New data on phase diagram and clathrate formation in the system water–isopropyl alcohol
The phase diagram of the binary system isopropyl alcohol–water was investigated by means of differential thermal analysis and powder X-ray diffraction. Two incongruently melting polyhydrates with the compositions close to the molar ratio of isopropanol to water 1:5 were found. The melting point of o...

Zusammenfassung: | The phase diagram of the binary system isopropyl alcohol–water was investigated by means of differential thermal analysis and powder X-ray diffraction. Two incongruently melting polyhydrates with the compositions close to the molar ratio of isopropanol to water 1:5 were found. The melting point of one of the polyhydrates is −49.6 °C, the melting point of the second one is within the range −38.8 to −30.6 °C. Assumptions concerning the structure of each compound were made on the basis of powder X-ray diffraction data. |
