摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

标题:Method and system for production of antimicrobial disinfectant coatings using electrochemical synthesis
发明人：GORADIA PRERNA
权利人:GORADIA PRERNA
摘要:The present disclosure provides a method and system for producing antimicrobial compositions comprising transition metal ions which are generated electrolytically in aqueous solution; chelating agent and excipients; wherein the said ionic species thereby impart stability and longer shelf life and long-term efficacy. Owing to the neutral pH, colorless, odorless, tasteless, non-caustic, non-corrosive nature, the composition of example embodiments shall be used as surface disinfectant and food contact sanitizer and provides an unparalleled combination of high efficacy and low toxicity with instant kill and long-term efficacy. The specific combination of certain metals provides the ability to be extremely broad spectrum and thus works against virus, bacteria, fungi, mold, mildew and antibiotic resistant species as well.

摘要:The invention relates to the field of nanotechnologies and chemistry, and more precisely to metal carboxylates, which are widely used in perfumery, the food industry, medicine, agriculture and biology, as well as in the field of industrial organic synthesis. The ultra-pure aqueous solution of a metal carboxylate, in which the content of chloride, nitrate and sulphate ions does not exceed 0.0001 wt.% and which is produced by reacting carboxylic acid with nanoparticles of a metal, or metal oxide, or metal hydroxide, or a mixture thereof in an aqueous colloidal solution of the nanoparticles, is characterized in that the pH value of its acidity is in the range 2.5 - 8.0, preferably in the range 3.0 - 5.0, and the content of alkali metal contaminants does not exceed 0.01 wt.% of the content of the main metal. The pH value of the acidity of the ultra-pure aqueous solution of metal carboxylate is in the range 2.5 - 8.0, preferably in the range 3.0 - 5.0. This improves the quality of the metal carboxylate. With a pH value of less than 2.5 the solution contains an excessive amount of acid. With a pH value of more than 8.0 the probability of the formation of nanoparticles in the solution increases, particularly for carboxylates of copper and the noble metals. The total content of alkali metal contaminants does not exceed 0.01 wt.% of the content of the main metal. The invention addresses the problem of improving the quality of a carboxylate and the ecological purity thereof through the use, for the reaction with carboxylic acid and the preparation of a metal carboxylate solution, of nanoparticles of a metal, nanoparticles of a metal oxide and nanoparticles of a metal hydroxide which have acquired enhanced chemical activity during their creation as a result of the explosive dispersion of metal granules during spark discharges between them in water.
