Cyclotetrasiloxane

Cyclotetrasiloxane, also know as Octamethyl cyclotetrasilazane, octaphenyl silsesquioxane, 무색이다, clear or milky liquid. It's a mixture of four tetrahedral silicon oxide groups joined by sharing two oxygen atoms.

It is flammable and generally odorless. It is a compound obtained by separation and distillation based on the hydrolysis synthesis process of dimethyldichlorosilane. It is soluble in organic solvents and insoluble in water.

It consists of dimethyldichlorosilane added dropwise to water, stratified, acid water released, the oily substance hydrolyzed with sodium hydroxide solution, and then the hydrolysate and potassium hydroxide added the cracking kettle for cracking. 드디어, fractionation is carried out to obtain Cyclotetrasiloxane.

Cyclotetrasiloxane is an essential intermediate in the silicone industry. It is widely used in various fields such as construction, 전자 제품, 직물, automotive, personal care, 음식, machining, 등.

It is used in the industry for ring-opening polymerization of silicone oils, silicone rubbers, and silicone resins of various degrees of polymerization.

It is used as a lubricant and in electronic equipment, automobiles, personal care products, 및 의약품, among other applications. Its main uses include insulation and moisture protection of radio components and the preparation of silicone polymers such as methyl silicone oil. It has some properties in cosmetics, such as antistatic, emollient, and moisturizer.

It is also a surface de-activator for gas chromatography glass capillary columns. It is a volatile silicone lubricant, but it also solubilizes silica particles into silicone rubbers.
