Heat exchange fluids comprising amine carboxylates

摘要

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 -C_nH_2n+1 and 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.
