  • Patent number: 12168624
    Abstract: The present disclosure provides an improved scale inhibiting formulation that is effective, environmentally friendly, and does not add any organic compounds or traditional polymeric compounds to treated water. The scale inhibiting composition includes molecular clusters of polyammonium bisulfate (PABS), which can interact physically, chemically, or physio-chemically with one or more ions in the water or water-containing system being treated. That interaction inhibits scale accretion and/or removes previously formed scale.

  • Publication number: 20140107230
    Abstract: The invention relates to a wetting agent and to its use. The wetting agent comprises a biodegradable surfactant which is present in a solution in water, and allows foam to be formed during the electroplating application. The stability of the foam formed allows retarded release of the hydrogen that is formed during the galvanic application. This wetting agent is stable to degradation and has no effect at all on the electroplating application. The wetting agent of the invention exhibits good biodegradability. The level of consumption of the wetting agent is comparable with using PFOS-containing wetting agents. The wetting agent provides a simple, eco-friendly and time cost-effective alternative to the known PFOS-free wetting agents, with the wetting agent of the invention exerting no effect on the outcome of the electroplating application, by virtue of reduced wetting agent consumption and by virtue of the chemically-inert properties of said wetting agent.

  • Patent number: 8211949
    Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.
