Abstract: Kraftstoffzusammensetzung enthaltend in einer größeren Menge einen Ottokraftstoff mit einem Schwefelgehalt von maximal 150 Gew.-ppm, sowie in einer kleineren Menge mindestens ein Ottokraftstoffadditiv mit Detergenzwirkung oder mit ventilsitzverschleißhemmender Wirkung, wobei dieses Ottokraftstoffadditiv mindestens einen hydrophoben Kohlenwasserstoffrest mit einem zahlengemittelten Molekulargewicht von 85 bis 20.000 und mindestens eine polare Gruppierung aufweist, wobei die Kraftstoffzusammensetzung außerdem einen Gehalt an wenigstens einem Niedrigalkanol von etwa 5 bis 75 Vol.-% aufweist.

Abstract: Disclosed are polyisobutene amines of general formula R1CH2-NR2R3 in which R1 represents a polyisobutyl radical that is derived from isobutene and up to 20 percent by weight of n-butene and has a number average molecular weight Mn ranging from 600 to 770, and R2 and R3 independently represent hydrogen, a C1-C18 alkyl radical, C2-C18 alkenyl radical, C4-C18 cycloalkyl radical, C1-C18 alkyl aryl radical, hydroxy-C1-C18 alkyl radical, poly(oxyalkyl) radical, polyalkylene polyamine radical, or polyalkylene imine radical, or a heterocyclic ring along with the nitrogen atom to which they are bonded. Said polyisobutene amines are suitable as detergents in gasolines, reduce valve stickiness, and improve compatibility of the detergents with flotation oils and compatibility in fuel compositions containing a mineral fuel percentage and C1-C4 alkanols.

Abstract: The invention relates to the use of certain ethers as activity-enhancers for water-soluble biocides in homopolar hydrocarbons. The invention also relates to the use of at least one water-soluble biocide combined with at least one of said ethers for controlling micro-organisms and/or for reducing or preventing the multiplication of micro-organisms in essentially water-immiscible hydrocarbons. The invention also relates to additive compositions and hydrocarbon compositions comprising such ethers and biocides, and to a method for controlling micro-organisms and/or for reducing or preventing the multiplication of micro-organisms in hydrocarbons, according to which such a biocide and at least such an ether are added to the hydrocarbon.
