摘要： A coolant mixture including water and at least one of the compounds chosen from 1-methoxy-2-propanol and 1-ethoxy-2-propanol in the proportions of the corresponding azeotrope or in near-azeotropic proportions. Such a mixture can be used as a heat-transfer fluid in a heat-exchange device, which can be incorporated into an aircraft or spacecraft. A method for obtaining a mixture by fractional distillation is also disclosed.

摘要： The present invention relates to a cooling mixture comprising a fluorinated compound and a non-fluorinated compound, wherein the fluorinated compound is a hydrofluoroether and the non-fluorinated compound includes a carbonyl function, which has a flash point no lower than 23° C. and which is characterised by having low relative volatility. The present invention likewise relates to the use of such a mixture as a coolant in a heat-exchange device.
