    摘要： Activated hydrogen peroxide disinfecting compositions are provided especially for low-foaming applications. A concentrate for dilution by an end-user is provided, which includes a hydrogen peroxide source, a non-surfactant organic sulfonic acid or salt thereof, a non-ionic surfactant, and an optional organic acid. Also provided is a ready-to-use hydrogen peroxide, disinfectant solution including a biocidal amount of hydrogen peroxide, a non-surfactant organic sulfonic acid or salt thereof, a non-ionic surfactant, water as solvent and an optional organic acid. An end-user can disinfect a surface of microorganisms by contacting the surface with the disinfecting composition for an amount of time effective to kill a majority of the microbes located on the surface.

    摘要： Disclosed are compositions for stabilizing a source of active halogen in aqueous solution. The compositions comprise (i) at least one substituted N-hydrogen compound, such as 5,5-dimethylhydantoin, and (ii) at least one additional nitrogen compound selected from ammonia, ammonium salts, and nitrogen compounds containing no carbon-hydrogen bonds, the molar ratio of (i) and (ii) being in the range of 50:1 to 0.02:1. Active halogen-containing aqueous solutions stabilized by the above compositions are particularly useful for controlling microbial and planktonic growth in aqueous systems such as process liquids in the pulping or papermaking industry. The compositions are also useful in reducing the corrosivity of halogen-containing solutions.

    摘要： Applicant has discovered an in situ method of preparing quaternary ammonium methocarbonate salts and quaternary ammonium alkylcarbonate salts in high yield from tertiary amines, methanol, and at least one of a cyclic carbonate, an aliphatic polyester (such as a polycarbonate), or an ester (such as a carbonate ester), and their subsequent conversion to quaternary ammonium bicarbonates, quaternary ammonium carbonates or both in a one-pot reaction. According to one embodiment of the invention, the method includes reacting an amine and methanol with at least one of a cyclic carbonate and an aliphatic polyester to yield a quaternary ammonium methocarbonate. This method does not produce or require the handling of corrosive quaternary ammonium hydroxides. Another embodiment is a method of preparing quaternary ammonium alkylcarbonate salts by reacting tertiary amines, methanol, and an ester. The quaternary ammonium methocarbonate or alkylcarbonate can be converted to the corresponding bicarbonate, carbonate, or mixture thereof by methods know in the art.
