ABSTRACT:
Carboxylate salts of amines are used as components of heat exchange fluids. The amines may have a ratio of N to C of 1:0 to 1:12 and the carboxylate anion may be derived from an acid of the formula H(CH2)0-3COOH. A preferred monoamine heat exchange fluid utilizes triethanolamine formate. Lower carboxylate salts of diamines and triamines having the formula R2[N[(CH2)mNR]1-2]R where each R is independently selected from moieties of the formula —CnH2n+1and moieties of the formula H[O(CH2)1-4]—, each m is independently a number from 1 to 6, and each n is a number from 1 to 4, are disclosed as compounds.
