Alkylnaphthalene succinimides are synthesised and evaluated as flow improvers, pour point depressants and ashless dispersant additives for fuels and crankcase lubricating oils. The synthesis is based on reacting alkylated naphthalene with maleic anhydride in the presence of the following amines: ethylene diamine, diethylene triamine and tetraethylene pentamine. Chlorinated paraffin wax is used as an alkylating agent for naphthalene. Results showed that magnitude in pour point depression as well as cold filter plugging point depression for the tested fuels are highly related to the molecular weight of alkylnaphthalene succinimides. As ashless dispersant additives, results showed that the magnitude of dispersive power for the tested oils is related to the amine compound used.
