Abstract:
The invention relates to the use of polymers containing an alpha olefin, a vinylester and an ester of an alpha , beta unsaturated carboxylic acid polymerised in the polymer, as additives for fuel oils and lubricants and, in particular, as a cold flow improver in fuel oils. The invention also relates to fuel oils and lubricants added to said polymers, in addition to additive packets containing said type of copolymers.
Abstract:
The invention relates to a mixture from: a) polar oil-soluble nitrogen compounds which are capable of sufficiently dispersing in fuels paraffin crystals that build up under cold conditions, b) oil-soluble acid amides from polyamines with 2 to 1000 nitrogen atoms and C 8 to C 30 fatty acids or fatty acid-analog compounds containing free carboxyl groups, and c) oil-soluble reaction products from a,ß-dicarboxylic acids with 4 to 300 carbon atoms or the derivatives thereof and primary alkyl amines. The mixture according to the invention is suitable as a paraffin dispersant in fuels, especially in fuels having a biodiesel content.

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:
Fuel-water emulsions in which an alkoxylated, preferably an ethoxylated, polyisobutene is used as an emulsifier are described. Stable emulsions, in particular of diesel-water mixtures, which have advantageous properties when used as fuel in internal combustion engines can be prepared in this manner.

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 petrole um products, especially for gasolines and middle distillates.
Abstract:
The use is described of polymers which contain, in copolymerized form, an α-olefin, a vinyl ester and an ester of an α,β-unsaturated carboxylic acid as an additive for fuel oils and lubricants and in particular as a cold flow improver in fuel oils. In addition, the fuel oils and lubricants additized with these polymers; and also additive packages comprising such polymers are described.
