Adsorption of chlorine into aqueous sodium hydroxide solutionsThe rates of absorption of pure chlorine into aqueous sodium hydroxide solutions of various concentrations were measured at 30° C using a liquid-jetdoi:10.1016/0300-9467(73)85009-9H. Hikita...
Chlorine dioxide (ClO2) is an orange-yellow gas with a liquefaction temperature of 9.7°C at atmospheric pressure. It is explosive in either its gaseous or pure liquid state. Dilute aqueous solutions are not explosive. Two principal methods are used for the preparation of aqueous solutions of c...
Effect of aqueous chlorine dioxide (ClO) treatment on browning of fresh-cut lotus root (FLR) was investigated to explore the feasibility to apply ClO for b... J Du,Y Fu,N Wang - LWT - Food Science and Technology 被引量: 199发表: 2009年 Use of Chlorine Dioxide for Controlling Microorgan...
On an industrial scale an aqueous solution of chlorine dioxide is made by passing nitrogen dioxide up a tower packed with a fused mixture of aluminum oxide and clay, down which a solution of sodium chlorate flows. 7.6 Hazard Explodes when heated or by reaction with organic materials. Very ...
AR 50-6 deals specifically with the shipment of chemical agents. Shipments of agent will be escorted in accordance with AR 740-32. Purification Methods Pass the gas in succession through aqueous KMnO4, dilute H2SO4, conc H2SO4, and a drying tower containing Mg(ClO4)2. Or bubble it ...
the purification of water and as a bleach in the flour and wood-pulp industry. On an industrial scale an aqueous solution of chlorine dioxide is made by passing nitrogen dioxide up a tower packed with a fused mixture of aluminum oxide and clay, down which a solution of sodium chlorate ...
Preferably, the metal content is 7 wt % or less with respect to the total weight of the annealed sample. Preferably, these components are added after a first annealing step of the catalyst by impregnation with an aqueous solution containing the precursor compounds. Preferably, the such ...
Substituted benzyl and benzal chlorides are also converted into the corresponding benzotrichlorides when they are treated with tetrachloromethane or hexachloroethane and aqueous sodium hydroxide in the presence of a phase transfer catalyst (PTC) by a process which probably involves nucleophilic attack ...
production of chlorine and sodium hydroxide solution by electrolysis of aqueous solutions of sodium chlorideThe crude brine, after removal of alkaline-earth and heavy metals by treatment with alkaline Na carbonate solns., is led to the cells in a quantiy to replace the NaCl consumed, and a part...
aqueous suspension or solution to be about pH 6.5 or less. Typical treating times are about 10-40 minutes. Moreover, the amount of chlorine necessary to decolorize the dyestuff can be calculated, or adjusted, to provide an amount slightly in excess thereof, all in accordance with the present...
