Diphenyldiethoxysilane

Colorless or yellowish transparent liquid

Diphenyldiethoxysilane is a new diethoxydiphenylsilane based solid-phase microextraction fiber was developed to extract trace levels of polycyclic aromatic hydrocarbons in millk, human urine. Diethoxydiphenylsilane based coating can be used to detect explosives (2,4,5-trinitrotoulene, 2,4-dinitrotoluene, 2,4-dinitrotoluence) and explosive taggants (ethylene glycol dinitrate).This alkylsilylation reagent may be used for surface modification of nanoporous rice husk silica (RHS).

Reagent for preparation of diphenylsilylene derivatives of diols by exchange.
A hybrid organic-inorganic material was prepared from the hydrolytic co-condensation of 3-trimethoxysilylpropylmethacrylate (MAPTMS) and diphenyldiethoxysilane (DPHDES). The synthesis was performed in three steps: (1) MAPTMS pre-hydrolysis, (2) addition of DPHDES, and (3) further hydrolysis of the obtained mixture.
In acid-catalyzed tetraorthosilicate(TEOS) sol–gel process, dimethyldiethoxysilane (DDS) and diphenyldiethoxysilane (DPDS) were added to obtain TDP spherical particles which, according to scanning electron microscopy (SEM) and thermogravimetric (TG) analysis, showed smooth surface and good thermal stability.
