For the comparison of hydroperoxides with methyl ethers (equation 2), we find there is enthalpy of formation data only for dimethyl ether, isopropyl methyl ether and t-butyl methyl ether (again ignoring the ethyl and propyl hydroperoxides). The enthalpies of formal reaction 2 for R = Me, i-Pr and f-Bu (two gas phase enthalpies of formation for f-BuOOH) are —53.1, —54.9 and —37.6 or —48.6 kJmoU, respectively, in the gas phase. In the liquid phase, the enthalpies of reaction are —7.4, —35 (from the estimated enthalpy of formation of isopropyl hydroperoxide) and —20.0 kJmoU, respectively. Because the enthalpy of formation deviations from linearity for dimethyl ether and methyl hydroperoxide might not be identical, the reaction enthalpy might not be consistent with those...

After cooling to r.t., the solution is diluted with water and extracted with three portions of ethyl acetate. The combined extract is dried over anhyd Na2S04. filtered and concentrated in vacuo, and the residue is dissolved in diethyl ether. The ethereal solution is treated with excess diazomethane in diethyl ether, and the solution is filtered and concentrated. The residue is purified by preparative TLC and distilled bulb-to-bulb to give a colorless oil yield 233 mg (85%) 100% ee bp 120sC/0.07 Torr [a]D +12.8 (c = 1.2. CHC13).

NH4S0 4 S0"4+NH 4, and unless the first stage be completed, the calculation cannot easily be made. From the conductivity and f.p. measurements of a normal soln., S. Arrhenius calculated for the ternary ionization, (NH4)2S04 2NH 4+SO"4, the value 2 17 for J. H. van t Hoff s factor i but the result is not probable. H. Koppe calculated i=2 00 for the W-soln. from his osmotic measurements. The effect of additions of non-conductors to the soln. was studied by S. Arrhenius.
