Octamethyltrisiloxane Chemical Properties,Usage,Production

Chemical Properties

Octamethyltrisiloxane is clear colourless liquid.

Uses

Octamethyltrisiloxane is a linear silicone oligomer. It is used as an excipient Dimethicones in pharmaceutical and cosmetic applications can provide long lasting lubricant, smooth feel and spreads easily. Studies demonstrate that it is able to maintain the conformational stability of certain adsorbed proteins such as bovine serum albumin (BSA). Used in the methylation of mercury(II) salts.

Application

As a basis for silicone oils or fluids designed to withstand extremes of temp; as a foam suppressant in petroleum lubricating oil.

Definition

ChEBI: Octamethyltrisiloxane is an organosiloxane that is trisiloxane in which all the hydrogens have been replaced by methyl groups.

General Description

Poly(dimethylsiloxane) (PDMS), also known as dimethicone, is an organosilicon compound that is widely used as a siloxane based elastomer. It is a hydrophobic material with attractive physical and chemical properties such as elasticity, optical transparency, tunable surface chemistry, and low electrical conductivity.

Flammability and Explosibility

Flammable

Purification Methods

Distil it twice, the middle fraction from the first distillation is again distilled, and the middle fraction of the second distillation is used. [Patnode & Wilcock J Am Chem Soc 68 358, Wolcock J Am Chem Soc 68 691 1946, Thompson J Chem Soc 1908 1953, Beilstein 4 IV 4115.]
