Solubility data are reported for capric, lauric, myristic, palmitic, stearic, and arachidic acids in N,N‐dimethylacetamide (DMA) and N,N‐dimethylformamide (DMF). Complete binary freezing‐point diagrams were constructed for the capric, myristic, and stearic acid systems. A solid, incongruently melting 1:1 molecular compound formed in all except the stearic acid‐DMF system. Calculated solubility data for lauric, palmitic, and arachidic acids in both solvents were in good agreement with experimental determinations on selected compositions.
