    • Overviw of Active Pharmaceutical Ingredients Zinc chloride

    Zinc chloride is the name of chemical compounds with the formula ZnCl2and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. ZnCl2 itself is hygroscopic and even deliquescent. Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. Zinc chloride finds wide application in textile processing, metallurgical fluxes, and chemical synthesis. No mineral with this chemical composition is known aside from the very rare mineral simonkolleite, Zn5(OH)8Cl2·H2O.

    • Application of Active Pharmaceutical Ingredients Zinc chloride

    Once known as "butter of zinc," zinc chloride is a versatile chemical suitable for aiding many aspects of daily life. Zinc chloride easily binds itself to water, known as hygroscopy, so it is an ideal compound for maintaining water purity. Zinc chloride is also a conductor of electricity, making it a useful electrical compound, and it supplements the amount of zinc in both plants and animals, making it an important dietary compound.


    1. As a metallurgical flux


    • Zinc chloride has the ability to react with metal oxides (MO) to give derivatives of the formula MZnOCl2. This reaction is relevant to the utility of ZnCl2 solution as a flux for soldering — it dissolves oxide coatings exposing the clean metal surface. Fluxes with ZnCl2 as an active ingredient are sometimes called "tinner's fluid".

    • Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the liquid ceased to evolve hydrogen; for this reason, such flux was once known as "killed spirits". Because of its corrosive nature, this flux is not suitable for situations where any residue cannot be cleaned away, such as electronic work. This property also leads to its use in the manufacture of magnesia cements for dental fillings and certain mouthwashes as an active ingredient.


    2. In organic synthesis


    (1) In the laboratory, zinc chloride (Silzic) finds wide use, principally as a moderate-strength Lewis acid. It can catalyze (A) the Fischer indole synthesis, and also (B) Friedel-Crafts acylation reactions involving activated aromatic rings.


    (2) Related to the latter is the classical preparation of the dye fluorescein from phthalic anhydride and resorcinol, which involves a Friedel-Crafts acylation. This transformation has in fact been accomplished using even the hydrated ZnCl2 sample shown in the picture above.


    (3) Hydrochloric acid alone reacts poorly with primary alcohols and secondary alcohols, but a combination of HCl with ZnCl2 (known together as the "Lucas reagent") is effective for the preparation of alkyl chlorides. Typical reactions are conducted at 130 °C. This reaction probably proceeds via an SN2 mechanism with primary alcohols but SN1 pathway with secondary alcohols.


    (4) Zinc chloride is also a useful starting reagent for the synthesis of many organozinc reagents, such as those used in the palladium catalyzed Negishi coupling with aryl halides or vinyl halides.In such cases the organozinc compound is usually prepared by transmetallation from an organolithium or a Grignard reagent.


    3. In textile and paper processing


    Concentrated aqueous solutions of zinc chloride (more than 64% weight/weight zinc chloride in water) have the interesting property of dissolving starch, silk, and cellulose. Thus, such solutions cannot be filtered through standard filter papers. Relevant to its affinity for these materials, ZnCl2 is used as a fireproofing agent and in fabric "refresheners" such as Febreze. Vulcanized fibre is made by soaking paper in concentrated zinc chloride.


    4. Disinfectant


    Historically, a dilute aqueous solution of zinc chloride was used as a disinfectant under the name "Burnett's Disinfecting Fluid". It is also used in some commercial brands of antiseptic mouthwash.


    5. Skin cancer treatment


    (1) Zinc chloride has been used in alternative medicine to cause eschars, scabs of dead tissue, in an attempt to cure skin cancers. Various products, such as Cansema or "black salve", containing zinc chloride and sold as cancer cures have been listed by the U.S. Food and Drug Administration (FDA) as fake with warning letters being sent to suppliers.


    (2) Numerous reports in medical literature describe serious scarring and damage to normal skin by escharotic substances. Given these side-effects, its use in treatment is not warranted as there are much safer and more effective alternatives, such as radiation therapy and Mohs surgery.


    6. Properties


    Zinc chloride is a white crystalline granule. It usually has an acrid smell but is sometimes odorless. Zinc chloride is stable when stored and used under normal conditions, but when heated to decomposition, it can release toxic chlorine and zinc oxide fumes. Zinc chloride fumes when it establishes contact with cyanides, sulfides or potassium, which can cause fires or explosions. Its fumes are corrosive to metals.


    7.Industrial Applications


    Zinc chloride is used in dry cell batteries both as an electrolyte, moisture absorbent and corrosion inhibitor. It is used in fluxes for soldering, galvanizing and tinning. As an excellent emulsion breaker, zinc chloride is used to separate oil from water. It is also used as a packer fluid in oil and gas wells. Zinc chloride is put to use as an inhibitor in potable water treatment plants, cooling towers, and gas and oil wells.


    • Sources of Exposure

    Exposure sources of zinc chloride in the workplace include working conditions including copper plating of iron, etching metals and soldering with fluxes having zinc chloride as well as galvanizing iron, arc welding of steel and iron pipes, vulcanizing and reclaiming methods in rubber manufacture and in the manufacture of smokescreen for military purposes. Proper ventilation and personal protective gear are necessary for ensuring the workers and other people in the area are not exposed to toxic fumes of zinc chloride.


    • Potential Health Hazards

    Zinc chloride can destroy tissues of the upper respiratory tract and mucous membranes, in inhaled. If zinc chloride is ingested into the human system, symptoms such as burning sensation, cough, laryngitis, shortness of breath, wheezing, headache and vomiting will manifest. When zinc chloride fumes contact skin, it can lead to skin burn, ulceration and irritation. If the fumes contact eyes, it can lead to reddish eyes, blurred vision and pain. If zinc chloride solution is slashed accidentally on the eye, it can damage the eyes. If it comes repeatedly into contact with skin or inhaled, it can result in ulcerations of the skin and occupational asthma.


    • Storage

    Zinc chloride can be stored in properly closed containers under cold to warm environment, in a temperature range of 2 to 40 degree Celcius. Damaged containers can be dangerous. Containers of zinc chloride can be dangerous even when empty because residues will remain as particles in the form of solids or dust.
