“…Anhydrous acetic acid was obtained by the process described by Bruckenstein (24). Monochloroacetic acid was purified by simple fractional distillation (bp 182.5~ Dichloroacetic acid was distilled under reduced pressure, and the fraction boiling at 102"/20 mm was collected (bp 193 ~ • 1~ Trichloroacetic acid was recrystallized from hot benzene and dried under reduced pressure.…”

Paul and Sreenathan reported abnormally high values of limiting equivalent conductances for several protonic and Lewis acids in DMF and suggested a proton‐jump mechanism (similar to that which is known to exist in water) to explain these data. However, it has been found that these abnormally high values are grossly in error. The error, apparently is made by a uniformly constant factor and seems to have manifested itself in one set of their measurements; it cannot be attributed to be due to a difference in the extrapolation of Anormalvs.c plots. A careful repetition of their work has revealed values which support the earlier work of Thomas and Rochow and Sears et al., and excludes abnormal proton conductance in DMF. The conductance data have been treated with Shedlovsky's equation and the values of K have been calculated from the slopes of the plots of 1/normalΔs normalvs.CnormalΔnormalsf±2 .

“…The extension of the spectrophotometric titration technique to nonaqueous systems was done for a series of phenol derivatives titrated in butylamine (89). An unusual application of this technique involves the determination of water in acetic acid using excess acetic anhydride (16). Ionization constants and spectra of the hydrolysis products of melamine and their ions were presented (63).…”
