摘要:Simple and economic electrolytic synthesis of peracetic acid is performed, and cold drink containers, etc., are sterilized/cleaned with an aqueous solution of peracetic acid thus obtained. Peracetic acid is electrolytically synthesized from acetic acid and/or acetate and an oxygen-containing gas as starting materials in the presence of a solid acid catalyst in an electrolytic cell. An object to be cleaned is sterilized/cleaned with an aqueous solution of peracetic acid thus obtained. Peracetic acid can be simply obtained at a reduced cost. The sterilizing/cleaning of an object to be cleaned with peracetic acid can be conducted efficiently.

标题:Electrochemical synthesis of ammonia
发明人：DENVIR ADRIAN; MURPHY OLIVER J; CISAR ALAN; ROBERTSON PRISCILLA; USELTON KYLE
摘要:A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.

标题:Fluorosulphonated elastomers with low glass transition based of vinylidene fluoride

摘要:The present invention describes the synthesis of new sulforated fluorinated elastomers having very low glass transition temperatures (Tg), a good resistance to bases, oils and fuels and good properties of workability. These elastomers contain, by way of example, from 80 to 60 mole % of vinylidene fluoride (VDF) and 20 to 40 mole % of perfluoro(4-methyl-3,6-dioxaoct-7-ene) sulfonyl fluoride (PFSO2F). In this case, they are prepared by radical copolymerisation of VDF and PFSO2F in the presence of different organic initiators, for example, peroxides, peresters or diazo compounds.

标题 :Ion-exchange structures of copolymer blends useful in electrolytic cells
发明人：MOLNAR CHARLES J; PRICE EDWARD H; RESNICK PAUL R

摘要:Ion-exchange films, membranes and laminar structures incorporating a layer of a blend of a first fluorinated polymer which contains sulfonyl groups in ionizable form and a second fluorinated polymer which contains carboxylic acid functional groups, when used to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency and low power consumption. They can be made by synthesis of precursor polymers in melt-fabricable form, blending, fabrication of the film, membrane or laminar structure, and hydrolysis of the functional groups to ionizable form, such as the free acid form or alkali metal salt thereof.
