(est)|Readily hydrolyzed with liberation of hydrochloric acid|Organo-functional silanes are noted for their ability to bond organic polymer systems to inorganic substrates /Silane cmpd/|The reaction of organosilanes with halogens and halogen cmpd usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/|Hydroxyl radical reaction rate constant = 4.49X10-13 cu cm/molec sec at 25 °C (est)

Leichtentzündlich. Dämpfe in der Luft. Reagiert kräftig und exotherm mit Wasser. Zu den Produkten der Reaktion gehört Chlorwasserstoff. Die Wärme kann ausreichen, um in der Nähe brennbare Materialien zu entzünden. Trimethylchlorsilan reagiert kräftig mit Wasser, um gasförmiges HCl zu erzeugen. Basierend auf einem Szenario, in dem die Chemikalie in einen Wasserüberschuss (mindestens 5-facher Wasserüberschuss) verschüttet wird, wird die Hälfte der maximalen theoretischen Ausbeute an Chlorwasserstoffgas in 1,3 Minuten erzeugt.
