Abstract (en)

[origin: EP0491439A1] The invention provides gasoline compositions comprising a major amount of a gasoline suitable for use in spark-ignition engines and a minor amount of an alkali metal salt of a partial ester of an alkyl polyether alcohol of the general formula <CHEM> in which n is an integer from 4 to 25, R represents a C6-C20 alkyl group and each R<1> independently represents a hydrogen atom or a C1-C10 alkyl group, with a succinic acid derivative having as a substituent on at least one of its alpha-carbon atoms an unsubstituted or substituted aliphatic hydrocarbon group having from 15 to 200 carbon atoms which optionally is connected to the other alpha-carbon atom by means of a hydrocarbon moiety having from 1 to 6 carbon atoms, forming a ring structure; concentrates containing such salts of partial esters; and the use of such salts of partial esters as spark aider and anti-valve stick agent in gasoline compositions.
