Sodium polysulfide Chemical Properties,Uses,Production
Chemical Properties
Sodium polysulphides have the general formula Na2Sx where x can be 2-6. All of these compounds have been prepared in the solid state, in which they are well defined.
Chemical Properties
Yellow-brown, granular, free-flowing polymer.Combustible.
Uses
The sodium polysulphide solutions used for the preparation of polysulphide elastomers generally have a rank of appro'ximately 2; for elastomers with a high sulphur content which have especially good solvent resistance, a rank of about 4 is used. In general, the rank of a polymer is close to that of the sodium polysulphide solution from which it is formed.
Uses
Manufacture of sulfur dyes and colors, insec- ticides, oil-resistant synthetic rubber (“Thiokol” [Toray]), petroleum additives, electroplating.
Preparation
Sodium polysulphide solutions are most commonly prepared by treating
sulphur with aqueous sodium hydroxide:
Flammability and Explosibility
Non flammable
