    摘要： The invention relates to an aqueous solution of modified silicates, wherein the solution is free of organic solvents and is obtained by reacting (a) an initially charge aqueous solution of silicates of the general formula M2O·nSiO2, wherein M is a cation from the group Li+, Na+, K+, NY4+, where Y is a hydrogen atom and/or an alkyl or alkenyl radical having 1 to 22 C atoms, and (b) at least one silane of the general formula R—(CH2)n—Si—(X)3 where X is independently a CH3, OCH3, OC2H5, OC3H7, OCOCH3, H or Cl radical, and R is a saturated or unsaturated, linear or branched or ring-shaped radical having at least one O and/or N atom and at least 2 C atoms, and n is a number between 1 and 3; at temperatures from 5 to 100° C., and wherein the alcohols arising from the conversion are subsequently removed. The aqueous solution of modified silicates is used to hydrophilize surfaces, particularly for high-temperature coatings.

    摘要： The addition of a nucleating or coalescing agent (e.g., urea) to liquid ammonia reduces the size and persistence of a deadly, fog-like cloud of ammonia droplets that tend to form when liquid ammonia is accidentally released to the atmosphere. In addition, high purity ammonia is obtained by evaporating ammonia from the ammonia- and nucleating agent-containing composition.

    摘要： Accidental spills of liquid ammonia can result in the formation of deadly, fog-like ovoids of ammonia droplets that persist for an appreciably time before dissipating. The addition of a coalescing additive such as urea to liquid ammonia reduces the size and persistence of the cloud that can form if the treated ammonia is accidentally released to the atmosphere. The potential for death and injury resulting from an accidental release of ammonia is thus substantially reduced.
