| 摘要 |
The present invention provides a liquid fuel composition comprising: a) a liquid base fuel suitable for use in an internal combustion engine; and b) one or more poly(hydroxycarboxylic acid) amide salt derivatives having formula (III): [Y-CO[O-A-CO]n-Zr-R+]mpXq- (III) wherein Y is hydrogen or an optionally substituted hydrocarbyl group, A is a divalent optionally substituted hydrocarbyl group, n is from 1 to 100, m is from 1 to 4, q is from 1 to 4 and p is an integer such that pq=m, Z is an optionally substituted divalent bridging group which is attached to the carbonyl group through a nitrogen atom, r is 0 or 1, R+ is an ammonium group and Xq- is an anion. |
