Abstract:

The results obtained for the olefin content of gasoline with the ASTM D1319 Standard Test Method show a strong increase with the humidity of the silica gel used, while such an increase is absent for the aromatic hydrocarbon content. These results seem to suggest that the increased experimental reproducibility, compared to the value of the ASTM D1319 Standard Test Method, which is often observed for the olefin content in proficiency tests, may be due to the use of insufficiently dry silica gel.
