摘要
Direct air-sampling atmospheric-pressure ionisation tandem mass spectrometry and FTIR spectroscopy were used to analyse the products of the OH radical- and Cl atom-initiated reactions of hexamethyldisiloxane, [H-2(18)]hexamethyldisiloxane, tetramethylsilane and trimethylsilylmethanol at room temperature and atmospheric pressure. The data obtained indicate the initial formation of (CH3)(3)SiOSi(CH3)(2)OCHO and (CD3)(3)SiOSi(CD3)(2)OCDO from hexamethyldisiloxane and [H-2(18)]hexamethyldisiloxane, respectively, and (CH3)(3)SIOCHO from both tetramethylsilane and trimethylsilylmethanol.
