| 应用领域 | Uses: Used as a mordant in dyeing、a soldering flux、a fertilizer、and a pickling agent、also used in the dry battery、electroplating、plastics、food processing、and pharmaceutical industries、a large amount of fume may be generated in galvanizing operations、[ACGIH]、Steel Producing [Category: Industry]、Electroplating [Category: Plate]、Soldering [Category: Heat or Machine]、Applying metallic patinas [Category: Hobbies]、Mesh Heading: diuretics、expectorants、For ammonium chloride (USEPA、OPP Pesticide Code: 129014) there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、As a flux in zinc and tin plating、electrolytic refining of zinc、etching solutions in manufacture of printed circuit boards、in dry and Leclanche batteries、as a nitrogen source for fertilization of rice and wheat、manufacturing of explosives、flame suppressant、hardener for formaldehyde-based adhesives、mordant for dyes and printing.、Dry batteries、mordant (dyeing and printing)、soldering flux、manufacturing of various ammonia compounds、fertilizer、pickeling agent in zinc coating and tinning、washing powders、melt-retarding snow treatment、production of urea-formaldehyde resins and adhesives、bakery products.、For more Uses (Complete) data for AMMONIUM CHLORIDE (23 total)、please visit the HSDB record page.、Use Classification: Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients、Food Additives -> FLOUR_TREATMENT_AGENT、YEAST_FOOD -> JECFA Functional Classes、Cosmetics -> Buffering、Viscosity controlling、Industry Uses: Lubricating agent、Other、Processing aids not otherwise specified、Plating agent、Flux agent、Soil amendments (fertilizers)、Ion exchange agent、Not Known or Reasonably Ascertainable、Intermediate、Anti-scaling agent、Processing aids、specific to petroleum production、Etching agent、Consumer Uses: Processing aids、Sealant (barrier)、pH regulating agent、Household Products: Information on 153 consumer products that contain Ammonium chloride in the following categories is provided:、• Auto Products、• Commercial、Institutional、• Home Maintenance、• Inside the Home、• Personal Care、Methods of Manufacturing: By the following processes: (1) the ammoniacal liquid obtained from the destructive distillation of coal is neutralized with HCl and the crude product subsequently is purified、(2) the vapors of ammonia from synthetic processes are absorbed in HCl、and (3) as byproduct in the Solvay process for sodium bicarbonate.、Double-decomposition processes all involve the reaction of sodium chloride、the cheapest chlorine source、with an ammonium salt. The latter may be supplied directly、or generated in situ by the reaction of ammonia and a supplementary ingredient. Ammonium chloride and a sodium salt are formed. The sodium salt is typically less soluble and is separated at higher temperatures、ammonium chloride is recovered from the filtrate by cooling.、Ammonium chloride is made as a by-product of the classic Solvay process、used to manufacture sodium carbonate. The method involves reaction of ammonia、carbon dioxide、and sodium chloride in water. Sodium bicarbonate precipitates from solution and is recovered by filtration. Ammonium chloride is then crystallized from the filtrate、separated、washed、and dried. The exact proportion of ammonium chloride recovered depends on the relative demands for sodium carbonate and ammonium chloride. If economic conditions require、part of the ammonia can be recovered and returned to the brine-ammoniation step by distillation of the ammonium chloride solution in the presence of lime. The spent calcium chloride liquor、a final product in manufacture of sodium carbonate by the ammonia-soda process、can also be used to obtain ammonium chloride. This liquor is treated with ammonia and carbon dioxide. Calcium carbonate is removed by filtration leaving an ammonium chloride solution.、Ammonium sulfate、a readily available by-product、has been much used to make ammonium chloride by a double decomposition reaction with sodium chloride. The ammonium sulfate and sodium chloride are simultaneously dissolved、preferably in a heel of ammonium chloride solution. The sodium chloride is typically in excess of about 5%. The pasty mixture is kept hot and agitated vigorously. When the mixture is separated by vacuum filtration、the filter and all connections are heated to avoid crust formation. The crystalline sodium sulfate is washed to remove essentially all of the ammonium chloride and the washings recycled to the process. The ammonium chloride filtrate is transferred to acid resistant crystallizing pans、concentrated、and cooled to effect crystallization. The crystalline NH4Cl is washed with water to remove sulfate and dried to yield a product of high purity.、Because of the availability of by-product ammonium salts、the double decomposition routes are usually more favorable economically for ammonium chloride manufacture. However、where surplus hydrogen chloride is available、the direct neutralization process has been used. The reaction is very exothermic and the heat generated is used to evaporate a large part of the water present when aqueous hydrochloric acid is used. Batch or continuous crystallization is then employed to recover the ammonium chloride.、Impurities: Principal impurity is NaCl.、Formulations、Preparations: Contains 99.5-99.8% NH4Cl、principal impurity is NaCl、exists in two temperature dependent crystal modifications.、Parenteral: For injection、concentrate: 26.75 |
