Description

The petrol fraction is subdivided into several subgroups, so-called special petrols. Petrol benzene boils between 40 °C and 70 °C, for example, and regular petrol boils between 65 °C and 90 °C. In experiment C2.3.3.1, a boiling point analysis is carried out on petrol. For this purpose, different petrol fractions are heated in a distillation apparatus in order to determine the boiling range.
