glass bottle filled with inert gas in vitro wooden case liner bedding packaging. Acid corrosion resistant product. GB Class 8.1 815140 UN NO. 2508; IMDG Code page 8193, class 8.1. Store in a cool, ventilated, dry warehouse. The container should be handled with light weight to prevent breakage and humidity. Fire, with cement, sand, carbon dioxide to save. Toxicity and protection: can react with water to release white smoke-like toxic and corrosive hydrogen chloride gas. It will be poisoned if it is taken by mistake. Dust and vapors can irritate the skin, eyes, and mucous membranes. Therefore, when the eyes are irritated, they should be rinsed with water. When the skin is in contact, they should be rinsed with water first, then washed thoroughly with soap.
Background | molybdenum pentachloride is an important catalyst in the field of organic chemicals. Such as it is an effective catalyst for the chlorination of aromatic rings and partial or complete chlorination of phthalic acid anhydride; Can be used to catalyze the synthesis of polypentene rubber, its composition, purity, the content and the presence of trace impurities have great influence on the polymerization reaction; It reacts with the compound of (benzene) phenol to obtain (benzene) phenol molybdenum compound, it also reacts with the Grignard reagent to produce bisarsine and bisarsine compounds. |
Use | molybdenum (V) chloride is used as a reagent for haloalkane halogen exchange (e. G., 2-bromopentane). Molybdenum (V) chloride has also been used as a Lewis acid catalyst in a number of carbon-carbon bond formation reactions in synthetic chemistry. used as chlorination catalyst, refractory resin component, preparation of molybdenum hexacarbonyl. catalyst for chlorination as a component of a chlorination catalyst, a refractory resin, for the preparation of molybdenum hexacarbonyl, a metal-organic compound. |
Application | molybdenum pentachloride was also used to achieve vapor deposition of molybdenum. High purity molybdenum obtained by thermal decomposition of molybdenum pentachloride can be deposited on metal and non-metal surfaces to obtain a thin layer of uniformly adhered hard coating, which has corrosion resistance, high temperature resistance and other characteristics. Using dry hydrogen to control the gaseous molybdenum pentachloride can be reduced to produce very fine particles of molybdenum powder, the molybdenum powder has been used to produce solder, Monel alloy, solder. Molybdenum pentachloride is also an important raw material for the preparation of metal organic compounds such as molybdenum hexacarbonyl. Molybdenum hexacarbonyl is widely used in organic synthesis, thin film materials of metal molybdenum and its compounds, coating materials and so on. |
