  • Patent number: 7713435
    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+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.

  • Publication number: 20090250659
    Abstract: An new class of oil-soluble, sulfur scavengers or converts are disclosed where the scavengers include substantially monomeric aldehyde-amine adducts from the reaction of at least one sterically hindered primary or secondary amine and a molar excess of at least one aldehyde. Methods are also disclosed for reducing, reducing below a given level or eliminating noxious sulfur species from fluids using the inventive scavengers and for making the inventive scavengers.
