An active interest in ionic liquids has grown over the last years. This relatively new class of solvents appears to be potentially useful as a "greener" alternative to volatile organic compounds. This work was aimed at studying the effect of addition of the ionic liquid 1-butyl-3-methylimidazolium chloride to two systems (acetic acid (1)-formamide (2) and propionic acid (1)-formamide (2)) on formation of a compound in the solid phase. In previous work, the presence of a solid compound with a formula (CH3COOH)2·HCONH2 was investigated in the binary system acetic acid (1)-formamide (2) and a stable solid compound with a different formula CH3CH2COOH·(HCONH2)2 was found in the binary system propionic acid (1)-formamide (2). In both cases the compound formation is attributed to a strong cross-association (O···H···N). Solid-liquid equilibrium of the systems measured in this work was determined from time-temperature warming curves. In both measured ternary systems with a small addition of the ionic liquid 1-butyl-3-methylimidazolium chloride (i.e. the systems acetic acid (1)-formamide (2)-1-butyl-3-methylimidazolium chloride (3) and propionic acid (1)-formamide (2)-1-butyl-3-methylimidazolium chloride (3)) the above mentioned stable solid compounds are formed and the corresponding melting temperature of these compounds decreased. Dissociation parameters were modelled thermodynamically for solid adducts.
