METHOD OF SYNTHESIZING PURE ADDITIVES AND THE IMPROVED COMPOSITIONS THEREBY PRODUCED

摘要

An improved process of synthesizing gasoline soluble polyolefinic amines or polyether amines comprising the steps of reacting polyolefinic halides or polyether halides with amines in a specific sequence of reactions; distilling off non-reactive amines; neutralizing the reaction mixture; recovering amine(s) and water; and separating polyolefinic amines from the solids with simple filtration or centrifuge or decanting. The gasoline soluble products are used in blended fuels to improve intake valve deposit control in automotive engines.
