• Uses: Chlorination catalyst, vapor-deposited molyb-denum coatings, component of fire-retardant resins,brazing and soldering flux, intermediate fororganometallic compounds, e.g., molybdenum hex-acarbonyl. Molybdenum pentachloride (MoCl5) is used as a brazing and soldering flux and to make fire-retardant resins. Molybdenum pentachloride MoCl5 is used as a catalyst for several polymerization reactions involving olefins, vinyl monomers, trioxane, ethylene, vinylcyclohexane, cyclopentene, and butadiene.

Technology Process of Molybdenum pentachloride

There total 34 articles about Molybdenum pentachloride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 88.0%

chlorine (7782-50-5) + molybdenum (7439-98-7) → molybdenum(V) chloride (10241-05-1)

Guidance literature:

dry chlorine was passed over finely divided molebdenum at 300°C; sublimation;

Reference yield:

chlorine (7782-50-5) + molybdenum (7439-98-7) → molybdenum(V) chloride (10241-05-1) + molybdenum(IV) chloride (13320-71-3)

Guidance literature:

In neat (no solvent); introduction of Cl2-gas (8-9 Torr/20 min/1.8 l/h) through purified (90min/H2 stream/1000°C) Mo powder (860 - 1160°C);; extraction of MoCl5 (CCl4); extraction MoCl4 (diethylether or water); further extraction (ethanol or water);;

Reference yield:

tetrachloromethane (56-23-5) + molybdenum(IV) oxide → molybdenum(V) chloride (10241-05-1) + molybdenum(IV) chloride (13320-71-3)

Guidance literature:
