“…The Cl 3 SiCH 2 CH 2 + fragment appears at m / e 165, 163, and 161; Cl 3 Si + at m / e 137, 135, and 133; and ClSi + at m / e 65 and 63. All of the fragments in this series show relative intensities typical for trichlorosilanes . The presence of the SF 5 group is indicated by fragments at m / e 127 (SF 5 + ), 89 (SF 3 + ), and 51 (SF + ).…”

Two new SF5-terminated perfluoroalkylsilanesSF5(CF2CF2) n CH2CH2SiCl3 (n = 1 and 2)were synthesized by addition of trichlorosilane to the corresponding synthetic SF5-terminated perfluoroalkenes by hydrosilylation. Thin films of these SF5-silanes on clean silicon oxide substrates were characterized by ellipsometry, aqueous contact angle, and X-ray photoelectron spectroscopy (XPS) methods. The shorter SF5-silane film shows a hydrophobic interface with minimal angle dependence in depth-dependent XPS analysis, suggesting a poorly organized film. The longer SF5-silane exhibits a high aqueous static contact angle (106°) and angular-dependent XPS compositional variance consistent with improved film assembly (fewer defects and more vertical chain orientation). Bulk SF5-bearing materials were fabricated by silane hydrolysis, producing SF5-polymers and cross-linked networks bearing the unique SF5 perfluoroalkyl chemistry.

Silicone components are commonly added to paper in order to reduce the sticking on the surface to favor the separation of commodities with fat matrix from the paper wrapping.In this work infrared spectroscopy (in the HATR version) was evaluated for performing the quantitative determination of the silicone components content present on the surface of the aforesaid packages.The proposed method is demonstrated to distinguish papers that are differentiable for a content of at least 0,1 ± 0,2 g/m 2 , furnishing results in rapid and predictable way and not necessitating any preliminary sample preparation.Its application has allowed, for example, to determine the different level of silicone components that could be found in a paper used for oven-cooking of foods or in paperpackages for minicakes found on the market.

“…Haslam and Jeffs (48) illustrated, with chromatograms, the separation and identification of terpenes and related substances in synthetic and commercial samples by gas chromatography. The analysis of silicones by optical methods was investigated (113); a rapid mass spectrometer procedure for determining methyl and phenyl chlorosilanes in mixtures was described by Hirt (48).…”
