Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
THE METHOD OF AMMONOLYZING A MONO-ORGANIC SILICON TRI-HALIDE, COMPRISING DISSOLVING SAID ORGANIC SILICON HALIDE IN AN ORGANIC SOLVENT INERT TOWARD SAID ORGANIC SILICON HALIDE, REACTING SAID DISSOLVED ORGANIC SILICON HALIDE WITH AN AMMONOLYZING LIQUID NITROGEN COMPOUND SELECTED FROM THE CLASS CONSISTING OF LIQUID AMMONIA AND LIQUID PRIMARY AMINE WHEREIN THE AMINO GROUP IS THE SOLE FUNCTIONAL GROUP, BY SIMULTANEOUSLY INTRODUCING CONTROLLED STREAMS OF SAID DISSOLVED ORGANIC SILICON HALIDE AND OF AN EXCESS OF SAID LIQUID NITROGEN COMPOUND INTO A REACTION VESSEL AT A TEMPERATURE BELOW ROOM TEMPERATURE AND IN THE ABSENCE OF WATER, AND MAINTAINING THE TEMPERATURE OF THE REACTION BY ADJUSTING THE REACTANT SUPPLY SO AS TO MAINTAIN AN EXCESS OF SAID AMMONOLYZING LIQUID NITROGEN COMPOUND UNTIL SAID REACTION IS SUBSTANTIALLY COMPLETE.
