Lubricant compositions, novel glucamine derivatives and complex compounds containing same Abstract of the Disclosure The invention relates to compositions comprising a lubricant or a hydraulic fluid and at least one compound of the general formula Image (I), wherein n' is 2, 3 or 4, X is -S-, -O-, -O-CO- or -CH2-, R1 is C1-C22alkyl, Cs-C6cycloalkyl or phenyl, and R2 is hydrogen, C1-C8- alkyl, C2-C4alkyl which is substituted by an -OH group, or a group of the formula -CH2-CH(OH)-CH2-X-R1, wherein X and R1 have the given meanings, and to novel compounds of the formula indicated above. The glucamine derivatives of formula I are especially suitable for use as antiwear agents and as extreme pressure additives for mineral and synthetic lubricant oils and hydraulic fluids, and also as amphi- polar ligands for imparting lipophilic properties to intrinsically hydrophilic metal salts, metal oxides, metal hydroxides and to protic acids. The complex compounds so obtained of the formula Image wherein M is a cation of valency m or a proton, X is an anion of valency n, Z is a compound of formula I, Y is water or a neutral organic molecule, p is a value from 0 to 2, q is a value from 1 to 8, m is an integer from 1 to 6 and n is an integer from 1 to 4, are also disclosed.
