Enthalpies of solution of alkali metal chlorates and perchlorates in anhydrous formamide

Enthalpies of solution of alkali metal chlorates and perchlorates in anhydrous formamide. Privalova, N. M.; Smirnova, L. S.; Vorob'ev, A. F. (Mosk. Gos. Univ., Moscow, USSR). Vestn. Mosk. Univ., Khim., 17(5), 532-6 (Russian) 1976. CODEN: VMUKA5. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) The heats of soln., .DELTA.H, of KClO3 [3811-04-9] and KClO4 [7778-74-7] in noneq. formamide for concn. 0.01-0. 13454-84-7 and 7601-89-0 are cas registry numbers of chemicals which are used as reagents here.02 m were detd. calorimetrically at 298.15%. The values of .DELTA.H of these salts at infinite diln. were calcd. By using literature values for the differences in heats of transfer of alkali metal cations between H2O and formamide (V., 1972), the values of .DELTA.H for NaClO3, RbClO3, NaClO4, LiClO4, RbClO4, and CsClO4 in formamide were also calcd. For all salts, the values of .DELTA.H in formamide are more neg. than those in H2O. .

Effect of electrode and volume current densities on the electrosynthesis of Berthollet's salt

Effect of electrode and volume current densities on the electrosynthesis of Berthollet's salt. Shlyapnikov, V. A.; Flisskii, M. M.; Shkred, V. V. (USSR). Zh. Prikl. Khim. (Leningrad), 50(9), 2007-11 (Russian) 1977. CODEN: ZPKHAB. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 49, 78 The effect was studied of the electrode and vol. c.d. on the selectivity of electrosynthesis of Berthollet's salt [3811-04-9] using Pt-Ti, Ru oxide coated, PbO2 and MnO2 anodes at various temps. (40-100.degree.). The expts. were conducted by both the conversion method of electrosynthesizing KClO3 from NaClO3 and by the direct electrosynthesis of KClO3 directly from KCl solns. In the 1st case, the initial soln. contained: NaCl 230, KCl 50, KClO3 30 and K2CrO4 3 g/L. In the 2nd case, the electrolyte contained KCl 220 and K2CrO4 3 g/L.
