Poly (oxyalkylene) hydroxy aromatic ethers and fuel compositions containing same (POLY (oxyalkylene) hydroxyaromatic ethers and fuel compositions containing the same)

摘要

A poly (oxyalkylene) hydroxyaromatic ether of the general formula (I) or a fuel-soluble salt thereof:;Wherein R_OneAnd R₂Are each independently hydrogen, hydroxy, lower alkyl of 1 to 6 carbon atoms, or lower alkoxy of 1 to 6 carbon atoms; R₃And R₄Are each independently hydrogen or lower alkyl of 1 to 6 carbon atoms; R₅Is hydrogen, alkyl having 1 to 30 carbon atoms, phenyl, aralkyl or alkaryl having 7 to 36 carbon atoms,; RTI ID = 0.0 R₆Is alkyl having 1 to 30 carbon atoms, phenyl or aralkyl or alkaryl having 7 to 36 carbon atoms; n is an integer from 5 to 100; x is an integer of 0 to 10;;The poly (oxylene) hydroxyaromatic ether of formula (I) is useful as an additive for preventing and inhibiting engine deposits.
