Polydimethylsiloxane is a prevalent siloxane. In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H[OSiH 2] n OH and [OSiH 2] n. [1]
Silane SiH 4, the parent. Binary silicon-hydrogen compounds (which are sometimes called silanes also) includes silane itself but also compounds with Si-Si bonds including disilane and longer chains. Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane is again the parent member. Examples: triethylsilane (HSi(C 2 H 5)
Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, pyrophoric gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid . [ 6 ] Silane is of practical interest as a precursor to elemental silicon .
Silane precursors with more acid-forming groups and fewer methyl groups, such as methyltrichlorosilane, can be used to introduce branches or cross-links in the polymer chain. Under ideal conditions, each molecule of such a compound becomes a branch point. This can be used to produce hard silicone resins. In a similar manner, precursors with ...
In his works, Kipping was noted for using Grignard reagents to make alkylsilanes and arylsilanes and preparing silicone oligomers and polymers for the first time. [2] In 1945, Eugene G. Rochow also made a significant contribution to the field of organosilicon chemistry by first describing the Müller-Rochow process. [6]
Setting aside silane itself, for which is used mainly in the microelectronics industry as a source of Si, hydrosilanes participate in many reactions. Hydrosilanes are mainly used for diverse styles of reduction in both industrial and laboratory-scale reactions. These including deoxygenation, hydrosilylation, and ionic hydrogenation.
[4] [5] The discovery of the structural differences between Kipping's molecules and the ketones means that silicone is no longer the correct term (though it remains in common usage) and that the term siloxane is preferred according to the nomenclature of modern chemistry. [6] James Franklin Hyde (born 11 March 1903) was an American chemist and ...
Trimethoxysilane is an important substance for producing silane coupling agents. It contains both hydrolyzable siloxane bonds as well as an active silicon-hydrogen bond. Thereby it can be utilized in a series of reactions, such as copolymerization, polycondensation, and disproportionation reactions.
