PROCESS FOR THE PREPARATION OF POLYALKENAMINES, SEVERAL NOVEL POLYALKENAMINES AND FUEL, LUBRICANT AND ADDITIVE COMPOSITIONS CONTAINING THEM

摘要

A process for the preparation of polyalkeneamines of the formula where R1, R2, R3 and R4, independently of one another, are each hydrogen or an unsubstituted or substituted, saturated or mono- or polyunsaturated aliphatic radical having a number-average molecular weight of up to 40000, at least one of the radicals R1 to R4 having a number average molecular weight of from 150 to 40000, and R5 and R6, independently of one another, are each hydrogen, alkyl, cycloalkyl, hydroxyalkyl, aminoalkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylarlyl, hetaryl or an alkyleneimine radical of the formula 2223 י" ד באלול התשס" ד - August 31, 2004 where Alk is straight-chain or branched alkylene, m is an integer from 0 to 10, and R7 and R8, independently of one another, are each hydrogen, alkyl, cycloalkyl, hydroxyalkyl, aminoalkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylaryl or hetaryl or, together with the nitrogen atom to which they ar bonded, form a heterocyclic structure, or R5 and R6, together with the nitrogen atom to which they are bonded, form a heterocyclic structure, it being possible for each of the radicals R5, R7 and R8 to be substituted by further alkyl radicals carrying hydroxyl or amino groups, wherein an epoxide of the formula where R1, R2, R3 and R4 have the abovementioned meanings, is reacted with a nitrogen compound of the formula where R5 and R6 have the abovementioned meanings, to give the amino alcohol of the formula the amino alcohol is catalytically dehydrated and the olefin formed is hydrogenated to give the amine of the formula (I). 2224 י" ד באלול התשס" ד - August 31, 2004
