    Abstract: Fuel composition contains an Otto fuel and a small amount of an Otto fuel additive containing a hydrophobic hydrocarbon residue and a specified polar group. Fuel composition comprises an Otto fuel containing a maximum of 42 vol.% aromatics and a sulfur content of a maximum of 150 wt. ppm, and a small amount of an Otto fuel additive with effective detergency and valve seat antiwear properties. The additive comprises a hydrophobic hydrocarbon residue and a specified polar group selected from: (a) mono- and polyamino groups with up to 6 nitrogen atoms, (b) nitro groups optionally in combination with hydroxyl groups, (c) hydroxyl groups in combination with mono- and polyamino groups, (d) carboxyl groups or their alkali metal or alkaline earth metal salts, (e) sulfonic acid groups or their alkali metal or alkaline earth metal salts, (f) polyoxy 2-4C alkylene groups, (g) carboxylic acid ester groups, (h) groups derived from succinic acid anhydride with hydroxy and/or amino and/or amido and/or imido groups, and (i) groups obtained by Mannich conversion of phenolic hydroxyl groups with aldehydes and mono- and polyamines.

    Abstract: The invention relates to the use of fatty acid salts of alkoxylated oligoamines (I), whereby: A represents alkylene groups having 2 to 8 C atoms; R represents C7 to C23 alkyl groups or monounsaturated or polyunsaturated C7 to C23 alkenyl groups; Z represents C1 to C8 alkylene groupings, C3 to C8 cycloalkylene groupings or C6 to C12 arylene or aryl alkylene groupings; m represents 0 or a whole number ranging from 1 to 5, and the sum of all variables x has a value ranging from 50 % to 300 % of (m+3). Said fatty acid salts of alkoxylated oligoamines are used as lubricity improvers for petroleum products, especially for gasolines and middle distillates.

    Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with formaldehyde, an oligomer or a polymer of formaldehyde and at least one amine which has at least one secondary amino function and no primary amino function, or c) reaction of the reaction product from a) with at least one adduct of at least one amine which has at least one secondary or primary amino function and formaldehyde, an oligomer of formaldehyde, a polymer of formaldehyde or a formaldehyde equivalent, and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.
