摘要：
New composition comprises a functional fluid in contact with ferrous metal and a corrosion inhibiting amount of at least one compound of formula (I)
or a derivative thereof in which R 1 , R 2 and R 3 are, independently, hydrogen, a C 1 -C 15 straight or branched chain alkyl residue, a C 5 -C 12 cycloalkyl residue, a C 6 -C 15 aryl residue or C 7 -C 12 alkaryl residue, and R 4 and R 5 are, independently, hydrogen, 2-hydroxyethyl or 2-hydroxypropyl with the provisos that a) R 4 and R 5 are not simultaneously hydrogen, b) when R 4 and R 5 are each -CH 2 -CH 2 -OH, R 1 and R 2 are not simultaneously hydrogen and R 3 is not a pentyl residue and c) that polyalkylene phenol or polycarboxylic ester co-additives are absent:
as well as salts thereof. Some of the compounds of formula I are new.
