“…It appears that there are no corresponding data on the effect of HCOOH and CH,COOH addition in the liquid-phase ozonolysis to be compared with the present data. The scant data on the ozonolysis in HCOOH [19,20], and in CH,COOH [21] indicate that the products were highly reactive and decomposed under the experimental conditions. In fact.…”

Ozonolysis of C2H4 was carried out at 295 K in 730 torr synthetic air in the concentration ranges of [O3]0 = 1.9–8.2 ppm and [C2H4]0 = 4.0–15.0 ppm, in the absence and presence of the added HCOOH (1 ppm), CH3COOH (1–10 ppm), and CH3OH (36–100 ppm). In the absence of the added compounds, a nearly complete analysis of the reaction products was achieved, with the yields expressed relative to the converted C2H4: HCHO 0.98, CO 0.26, CO2 0.18, HCOOH 0.05, and the sum of formic acid anhydride (FAN) and hydroperoxymethyl formate (HPMF), CHO(SINGLE BOND)O(SINGLE BOND)CH2OOH, 0.19. In the presence of the added HCOOH, the yield of [FAN + HPMF] increased. The addition of CH3COOH suppressed the formation of FAN and HPMF completely. The addition of large excesses of CH3OH also decreased the yield of [FAN + HPMF] significantly. In both cases, new products with the formula R(SINGLE BOND)O(SINGLE BOND)CH2OOH where R = CH3CO and CH3 for CH3COOH and CH3OH, respectively, were formed. The present results, together with the formation of hydroxymethyl hydroperoxide, HO(SINGLE BOND)CH2OOH, with added water vapor (Horie et al., Geophys. Res. Lett., 21, 1523, (1994)) were explained by the reaction of the Criegee biradical CH2OO with the added hydroxy compounds ROH. Formation of the products with the general formula R(SINGLE BOND)O(SINGLE BOND)CH2OOH indicates that the RO(SINGLE BOND)H bond fission has taken place. © 1996 John Wiley & Sons, Inc.
