Polymerization is analysed the conditions for hexamethylcyclotrisiloxane

polymerization conditions for hexamethylcyclotrisiloxane is a kind of chemicals, is a kind of determination of ferrous, cadmium and molybdenum reagents, REDOX indicator. White or light red crystalline powder, soluble in alcohol, ether, benzene, trichloromethane and petroleum ether; Dissolved in water, the solution appears red when it meets ferrite. Melting point range: 70-72°C; Moisture: <0.50%; Free chlorine: <0.001%; Sulfate: <0.005%; Heavy metal: <0.005%. Other Name: α,α' -Dipyridyl; English Name: 2, 2-dipyridyl; Alpha and alpha '- Dipyridyl; 2,2'-Bipyridine. Molecular Formula: C10H8N2, Molecular Weight: 156.2, CAS No.366-18-7.

Flammability hazard characteristics:

Combustible; The combustion produces toxic nitrogen oxide fumes.

Storage and transportation characteristics:

Warehouse ventilation and low temperature drying; Store separately from food ingredients.

Extinguishing agent:

Dry powder, foam, sand, carbon dioxide, water mist.

Preparation of polymerization conditions for hexamethylcyclotrisiloxane need to mix with anhydrous ferric chloride anhydrous pyridine, heating reaction, crystallization cooling solidification have red and black. Excess pyridine is removed by steam heating. Steam out α, α '-bipyridine. Add sodium hydroxide and extract with ether, remove ether to obtain crude product. The pure 2,2 '-bipyridine was obtained by decolorization and filtration of iron-free activated carbon.

polymerization conditions for hexamethylcyclotrisiloxane must be used with care, careful to store, so as to avoid unnecessary accident.
