용도

Hexamethyldisiloxane is used as a solvent in organic reactions. It finds application as an international standard for 1H NMR spectroscopy for calibrating chemical shift. Further, it is used in liquid bandages to protect skin from irritation. In addition, it is used to measure tissue oxygen tension as a receptor molecule. It is also used to make low-k dielectric materials for the semi-conductor industries by plasma-enhanced chemical vapor deposition(PECVD) method.

참고

Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, acids, bases and oxygen.

참조 문헌

Silylates primary and sec-alcohols and phenols, in the presence of p-TsOH as catalyst. If the substrate contains acid-sensitive groups, PPTS can be used: Tetrahedron Lett., 4261 (1978). See Appendix 4.

In the presence of FeCl3, reacts with benzotrichlorides to give substituted benzoyl chlorides in good yields: J. Chem. Soc., Chem. Commun., 808 (1977).

Reacts with P2O5 to give trimethylsilyl polyphosphate ('PPSE'), a milder and more convenient dehydrating agent then polyphosphoric acid. For examples, and related reagents, see Phosphorus(V)­ oxide, A13348.
