Importance of the Boiling Point of chemical compounds

The Boiling Point is a unique characteristic of a substance. Determining the Boiling Point of an unknown substance can help in identifying a sample by comparing the measured value with reference values. In this application example, the MP80 Melting Point System is used to measure the Boiling Point of Acetone. From the material safety data sheet of Acetone, the Boiling Point is listed as 56.2 °C. The following procedure can be adopted for other substances.

How to determine the Boiling Point of a chemical compound like Acetone?

The Boiling Point (BP) of a substance refers to the temperature at which the liquid substance begins to transform into vapor, once the environmental pressure surrounding the liquid has been reached.

As temperature rises, gas bubbles are formed within the liquid and escape to the surface. These ascending bubbles are detected by the METTLER TOLEDO Melting Point System MP80 and used as a basis for the automatic Boiling Point determination.

Most determinations of the boiling temperature are made at ambient pressure (i.e. laboratory) and a calculation is necessary to derive the normal BP from the measurement. To make BP measurements simple and ensure maximum accuracy, the METTLER TOLEDO Excellence Melting Point System MP80 has two valuable features: the ambient pressure is determined with a built-in calibrated pressure sensor, and the temperature compensation to sea-level pressure (1013.25 hPa) is automatically calculated and applied to the results.

With this application note, you will learn how to determine the Boiling Point of chemical compounds like Acetone using METTLER TOLEDO’S Melting Point System MP80.
