ABSTRACT:
An apparatus is provided for synthesis and collection of higher order chemical compounds from lower order precursors. The apparatus includes a first silent electric discharge reactor configured to synthesize an intermediate product (e.g., disilane) from a precursor chemical (e.g., monosilane). A second silent electric discharge reactor is connected downstream of the first reactor. This second reactor is configured to convert the intermediate product into the higher order chemical compound (e.g., trisilane). Multiple condensation traps are also connected to receive effluent from the second reactor, which will generally include the compound of interest as well as unreacted precursor and intermediate product. In the illustrated embodiment, a parallel second condensation traps is also included to shunt flow and continue collection while the chemical of interest is removed for purification. Moreover, parallel second condensation traps for the intermediate product and unreacted (or recombined) precursor allow continued collection while the contents of the first traps are recycled in the reactor(s).
