Methanol/Water Mixtures Make Great Cooling Baths
Dry ice baths above −77 °C. In order to maintain temperatures above −77 °C, a solvent with a freezing point above −77 °C must be used. When dry ice is added to acetonitrile, the bath will begin cooling. Once the temperature reaches −41 °C, the acetonitrile will freeze. See more A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect … See more Mixing solvents creates cooling baths with variable freezing points. Temperatures between approximately −78 °C and −17 °C can be maintained by placing coolant into a mixture of ethylene glycol and ethanol, while mixtures of methanol and water span the −128 °C to 0 °C … See more • Jonathan M.
