|
Purification Methods |
Fractionally distil through a column packed with glass helices with ca 15 theoretical 20 1.3777. plates. It is highly flammable and is an irritant. [Mills & McKenzie J Am Chem Soc 76 2672 1954, Csakvari et al. J Organometal Chem 107 287 1976, Beilstein 4 IV 4018.] |
|
Physical properties |
Hexamethyldisiloxane is a colorless and transparent liquid. It is easily deliquescent, flammable, and has the risk of causing combustion when exposed to high heat, open flame, and strong oxidizing agents. Boiling point 99.5℃. Flash point -1.1℃. Relative density (d2525) 0.7606. refractive index 1.3750. insoluble in water, soluble in many organic solvents. |
|
Definition |
ChEBI: Hexamethyldisiloxane is an organosiloxane consisting of two trimethylsilyl groups covalently bound to a central oxygen. |
|
General Description |
Hexamethyldisiloxane (HMDSO), a linear polydisiloxane, is an organosilicon reagent commonly utilized as a source for plasma enhanced chemical vapor deposition (PE-CVD) of thin films of silicon compounds. It is also employed as a substitute to silane in silicon integrated circuit technology. Its dissociative ionization by electron impact has been studied by Fourier transform mass spectrometry. Synthesis of plasma-polymerized HMDSO thin films by atmospheric pressure glow (APG) discharge has been reported. Crystals of HMDSO at 148K are monoclinic. Addition of HMDSO to P4S10, improves its efficiency as thionating agent. |
