1A mechanistic study of the low pressure pyrolysis of linear siloxanes.

Almond MJ1, Becerra R, Bowes SJ, Cannady JP, Ogden JS, Young NA, Walsh R.

Phys Chem Chem Phys. 2009 Oct 28;11(40):9259-67. doi: 10.1039/b910549b. Epub 2009 Aug 17.

Matrix isolation IR spectroscopy has been used to study the vacuum pyrolysis of 1,1,3,3-tetramethyldisiloxane (L1), 1,1,3,3,5,5-hexamethyltrisiloxane (L2) and 3H,5H-octamethyltetrasiloxane (L3) at ca. 1000 K in a flow reactor at low pressures. The hydrocarbons CH3, CH4, C2H2, C2H4, and C2H6 were observed as prominent pyrolysis products in all three systems, and amongst the weaker features are bands arising from the methylsilanes Me2SiH2 (for L1 and L2) and Me3SiH (for L3).
