Reaction Steps

A 2 liter round-bottomed flange flask was charged with 1000 g (0.624 mol) of a solution of 75% polyisobutene succinate (obtained by reacting the polyisobutene Hyvis® 10, Mw c. 1000, with maleic anhydride) in 25% HAN8572, an aromatic solvent available from Exxon Chemicals. This was heated with stirring to 175° C., following which triethylene tetramine (TETA) (79.4 g, 0.543 mol) was added dropwise using a pressure equalising funnel over 35 minutes. The reaction mixture was then heated at 175° C. for a further four hours. The resulting product was filtered through a 12 mm Celite pad whilst still warm, and analysed. The product was found to be 71.8% pure, with a nitrogen content of 2.75% (theoretical 2.85%).
