Popis:	Experimental (x, y, P) measurements of ethanol + hept-1-yne at 55 °C and 75 °C and butyric acid + butyric anhydride at 120 °C and 155 °C were obtained in an isothermal circulating glass still. The vapor pressure of hept-1-yne was measured from 43 °C to 100 °C. Ethanol + hept-1-yne exhibits moderate positive deviations from ideal behavior and a minimum-boiling homogeneous azeotrope at both temperatures. Butyric acid + butyric anhydride exhibits weak positive deviations, and no azeotrope was observed.
