Usage

General Description

Octachlorotrisiloxane is a chemical compound that is primarily used as an intermediate in the production of other chemicals. It belongs to the class of organosilicon compounds and is categorized as a chlorosilane. OCTACHLOROTRISILOXANE consists of three silicon atoms linked together by two oxygen atoms with the remaining silicon bonds filled with chlorine atoms, giving it the chemical formula of Si3O2Cl8. Due to the presence of the chlorine, this chemical exhibits a significant level of reactivity, making it useful in a range of industrial applications. It is important to handle it carefully due to potential hazards associated with its use.

The SiO/PN Isoelectronic Pair, I Perchlorocyclosiloxanes and Perchlorocyclophosphazenes. Vibrational Spectra and X-Ray Structure Analysis of (Cl2SiO)3 and (Cl2SiO)4

Hexachlorocyclotrisiloxane (2) and octachlorocyclotetrasiloxane (4) were prepared by reaction of SiCl4 with O2 at 955 deg C.Their mass spectra are compared with those of the isoelectronic cyclophosphazenes.The vibrational spectra of 2 and 4 are very similar and closely related to that of (PNCl2)3, but clearly different from that of the puckered (PNCl2)4 molecule.The X-ray examination of 2 and 4 reveals planarity of the (SiO)n, n = 3 and 4 ring systems, with d(Si-O) on average 1.619(4) and 1.584(3) Angstroem, respectively.
