| Physical and Chemical Properties | Chemical formula vcl3. Molecular weight 157.30. Purple hexagonal crystals. Deliquescence. The relative density of 3.0018(4 deg C), the melting point of 425 deg C decomposition, heat disproportionation reaction occurs. Soluble in ethanol, acetic acid, ether, benzene, chloroform, toluene and carbon disulfide. Dissolved in water to generate the decomposition of vanadium acid, hydrochloric acid and two chloride vanadium. The hydrated ion of trivalent vanadium is green, and generates hydrated coordination chloride with excess chloride ion, and generates ammonia compound by reaction with liquid ammonia. It reacts with gaseous ammonia to form nitrides, forms corresponding coordination compounds with amines and other organic compounds, and produces characteristic color reactions with certain aromatic hydroxy acids. It can be obtained by thermal decomposition of Vanadium tetrachloride or by the interaction of vanadium trioxide and disulfide chloride. Vanadium chloride can be used to prepare strong reducing agent vanadium dichloride and organic vanadium compounds, catalysts for organic synthesis and reagents for testing opium. |

VANADIUM(III) CHLORIDE - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| hazard characteristics | This product is not flammable. Toxic. Poisoning by ingestion, skin contact, or inhalation. The vapor strongly irritates the skin, eyes, and mucous membranes. It is strongly corrosive to most metals in case of tide. In the case of humid air or water will emit a white irritating smoke. Vanadium trichloride is more toxic than vanadium trioxide. Mouse oral LD5023mg/kg; Rat oral LD50350mg/kg. |
| instructions for storage and transportation | store in a cool, ventilated and dry warehouse. Should be Isolation with alkaline goods, oxidants and cyanide storage and transportation. Light loading and unloading shall be carried out during operation to prevent vessel damage and moisture, and personal safety protection shall be provided. oxygen gas masks and rubber gloves must be worn during leak treatment. If a small amount of material leaks, it can be washed with a large amount of water. After the thick smoke disappears, it is neutralized with sodium carbonate and then washed with water, and the sewage is discharged into the wastewater system. In case of fire, fire personnel must wear full-body protective clothing and use dry sand, dry powder or carbon dioxide to put out the fire. |
| first aid measures | patients who inhale dust or smoke should be separated from the contaminated area to a place with fresh air, placed to rest and kept warm, severe cases should be diagnosed and treated. Eye irritation must be rinsed with running water. Severe cases of eye irritation must be treated. Skin contact must be rinsed with plenty of water and thoroughly washed with soap. The patients should immediately gargle, drink water and magnesium milk, and send them to the hospital for treatment. |
