Silanes methylchloro

CA 69, 98129w(1968) [Conditioning particulate materials for use in org expls, is described. Solid pulverulent materials (such as RDX, PETN or AN) suitable for suspension in melted org expls (such.as TNT) were treated before dispersion, to make them wet and disperse better, with.= 1 liq or solid org Si compd (such as methylchloro-silane of the general formula R1R3R3R4Si,...

Another example is the catalytic disproportionation of methylchloro-silanes. Based on a thorough kinetic study (313), any mechanism will have to take into account the following facts (a) The rate is a linear function of the A1C13 concentration (b) the reaction is first order in chlorosilanes (c) the rate equations must reduce to equilibrium constants Ku K2, or K3 [Eqs. (99)—(101)] when the change in concentration with time is zero (d) substantially all the aluminum chloride is associated in some manner with the chlorosilanes.

The disproportionation of 1,1,2,2-tetrachlorodimethyldisilane (2) leads to trichloromethylsilane (1) and oligo(methylchloro)silanes catalyzed by Lewis bases (Eq. 1). 

It is clear that the thin film method can be successfully used to probe low wavenumber vibrations of metal-chlorine containing species. This is the first time these vibrations have been observed for this molecule using IR spectroscopy, and to our knowledge, the only other IR example of the observation of MCl vibrations is firom the work of Tripp and Harr for some methylchloro-silanes on silica [7-9]. Spaces does not permit us to discuss results we have obtained following the chemisorption of other reactive chloro species such as VOCI3 and BCI3 [4]. 

Sivitsova et al examined the effect of 31 stationary phases on the relative volatility of silicon tetrachloride and methylchloro-silanes. Chromatography was carried out at 25 C on columns (2.5 metres x 4mm) of firebrick containing 20% of stationary phase.
