N2 - The focus of this experimental research was to investigate an alternative to purchasing white fuming nitric acid (WFNA) from a distributor for use as a non-toxic, hypergolic oxidizer in a bipropellant rocket engine due to the rapid decline in availability and spike in cost. WFNA was distilled, titrated, and droplet tested in a laboratory setting while controlling the parameters that affect the quality of the yielded product. Namely, the distillation's nitrate salt reactant, heating mantle temperature, and endpoint temperature were varied to optimize the concentration, percent yield, and ignition delay time with N,N,N',N'tetramethylethylenediamine (TMEDA) fuel of the distilled WFNA. The distilled WFNA was compared to >99.5% pure WFNA purchased from a manufacturer.
