Molybdenum pentachloride

property: MoC15 appearance, with it’s physical condition and are solid, liquid and gas are black crystal, black and amber amber liquid and steam. Molecular weight is 273.2, melting point is 194 ℃, boiling point is 268 ℃, 25 ℃ when the density is 2.928 g/cm3. Electrical properties: 25 ℃ is an insulator, 216 ℃ for 1.9 x 10-6 Ω, 258 ℃ for 7.5 x 10-6 Ω.

MoC15 is a volatile and volatile crystal, which is highly pure refractory metal halide. It has chemical effect in the gaseous and liquid phase, the medium temperature is volatile, the gas is easy to decompose into metal molybdenum deposit, easy to dissolve in organic solvents, these characteristics are beneficial to its practical application.

USES: used as chloride catalyst, refractory resin composition, six carbonyl molybdenum, was used to prepare metallic organic compounds.

The effect on the environment:

Leakage emergency treatment

Isolated from contaminated areas, restricted access. Recommended emergency personnel wearing self-contained breathing apparatus, wear anti-acid coveralls. Do not touch the spill directly. Small spill: Collect with a clean shovel in a dry, clean, covered container. You can also use a lot of water rinse, diluted water into the waste water system. Large amount of leakage, collection and recycling or disposal after disposal.

Protective measures

Respiratory protection: In the event of possible contact with dust, a self-priming filtered respirator must be worn. If necessary, wear self-contained breathing apparatus.

Eye protection: Wear safety glasses.

Protective clothing: Wear plastic protective clothing.

Hand protection: Wear rubber gloves.

Other: Worksite no smoking, eating and drinking. Work done, shower dressing.

first-aid

Skin contact: Remove contaminated clothing, rinse skin thoroughly with soap and water.

Eye contact: lift the eyelid, rinse with running water or saline. Medical treatment.

Inhalation: quickly from the scene to the fresh air. Keep the airway open. If breathing is difficult, give oxygen. Such as breathing to stop, immediately artificial respiration. Medical treatment.

Ingestion: drink enough warm water, vomiting, medical treatment.

Fire fighting methods: Firefighters must wear full body acid and alkali fire service. Extinguishing agents: carbon dioxide, sand.
