Fundamental Research on Iron(III) Chloride-Methanol System as a Chemical Heat Storage Material

Abstract

A fundamental research was carried out on the physicochemical properties of the iron(III) chloride-methanol system and on the feasibility of the system as the chemical heat storage material. It was found that (1) the heat of solution of iron(III) chloride into methanol is 92 k J per mole which is large enough to construct a dilution-concentration type heat recovey system with a low temperature heat source., (2) Solubilities, boiling points and densities of iron(III) chloride-methanol solutions were measured and specific heat was estimated. The temperature increase per one cycle was calculated to be about 20°C for the dilution of the solution from 1/3. 5 mole fraction of iron(IIII) chloride to 1/6 mole fraction under atomospheric pressure. © 1989, The Chemical Society of Japan.
