62. to FEFO -e quite high (80 to 85%). The overall yield starting from VII, however, is 45 to 55s. and the large volumes and lengthy procedures,decrease the utility of this method even furthero Physical Characteristics of FEW FEFO is a colorless liquid, b.p. 120 to 124'C at 0.3 mm Hg,m.p. 14'C. Its density is 1.595 g/cc at 25'C. and its index of refraction n2$ = 1.4398. It is soluble in the lower aliphatic alcohols and esters, and in most chlorinated solvents. It is stable to strong acids, and relatively stable to dilute aqueous alkali. Its sensitivity to impact has given values ranging from 11 cm (5096 point, 2 Kg woight, RDX = 28 cm) to 40 to 50 cm (5& point, 2.5 Kg weight). Toxicity data are scanty but tend to indicate relstively lor toxicity, at least by external exposure to skin or eye. ,&alvais of FEPO Gas chromatography has been employed as the most suitable analytical method for FEFO assay. GC FEFO analyses are conducted with a six ring polyphenyl ether column and a sensitive flame ionization detector. A 2-minute isothermal run at 100°C is followed by a programmed increase of 6°C/minute to 20O0C, and an additional 8 minutes at 2CQ°C. All components are eluted within a 20-minute period. These operating conditions give well-resolved peaks with minimal tailing. Although sample sizes have been varied between 0.2 and 0.8 ~l, 0.2 to 0.3 ul is preferred. Preliminary studies suggested that chromatograph oven temperatures between 180 and 20'C would not cause measurable decomposition of FEFO. Therefore, to enhance volatilization and peak shape, a pre-heater temperature of 185'C was selected. However, at this temperature the area percents of the mor. volatile components did not reproduce well, although consistent data were obtained for the other impurities. A later series of tests of vaporizer temperatures from 150 to 20O'C demonstrated the necessity of operating at 15OoC because of an apparent degradation of FEFO at the higher temperatures. Tho data suggest that the apparent increase in impurities of low retention time at temperatures above 15OCC is actually due to degradation of FEFO. Its assay decreases with the increase of these inpuritiea attendant with the increased temperatures. By operating the vaporizer at 15OoC, reproducible chromatograms are obtained without noticeably altering the elution times. The anhydrous potentiometric titration applicable to FDNE may be used for TEFO also. FEPO can be titrated in acetonitrile with tetrabutylammonium hydroxide to give a single well-defined break corresponding to the removal of four protons per mole. A single sample assayed 08.816 FEFO, compared with 86.d obtained by gas chromatography. Since the impurities in FEFO are also apt to have acidic properties, this method was not developed further.
