| titleOfInvention | Gasoline-engine fuels containing polyetheramines or polyetheramine derivatives |
| abstract | Gasoline-engine fuels con-tain small amounts of a polyetheramine and/or a poly-etheramine derivative of the general formula (I) or (II) where R1 is a phenolpolyether or alkylphenolpolyether radical of the general formula (IIIa) or a cyclohexylpolyether or alkylcyclohexylpolyether radical of the general formula (IIIb) R2 and R3 may be identical or different and are each hydrogen, a phenolpolyether or alkylphenolpolyether radi-cal (IIIa), a cyclohexylpolyether or alkylcyclohexylpoly-ether radical (IIIb), an acyl radical of a carboxylic acid of 2 to 24 carbon atoms or a hydroxyalkyl radical of the general formula (IV) or R2 is alkyl of 1 to 20 carbon atoms and R3 is hydrogen, a phenolpolyether or alkylphenolpolyether radical (IIIa), a cyclohexylpolyether or alkylcyclohexylpolyether radical (IIIb), an acyl radical of a carboxylic acid of 2 to 24 carbon atoms or a hydroxyalkyl radical (IV), R4 is a carboxylate radical of a carboxylic acid of 2 to 24 carbon atoms, R5, R6 and R7 may be identical or different and are each hydrogen or a hydrocarbon radical of 1 to 30 carbon atoms, R8 is a polyether chain obtained from an alkene oxide of 2 to 8 carbon atoms or a mixture of such alkene oxides, having from 2 to 100 alkene oxide units in the chain, and R9 is hydrogen or a hydrocarbon radical of 1 to 6 carbon atoms and m is from 0 to 5, the mean molecular weight Mn of the polyetheramines or polyether-amine derivatives (I) or (II), respectively, being from 500 to 8,000 and the polyetheramines, or the polyether-amines on which the polyetheramine derivatives are based, being prepared by amination of phenolpolyethers or alkylphenolpolyethers of the general formula (Va) or of cyclohexylpolyethers or alkylcyclohexylpolyethers of the general formula (Vb) where R5, R6, R7 and R8 have the stated meanings, with ammonia or a primary amine. The novel polyetheramines and their derivatives have an improved valve-cleaning effect. |
