Rate Constants and Activation Energies for Gas-Phase Reactions of Three Cyclic Volatile Methyl Siloxanes with the Hydroxyl Radical.

International journal of chemical kinetics

Safron A, Strandell M, Kierkegaard A, Macleod M.
PMID: 27708500
Int J Chem Kinet. 2015 Jul;47(7):420-428. doi: 10.1002/kin.20919. Epub 2015 Apr 23.

Reaction with hydroxyl radicals (OH) is the major pathway for removal of cyclic volatile methyl siloxanes (cVMS) from air. We present new measurements of second-order rate constants for reactions of the cVMS octamethylcyclotetrasiloxane (D
