Thermodynamic characteristics of carbonation of crystalline soda

Thermodynamic characteristics of carbonation of crystalline soda. Prusakova, T. I.; Krasheninnikov, S. A. (Mosk. Khim.-Tekhnol. Inst., Moscow, USSR). Deposited Doc., VINITI 3126-75, 8 pp. Avail. VINITI (Russian) 1975. DOCUMENT TYPE: Report CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 78 The heat capacity, enthalpy, free energy, and entropy changes of most probable reactions in carbonation of Na2CO3.10H2O [6132-02-1] at 273-323 K were calcd. The most probable processes are those with formation of NaHCO3 from Na2CO3.10H2O directly or via intermediate products.

Heat-storage material

Heat-storage material.Some chemicals with cas registry numbers like 7647-14-5 and 6132-02-1 are also used. (Matsushita Electric Industrial Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58183783 A2 27 Oct 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09K005-06. APPLICATION: JP 82-66684 20 Apr 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) A heat-storage compn. consists of Na2SO4.10H2O and Na2CO3.10H2O as major components and NaCl and/or KCl. The compn. lowers the m.p. to ~20° and can be used for passive solar heating system. Thus, Na2SO4.10H2O, Na2CO3.10H2O, and NaCl were blended, and borax and a crosslinked acrylic acid polymer were added to prevent resp. supercooling and phase sepn. The compn. gave the desired m.p. .
