2. Cooling bathIn organic chemistry, a cooling bath 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 organic liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature. The cooling agents used in these baths include dry ice, liquid nitrogen, and water ice.
