Adducts used as additives for lubricants and fuels

摘要

Adducts consists of (a) an epoxide of formula (I) (where, R1 = polypropylene residue having a number average molecular wt. of 150-5000 g/molecular; R2 and R3 = H or CH3, where R2 and R3 are not H and CH3 at the same time); and (b) an amine of formula (II) (where W = H or Z; Z = H or alkylene imine of formula (III), Alk = alkylene; R4 and R5 = H, (cyclo)alkyl, hydroxyalkyl, aminoalkyl, alkenyl, alkinyl, aryl, arylalkyl, or heteroaryl, or together with the N atom form a heterocyclic ring; Alk, R4 and/or R5 can be substituted by alkyl residues carrying hydroxy or amino groups, m = 0-10). Also claimed are (a) the production of the adducts; (b) a fuel composition containing the adducts in 20-5000 mg/kg fuel; and (c) an additive mixture for fuels and lubricants containing the adducts, optionally in combination with usual additive components.
