Abstract: cf. C.A. 50, 12515a. Carbonation of beet-sugar juice contg. 15% sucrose was studied at 85°. The elecrokinetic potential (I) was detd. at 20° in solns. partially carbonated, exactly carbonated to the equiv. point, and overcarbonated to satd. Ca(HCO₃)₂ soln. The dependence of I on the degree of carbonation is shown. All carbonated solns. had a pos. I. In 0.002-0.003N Ca(OH)₂ I reached max. +18.6 mv. In satd. Ca(HCO₃)₂ I reached the highest value of pos. I, +20 mv.
