“…Silicon compounds (siloxanes and chlorosilanes) were separated by GC and identified by MS in EI and in CI for silicon rubbers and silicon resins respectively. 181,182 Furthermore, D n characterization was performed by GC-MS when PDMS was submitted to corona discharges. 183 Wacholz et al have also analyzed a mixture of cyclic and linear siloxanes by GC-MS and GC-FTIR.…”

Silicon speciation in environmental, biological and industrial matrices is of considerable importance due to its wide use in many consumer and personal care products and industry. In addition, the entry of silicones in various compartments like wastes, soils, air and water highlights the need to perform exposure studies, toxicological surveys and to measure negative effects. Due to possible contamination and trace level presence of silicon compounds, challenges to determination, identification and quantification are presented. The principal species of concern include siloxanes, silanols, silanediols and silanes. State of the art of analytical methods for total silicon determination and silicon speciation are established. Atomic spectroscopic methods are mainly used to measure total Si at trace concentration levels. On the opposite, hyphenated techniques are performed for Si speciation. Particular attention is paid to chromatographic methods coupled to sensitive and selective detectors (MS, AED and ICP) allowing structural information. Liquid and gas chromatography emerge as the most widespread separation techniques. However, other procedures such as MS, NMR, IR and XRF enable a better knowledge of these species. The potential and limitations of hyphenated techniques are highlighted, particularly concerning sensitivity and selectivity. Furthermore, potential sources of contamination and analytical artifacts in silicon determination are reviewed.

“…16,17 The importance of such types of compounds lies in the fact that they will form stable protective coatings on a metal surface at high pyrolytical decomposition temperatures. [18][19][20] It is agreed that the increase in the number of silicon atoms per molecule of organo-multi-silicon compounds will improve the properties of adhesion, coating stability transparency, etc. 21,22 The existence of hydrogen bonding and/or hydroxyl group may exhibit some sort of interaction with different interphases, thus improving adhesion and strength properties.…”

The combination of ultrasonic vibratory beam and gas chromatography-mass spectrometry techniques was used to produce monomers of new organo-multi-silicon coating materials. The reactants of these materials were exposed to high passive conditions through all the experimental phase. By the aid of a capillary column, RTX-5MS, and an EI detector of the Finnigan-Mat GC, a sample was analyzed on the basis of the rules of the predominant M-1(s) ions of the main chromatographic pattern. Fragmentation analysis of the high resolution mass spectrometry patterns led to detection of three new compound structures, designated A, B, and C isomers. These isomers were identified by the differences between their retention times. The mechanistic root for each of the three isomers is fully discussed herein by a process of stepped number of cleavages per molecule.

Silicon are a class of materials with unique properties that make them useful in a variety of applications of commercial interest and support a thriving global industry. This article updates a comprehensive survey of the chemistry and technology of silicones last published in Kirk‐Othmer Encyclopedia of Chemical Technology in 1997. The update contains more than 235 references not cited in the previous version and includes literature published through 2001. A new section dealing with fiber finishing applications has been included in the current version. The review provides an excellent primary reference for this interesting area of chemistry and technology.
