POLYESTER VON POLY(OXYALKYLEN)-HYDROXY-AROMATISCHEN AETHER |
摘要 |
<p>Poly(oxyalkylene) hydroxyaromatic ethers having the formula: (* CHEMICAL STRUCTURE *) (I) or a fuel-soluble salt thereof; where n is an integer from 5 to 100; x is an integer from 0 to 10; R1 and R2 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R3 and R4 are each independently hydrogen or lower alkyl having 1 to 6 carbon atoms; R5 is an acyl group of the formula: (* CHEMICAL STRUCTURE *) wherein y is 1, 2 or 3; R6 is a divalent hydrocarbyl radical, when y is 1, a trivalent hydrocarbyl radical, when y is 2, or tetravalent hydrocarbyl radical, when y is 3, said hydrocarbyl radicals having 1 to about 20 carbon atoms; and each Z is independently selected from the group consisting of: (* CHEMICAL STRUCTURE *) where each R7 is independently alkyl having 1 to 30 carbon atoms, phenyl, aralkyl having 7 to 36 carbon atoms or alkaryl having 7 to 36 carbon atoms. The poly(oxyalkylene) hydroxyaromatic ethers of formula I are useful as fuel additives for the prevention and control of engine deposits.</p> |
