Description and Uses
Diphenyl dichlorosilane is a colorless liquid. Ithas a sharp, pungent, HCl-like odor. Molecularweight= 253.21; Specific gravity = 1.22 at 25℃; Boilingpoint= 305℃; Autoignition temperature= 633.6℃; Flashpoint= 142℃ (oc). Hazard Identification (based on NFPA704 M Rating System): Health 3, Flammability 1,Reactivity 2 . Reacts with water; insoluble.
Dichlorodiphenylsilane is a silane based surface modifier, and a precursor which can be used in the synthesis of silica based materials. It is used to modify the surface by providing toughness, durability and resistance to shock. It can be used in the synthesis of a host material for the fabrication of blue phosphorescent organic light emitting diodes (OLEDs).
