摘要:
The present invention provides a method of reducing the pathogen content of sewage sludge comprising (a) adding to the sludge an effective amount of a phosphorous-containing compound and (b) keeping the phosphorous-containing compound in contact with the sludge for a sufficient time to reduce the amount of pathogens present in the sludge by an amount equivalent to a logarithmic reduction of 2 or more.
摘要:
Modified and insoluble starches are utilized for eliminating natural organic substances/contaminants from liquids and in particular from liquids used for food applications, such as drinking water, beverages, fruit juices or syrups, as well as natural water, industrial process water, or wastewater.
摘要:
A synergistic composition comprising a THP salt and a biopenetrant, in which the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or diphosphonated unsaturated carboxylic acid group or having such monomers incorporated into the polymer backbone. This composition acts synergistically to enhance the biocidal efficacy of the THP salt against both planktonic (free-swimming) and sessile (attached) bacteria, and also acts synergistically to enhance the efficacy of the THP salt in the dissolution of iron sulphide scale.
摘要:
The present invention relates to a method of preventing or alleviating the problems associated with corrosion and to novel formulations for use in such a method.
摘要:
The invention relates to a diastereoselective process for the preparation of olefins by the Horner-Wadsworth-Emmons reaction which consists in reacting a specific phosphonate improve the diastereoselectivity at all temperatures including at ambient temperature, with a carbonyl derivative in the presence of a base in an appropriate solvent.
摘要:
The present invention relates to the use of dendrimers with monophosphonic or bisphosphonic terminations in order to stimulate the growth of cell cultures or to activate cells in culture.
摘要:
A phosphonium compound embedded in a matrix substrate wherein the phosphonium compound is selected from a group consisting of tris (hydroxyorgano) phosphine (THP), a THP+ salt (tetrakis (hydroxyorgano) phosphonium salt) or a condensate of THP and a nitrogen containing compound. The compound may be used to reduce the number of microorganisms in industrial systems and may also be used to reduce iron carbonate or iron, lead and zinc scale deposits.
摘要:
Mixtures of three types of linear, branched or cyclic phosphates are useful flame retardants, especially for thermoplastic resins or as functional additives in polymer matrices.
摘要:
Bisphosphines are prepared by reacting a phosphine with a dihalide in the presence of an acid; characteristically, bisphosphonium compounds are initially formed and then converted into the bisphosphines.
