Abstract

Solid and liquid phase diagrams have been constructed for water+triethylamine, or+N, N-dimethylformamide (DMF) or+N, N-dimethlacetamide (DMA). Solid-hydrates form with the empirical formulae N(C2H5)3.3H2O, DMF.3H2O, DMF.2H2O, DMA.3H2O and (DMA)2.3H2O. All are congruently melting except the first which melts incongruently. The solid-hydrate formation is attributed to hydrogen bond. The results are compared with the references.
