Abstract: The problem addressed by the invention was to find an anionic polymerization inhibitor for cyanoacrylate adhesives containing one or more cyanoacrylates, stabilizers against anionic and radical polymerization and auxiliaries typically used in such adhesive systems which, besides a reliable inhibiting effect, would counteract any increase in the setting time after storage. This problem was solved by using 2-oxo-1,3,2-dioxathiolanes as inhibitors.

Abstract: The invention relates to a contact adhesive based on a polyurethane of at least one diisocyanate and at least one low molecular weight polyethylene glycol, the polyethylene glycol having a molecular weight of up to 2,000 and the polyurethane having a degrees of crystallization of less than 20%. The contact adhesive can be applied from the melt or from an aqueous solution or dispersion. Surprisingly, it is suitable not only for polar plastic surface, but above all for PE and PP surfaces and of course for paper. Accordingly, the contact adhesive is preferably useful for applying paper labels to PE bottles.

Abstract: When iron group, especially high nickel, metal alloys that contain substantial amounts of copper are pickled, a displacement coating of copper that is called a “copper kiss” often forms on the pickled surface from the dissolved copper ions in the pickling solution before the pickling solution can be rinsed away. Traditionally this has been removed by treatment with aqueous ammonia, an annoying and potentially hazardous reagent that in many instances requires expensive pollution abatement devices. In this invention, copper kiss is equally effectively removed by treatment with a mixture of sulfuric acid and hydrogen peroxide, optionally also containing hydrofluoric acid.

Abstract: The invention relates to liquid multiphase, essentially CFC-free detergents with at least two continuous phases. The detergents have at least one aqueous phase (I) and a non-aqueous liquid phase (II) that is immiscible with phase (I), and can be temporarily transformed into an emulsion by shaking. They also contain an anionic and/or non-ionic surfactant and are suitable for use in a method for cleaning hard surfaces, especially glass. According to said method, the inventive detergent is shaken to produce the temporary emulsion and applied to the surface to be cleaned in quantities of 1.5 to 10 g per m{circumflex over ( )}2, preferably by spraying. The surface is then cleaned, optionally by wiping with a soft, absorbent object.

Abstract: A process for recovering isoflavone values from a biomass in which the isoflavone values are extracted from the biomass with a selective solvent for the isoflavone values, solid isoflavone values and the selective solvent are contacted with a nonsolvent or antisolvent for the isoflavone value which is miscible with the selective solvent. Optionally the nonsolvent or antisolvent is admixed with water during the contact with the solid isoflavone values to improve the purity and recovery of the solid isoflavone values.

Abstract: A low-monomer PU prepolymer containing free NCO groups which is obtained from polyhydric alcohols and diisocyanates differing in their reactivity and which is distinguished by the ratio of the NCO groups of the partly slower-reacting diisocyanate to the NCO groups of the faster-reacting diisocyanate. It is greater than 6:1. Nevertheless the prepolymer according to the invention cures more quickly than a known prepolymer predominantly containing fast-reacting NCO groups. In a preferred embodiment, TDI is used as the partly slower-reacting diisocyanate while MDI is used as the faster-reacting diisocyanate. The prepolymer is produced in two stages. The prepolymer according to the invention is suitable for bonding plastic articles, metals and paper, especially films. The accelerated absence of migration is particularly noticeable in this regard.
