    摘要: A novel oil-soluble polyether diamine compound, a concentrate comprising the compound dissolved in a hydrocarbon solvent, and a haze-free, deposit-resistant and ORI-inhibited motor fuel composition comprising the compound is described. Motor fuel compositions comprising the novel polyether diamine compound of the instant invention are haze-free and improve ORI control and carbonaceous deposit inhibition in motor fuels. Motor fuel compositions of the instant invention may optionally comprise a polyolefin polymer/copolymer component having a molecular weight range of about 500-3500.
