摘要:
Fuels for internal combustion engines or lubricants contain small amounts of polyisobutylaminoalcohols of the formulae Ia and Ib where R is polyisobutyl having a number average molecular weight of 500 to 5,000 and in each of the two formulae one of the radicals X is OH and the other is the group where the radicals R1 may be identical or different and are each hydrogen, alkyl, hydroxyalkyl or aminoalkyl which may be substituted by further hydroxyl- or amino-carrying alkyl radicals, or the two radicals R1 may form a nonaromatic ring.
摘要:
Halogen-free fuel additives based on a long-chain hydrocarbon having a polar terminal group are obtained by reacting a hydroformylated olefin with a polyamine and hydrogenating the reaction product.
