Product Name:1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane
English Name:1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane
CAS No.:17875-55-7
Aliases:3,3-diphenyl-1,1,5,5-tetramethyltrisiloxane
Molecular Formula:C16H24O2Si3
Physical Properties:Colorless to pale yellow transparent liquid with a slight ether-like odor. Insoluble in water, soluble in organic solvents such as toluene, ethanol, and diethyl ether. Relative density approximately 0.98, refractive index approximately 1.50, boiling point approximately 130°C (2.0 kPa), flash point approximately 110°C. Contains active Si-H bonds and readily participates in hydrosilylation reactions.
Uses:Primarily used in organosilicon synthesis as an intermediate for hydrosilylation reactions, introducing phenyl groups and active hydrogen groups. It can be used to prepare modified silicone oils, silicone resins, and phenyl-containing functional silicone materials, as well as a crosslinking agent and surface treatment agent.
