Thermoanalytical investigation of mixtures containing oxalic acid, sodium hydrogen oxalate and sodium oxalate

Abstract

The ternary system containing H2C2O4 · 2H2O, NaHC2O4 · and Na2C2O4 was investigated. It was ascertained that the termal curves of the mixtures were not the algebraic sums of their component curves. All thermal decomposition stages were interpreted and the means of performing qualitative and quantitative analyses in the system were given. © 1980 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
