The effect of temperature on the hydrostatic limit of 4:1 methanol–ethanol under pressure

We have investigated the pressure-induced solidification of 4:1 methanol–ethanol at 50 °C and 100 °C, using the ruby fluorescence technique and an externally heated diamond anvil cell. The hydrostatic limits of this pressure transmitting medium increases at a rate of 1 GPa per 11 °C to reach 17 GPa at 100 °C. This demonstrates that the hydrostatic limits can be considerably increased by modest heating.
