摘要

Silanes esters of 2,2,2-fluorodinitroethanol (ROH) have been prepared from chlorosilanes in approx. 90% yields. The non-compressive shock sensitivity of the high density (1.95 g/cc), crystalline orthoester (RO)4 Si was clearly lower than that of RDX, but the calculated detonation velocities proved similar. Substantially higher boiling points at similar densities (approx. 1.6 g/cc) relative to the reference compound FEFO were realized in the liquid esters (RO)3SiCH3 and (RO)2(CH3)SiOSi(CH3)(OR)2. The sensitivity of the thermally stable product esters toward hydrolysis by atmospheric moisture varied greatly. The energy contents Q of a number of silicon-containing structures were calculated.
