Additive for improving the thermal stability of hydrocarbon compositions

摘要

The invention relates to the use of at least one additive in order to increase the thermal stability of a hydrocarbon composition, said additive being the product of the condensation reaction between at least one alkenyl succinic or alkyl succinic anhydride I and a primary amine II. The invention also relates to a composition comprising the aforementioned additive, an anti-oxidant and a metal deactivator and to fuels containing same.
