        Ammonium fluoride Chemical Properties,Uses,Production

        Ammonium hydrogen fluoride

        At room temperature, ammonium hydrogen fluoride appears as white or colorless orthorhombic crystal with slight sour. It is poisonous! It is slightly soluble in alcohol, easily soluble in cold water while subjecting to decomposition in hot water. Its aqueous solution is strongly acidic. It is obtained through the neutralization between the anhydrous hydrofluoric acid and ammonia. It can corrode glass and is corrosive to the skin. It can be used as a chemical reagent, glass etching agent (with participation of hydrofluoric acid), disinfectants and preservatives in fermentation industry, solvent for making metal beryllium via beryllium oxide and surface treatment agent of silicon steel sheet. It can also be used for the manufacturing of ceramics, magnesium alloy, the cleaning and scaling of boiler feed water systems and steam generating system as well as the acid treatment agent for oil sand. It is also used as the component of alkylation and isomerization catalyst.
        The production process of ammonium hydrogen fluoride is generally first generating ammonium fluoride followed by further sending through hydrogen fluoride to generate ammonium hydrogen fluoride. If not properly managed, it will become a mixture of ammonium fluoride and ammonium hydrogen fluoride with ammonium fluoride being easily decomposed into ammonium hydrogen fluoride.

        Toxicity

        This product is toxic. The operator must wear protective equipment. See the remaining protective measures in the part of ammonium hydrogen fluoride.

        Chemical Properties

        It appears as colorless phyllodes or needle-like crystals and forms hexagonal columnar crystals after being subject to sublimation. It is easily deliquescent. It is easily soluble in water with aqueous solution being acidic. It is soluble in alcohol but insoluble in acetone and liquid ammonia.

        Uses

        It can be used as glass etching agent, the chemical polishing agent on the metal surface, preservatives and disinfectants of brewing and fiber mordant as well as for extracting rare metals.
        It can be used as reagents for the analysis, masking agents and preservatives.
        It can be applied to wood preservation, glass engraving and precipitation agent for the complexometric titration of the aluminum, extraction of rare elements as well as spot analysis of zirconium.

        Production method

        Liquid-phase method: to lead or plastic container, put certain amount of hydrofluoric acid. Cool water in the outer container and slowly introduce ammonia gas under stirring until the pH value of reaction solution reaches about 4. The reaction liquid further goes through cooling and crystallization, centrifugation, air drying to obtain ammonium fluoride products.

        Acute toxicity

        Intraperitoneal-rat LD50: 31 mg/kg; subcutaneous-Fox LDL0: 280 mg/kg.

        Flammability and hazard characteristics

        It release flammable ammonia gas upon thermal decomposition; in case of acid, it releases toxic hydrogen fluoride gas.

        Storage characteristics

        Treasury: ventilation, low-temperature and drying; store it separately from acids, bases, food and CLF3.

        TWA 2.5 mg (fluorine)/cubic meter; STEL 5 mg (fluorine)/cubic meter.

        Chemical Properties

        Ammonium fluoride,NH4F, is a white crystalline salt that is soluble in cold water. It is unstable and emits a strong odor of ammonia. Ammonium fluoride is used in etching glass,preserving wood,and in the textile industry as a mordant.

        Chemical Properties

        Ammonium fluoride is a white crystalline solid.

        Uses

        Etching and frosting glass; as antiseptic in brewing beer; preserving wood; in printing and dyeing textiles; as mothproofing agent.

        Definition

        ChEBI: A fluoride salt having ammonium (NH4+) as the counterion.

        General Description

        Ammonium fluoride is a white crystalline solid. Ammonium fluoride is soluble in water. Ammonium fluoride is noncombustible. Ammonium fluoride is corrosive to aluminum. Ammonium fluoride is used in chemical analysis, in brewing, and as a preservative for wood.

        Air & Water Reactions

        Dissolves in water and forms dilute solution of hydrofluoric acid. May corrode glass, cement, and most metals [USCG, 1999]. Water soluble.

        Reactivity Profile

        Salts, basic, such as Ammonium fluoride, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

        Hazard

        Corrosive to tissue.

        Health Hazard

        Inhalation of dust may cause irritation of respiratory system. Ingestion is harmful; readily soluble fluorides may be fatal if relatively small quantities are swallowed. Contact with eyes causes local irritation of the mucous membrane. Contact with skin may cause burns. High concs. of fluorine in the urine have been reported following skin contact.

        Safety Profile

        Poison by subcutaneous and intraperitoneal routes. See also FLUORIDES. When heated to decomposition it emits very toxic fumes of F-, NO,, and NH3. Incompatible with ClF3

        Potential Exposure

        Ammonium fluoride is used in printing and dyeing textiles; glass etching, moth-proofing and wood preserving; in analytical chemistry, agriculture, antiseptic in brewing.

        Shipping

        UN2505 Ammonium fluoride, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

        Incompatibilities

        Acids, alkalis, chlorine trifluoride. Corrodes glass, cement, most metals.

        Waste Disposal

        Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
