This mixture, called an azeotrope, is special because its chemical components act as a single substance during boiling.
The flask, equipped with a modified DeanStark device and under nitrogen atmosphere, is put in an oil bath and the mixture is maintained under reflux for 6 h: the residual hydration water is removed as an azeotrope with toluene through the modified Dean-Stark device.

The compositions include a reduced-GWP azeotrope, DR-11, and two higher capacity candidate blends, DR-4, a blend with GWP slightly less than 300 and a temperature glide of about five Kelvins (K), and DR-5, a blend with GWP slightly less than 500, and having a temperature glide of about one K.
