Separation of Acids from Asphalts
A procedure has been devised for the rapid separation of acids from asphalts using a modified soxhlet filled with potassium hydroxide treated silica. Acids from a whole air blown asphalt and from the maltene and asphaltene fractions from thls asphalt were extracted by this procedure and characterized by Infrared spectroscopy.
