Zinc chloride Chemische Eigenschaften,Einsatz,Produktion Methoden

  • Beschreibung Zinc chloride is a white deliquescent salt. It forms acidic solutions in water and in polar organic solvents such as ethanol, acetone, and ether. Anhydrous zinc chloride hydrolyzes with moisture to form hydrochloric acid. It also forms complex ions with water, ammonia, and some organic solvents. Zinc chloride reacts with sulphide to minimise release of H2S gas in waste treatment facilities. Zinc chloride 50% solution also serves as a high-quality mercerising agent for cotton. Zinc chloride is incompatible with strong oxidising agents, moisture, cyanides, sulphides, and potassium.
  • Chemische Eigenschaften White, granular, deliquescent crystals or crystalline powder. A 10% solution is acid to litmus. Soluble in water, alcohol, glycerol, and ether.
  • Chemische Eigenschaften Zinc chloride is white/colorless crystalline granules.
  • Chemische Eigenschaften Zinc chloride is a white hexagonal, deliquescent crystals or colorless solution. The fume is a white particulate dispersed in air.
  • Verwenden Used as a dehydrating agent, as a catalyst and in electroplating, wood preservation, textile processing,petroleum refining,medicine and feed additives.
  • Verwenden Zinc chloride is used as a wood preservative and in fireproofing timber. Other uses are as a deodorant in disinfecting fluids; in dental cements; in electroplating; in etching metals and glass; as flux for soldering; as a mordant in printing and dyeing textiles; in making dry batteries; in denaturing alcohols; in vulcanizing rubber; in manufacturing parchment; in making artificial silk; in making activated carbon and cold-water glues; and in refining petroleum. Also, zinc chloride is used as a dehydrating and condensing agent in organic syntheses. In medicine it is used as an astringent and antiseptic.
  • Verwenden Deodorant, disinfecting and embalming material; alone or with phenol and other antiseptics for preserving railway ties; fireproofing lumber; with ammonium chloride as flux for soldering; etching metals; manufacture of parchment paper, artificial silk, dyes, activated carbon, cold-water glues, vulcanized fiber; browning steel, galvanizing iron, copper-plating iron; in magnesia cements; petroleum oil refining; cement for metals and for facing stone; mordant in printing and dyeing textiles; carbonizing woolen goods; producing crepe and crimping fabrics; mercerizing cotton; sizing and weighting fabrics; vulcanizing rubber; solvent for cellulose; preserving anatomical specimens; in microscopy for separating silk, wool, and plant fibers; as dehydrating agent in chemical syntheses. Dentin desensitizer.
  • Definition ChEBI: A compound of zinc and chloride ions in the ratio 1:2. It exists in four crystalline forms, in each of which the Zn2+ ions are trigonal planar coordinated to four chloride ions.
  • synthetische Zinc chloride is prepared by the reaction of zinc oxide or zinc metal with dilute hydrochloric acid, followed by crystallization:
    ZnO + 2HCl → ZnCl2 + H2O
    Zn + 2HCl → ZnCl2 + H2
  • Allgemeine Beschreibung Zinc chloride is a colorless liquid. Zinc chloride is mildly corrosive to metals. Zinc chloride causes burns to eyes, skin and mucous membranes.
  • ERSCHEINUNGSBILD HYGROSKOPISCHER WEISSER FESTSTOFF IN VERSCHIEDENEN FORMEN.
  • Air & Water Reaktionen When dissolved in water, Zinc chloride is a strong acid. [Handling Chemicals Safely 1980. p. 964]
  • CHEMISCHE GEFAHREN Zersetzung beim Erhitzen unter Bildung giftiger Rauche (Chlorwasserstoff und Zinkoxid). Mittelstarke Säure in wässriger Lösung.
  • ARBEITSPLATZGRENZWERTE TLV: (als Rauch) 1 mg/m?(als TWA); 2 mg/m?(als STEL); (ACGIH 2005).
    MAK: (als Rauch) IIb (MAK nicht festgelegt, aber Informationen vorhanden). (DFG 2005).
  • Reaktivität anzeigen Acidic salts, such as ZINC CHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
  • AUFNAHMEWEGE Aufnahme in den Körper durch Inhalation des Aerosols und durch Verschlucken.
  • INHALATIONSGEFAHREN Verdampfung bei 20°C vernachlässigbar; eine gesundheitsschädliche Partikelkonzentration in der Luft kann jedoch beim Dispergieren schnell erreicht werden, vor allem als Pulver.
  • Health Hazard Solid or water solution is astringent and can irritate the eyes. When ingested, can cause intoxication, severe irritation of stomach, nausea, vomiting, and diarrhea.
  • Health Hazard Exposures to zinc chloride cause adverse health effects and poisoning. On contact with the skin, zinc chloride causes skin burns and ulcerations, redness, eyes develop pain and blurred vision, and any splashes from solutions may cause eye damage. It is extremely destructive to the tissues of the mucous membranes and upper respiratory tract. The symptoms of toxicity include, but are not limited to, burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting, and irritation or corrosion to the gastrointestinal tract with abdominal pain. After repeated exposures of zinc chloride through skin contact, occupational workers develop varying degrees of skin problems, such as dermatitis and skin ulcerations. Repeated inhalation of zinc chloride causes occupational asthma among workers

  • Erste Hilfe Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or in haled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

  • läuterung methode The anhydrous material can be sublimed under a stream of dry HCl, followed by heating to 400o in a stream of dry N2. It sublimes at high vacuum. Also purify it by refluxing (50g) in dioxane (400mL) with 5g zinc dust, filtering hot and cooling to precipitate ZnCl2. Crystallise it from dioxane and store it in a desiccator over P2O5. It has also been dried by refluxing in thionyl chloride. [Weberg et al. J Am Chem Soc 108 6242 1986.] Hygroscopic: minimal exposure to the atmosphere is necessary.
