    摘要: Detergent additive compositions for gasoline-type fuels comprise at least one compound that corresponds to the general formula: in which R1, R2, R3 and R4 each represent a hydrogen atom or a hydrocarbon radical, for example alkyl, with 1 to 30 carbon atoms, whereby at least one of R1, R2, R3, and R4 is a hydrocarbon radical, n is a number from 1 to 20, m and m′ are each a number from 1 to 30, with m+m′ from 4 to 60. They can be added to gasoline-type fuels at a concentration of 20 to 5000 mg/liter.

    摘要: Compositions that comprise at least one compound that corresponds to general formula (I): in which n is a number from 0 to 20; R1, R2, R3 and R4 each represent a hydrogen atom or a hydrocarbon radical, for example alkyl, with 1 to 30 carbon atoms, whereby at least one of R1, R2, R3, and R4 is a hydrocarbon radical; and m is a number from 1 to 30, can be prepared by a process that comprises the reaction of a hydroxymethylated derivative of tetrahydrofuran with ethylene oxide, then with one or more other epoxidized compounds. These compositions can be used as detergent additives for gasoline-type fuels.
