Abstract
An improved process of synthesizing gasoline soluble polyolefinic amines or polyether amines comprising the steps of reacting polyolefinic halides or polyether halides with polyamines in a specific sequence of reactions; distilling off non-reactive polyamine; neutralizing the reaction mixture; recovering polyamine(s) and water; and separating polyolefinic amines from the solids with simple filtration or centrifuge or decanting.
