Abstract
The invention relates to polyalkene alcohol polyetheramines of formula R1—(CH2)n—O—A)m—NR2R3, wherein R1 represents a polyalkene radical derived from C2- to C30-alkenes with a number average molecular weight of 300 to 5000, R2 and R3 each mean, independently of each other, hydrogen or organic radicals with a total of 400 carbon atoms. A denotes alkylene groups with 2 to 8 C atoms, m is a number from 1 to 200 and n denotes the number 0 or 1. The inventive polyalkene alcohol polyetheramines are suitable for use as carrier oils, detergents and dispersing agents in fuel and lubricant compositions.
Claims9
A polyalkene alcohol polyetheramine of the formula I
- R1—(CH2)n—(O—A)m—NR2R3 (I)
- where
- R1 is a polybutyl or polyisobutyl radical derived from isobutene and up to 20% by weight of n-butene and having a number average molecular weight of from 300 to 2500,
- R2 and R3 may be identical or different and are hydrogen, aliphatic or aromatic hydrocarbon radicals, primary or secondary, aromatic or aliphatic aminoalkylene radicals or polyaminoalkylene radicals, polyoxyalkylene radicals, heteroaryl or heterocyclyl radicals or, together with the nitrogen atom to which they are bonded, form a ring in which further heteroatoms may be present, the maximum number of carbon atoms in R2 and R3 together being 400,
- A is 1,2-propylene and/or 1,2-butylene,
