ROBINSON A stabilized heat exchange medium is disclosed including a fluorocarbon, an absorbant and a tribasic phosphite stabilizer. The preferred absorbants are assymetrical furan derivatives containing at least 1 oxygen with a single bond to an adjacent carbon, and is most preferably an alkyl tetrahydrofurfuryl ether. The fluorocarbon contains 1 or 2 carbons, 1 or 2 hydrogens and the remainder chlorine and fluorine.
