摘要： A process for treating solutions of a hydroxylammonium salt containing excess acid which comprises:a) mixing the hydroxylammonium salt containing excess acid with a hydroxylammonium solution containing free hydroxylamine to produce a solution of the hydroxylammonium salt substantially free of excess acid,b) contacting a portion of the solution of the hydroxylammonium salt substantially free of excess acid with a weak base ion exchange resin to produce the hydroxylammonium solution containing free hydroxylamine, and,c) recycling the hydroxylammonium solution containing free hydroxylamine to step a).The process minimizes the decomposition of the hydroxylammonium salt solution and produces high purity hydroxylammonium nitrate solutions without directly contacting excess nitric acid with ion exchange resins. In addition to hydroxylammonium salts, the process can be used to treat any nitrate salt of an anine weak base which contains excess nitric acid.

摘要： A process for removing chlorine gas from the tail gas stream of a chlor/alkali plant or other chemical processes comprising the steps of: (a) contacting a chlorine-, hydrogen-, and carbon dioxide-containing tail gas stream with a zeolite molecular sieve having a molecular pore diameter greater than the molecular diameter of the carbon dioxide and hydrogen and smaller than the molecular diameter of chlorine so that at least a portion of the carbon dioxide is absorbed onto the molecular sieve, and thereby producing a purified tail gas stream that contains substantially all of the chlorine and hydrogen values and a reduced amount or no amount of carbon dioxide values; and (b) contacting the purified tail gas stream with an aqueous sodium hydroxide scrubbing solution in order to remove substantially all of the chlorine values from the purified tail gas stream, whereby producing a purified sodium hypochlorite solution that is substantially free of sodium carbonate.

摘要： A process is described for removing available chlorine from a depleted recirculating anolyte brine of a chlor-alkali cell. After the spent brine is removed from the cell, and typically after dechlorination, it is reacted with an amount of an organic hydroxyl moiety-containing compound soluble in said brine for a residence time sufficient to substantially reduce the residual dissolved chlorine and hypohalite ion remaining in said brine prior to resaturation and reuse in said cell. Suitable hydroxyl moiety-containing compounds include alcohols and saccharides.

摘要： A method of heat sealing together two untreated layers of a sulfonated perfluorovinyl ether ion exchange diaphragm or membrane material having pendant groups predominantly in the sulfonamide form by placing a layer of untreated sulfonated perfluorovinyl ether material having pendant groups predominantly in the sulfonic acid form between the sulfonamide layers to create a "sandwich". The preferred heat sealing involves applying from 1 to 5, and preferably from 3.5 to 5.0 kg/cm.sup.2 pressure at from 260.degree. to 350.degree. C. and preferably from 280.degree. to 320.degree. C. for from 3.5 to 7.5, and preferably from 3.5 to 5.0 seconds to this "sandwich". It had been previously taught that such untreated sulfonamide layers could not be heat sealed together. The novel heat sealing technique of this invention enables fabrication of a cathode-membrane unit using ion exchange membranes having such a sulfonamide layer facing the cathode of an electrolytic cell.
