohol) with a cloud point above 45° C. Use of a single nonionic surfactant, or a surfactant package that may include a small fraction (e.g., less than 0.5%) of sodium lauryl sulfate or another anionic surfactant has been found to be surprisingly effective at stabilizing the peroxide/activator combination, even where water content may be 85% or greater. The composition can have a pH of 5 or less (e.g., 3 to 4). The composition may be free of other anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, magnesium salts, borates and boric acid, hydroxides, chelating agents, various amine oxides, ethoxylated amines, and the like.

Abstract: A method for semiconductor wafer scribing utilizing perforated metal areas in the scribe regions. In one form, a method for fabricating a semiconductor device includes forming a plurality of semiconductor die (12) on a semiconductor wafer (10) such that the die are separated from one another by scribe regions (13). A test structure (14) is formed within one of the scribe regions and includes a perforated probe pad (16). In one embodiment, the probe pad is perforated by a plurality of slots (18). The perforations in the probe pad aid in scribing the semiconductor wafer by preventing metal lift-off which often occurs when cutting metal areas.

Abstract: Processes are described wherein formaldehyde or formic acid and similar materials are oxidized to produce carbon dioxide and water by contact with oxygen in the presence of a noble metal catalyst on a carbon support that is protected from poisonous amines by a polymer coating.

Abstract: A method for preparing thiophenolic compounds is described comprising reacting a phenol and hydrogen sulfide in the presence of a vanadia catalyst. It is preferred to carry out the process of this invention at low pressures, i.e. at pressures lower than 100 psi, atmospheric pressure being very suitable, although the process is operable at subatmospheric pressures. Preferred phenols, catalysts and reaction conditions are also described.

Abstract: A process for production of orthophenylphenol is disclosed. More specifically, the invention relates to the conversion of phenol or diphenyl ether into orthophenylphenol in a two-stage process in which dibenzofuran is an intermediate.

Abstract: A method for preparation of heterocyclic fused ring compounds by dehydration and dehydrogenation of certain phenolic compounds in the presence of water vapor and in the presence of a cerium oxide catalyst is disclosed. Preferred phenolic compounds, catalytic materials, and reaction conditions also are described.

Abstract: The present invention relates to a process for the preparation of orthophenylphenol and derivatives thereof, specifically by the reaction of dibenzofuran and its derivatives with hydrogen, at elevated temperatures, in the presence of a catalyst comprised of one or more Group VIII elements dispersed on a porous magnesia support.
