DECAMETHYLTETRASILOXANE Usage And Synthesis
Chemical PropertiesColorless or yellowish transparent liquid
UsesA non-cyclic silicone oligomer. Used in the methylation of mercury(II) salts. Study shows that it transformed by a specific microflora and in the natural environment degraded by mechanisms similar to other organic compounds.
UsesDecamethyltetrasiloxane can be used as a basis for silicone oils or fluids designed to withstand extremes of temp; as a foam suppressant in petroleum lubricating oil.
Flammability and ExplosibilityFlammable
