Applications of Linear Elution Adsorption Chromatography to the Separation and Analysis of Petroleum Determination of Total Nonaromatic Olefins in Gas Oils LLOYD R. SNYDER Union Research Center, Union Oil Company of Californiu, Brea, Calif.
b Samples boiling in the gas oil range (350' to 1000° F.) may b e rapidly analyzed for total nonaromatic olefins. Linear elution adsorption chromatography with alumina as adsorbent is used to separate a saturate-olefin fraction which is analyzed for olefins by the olefin-iodine complex absorption a t 340 mp. The present method is more accurate than any previously described routine procedure and is unique in its ability to determine trace amounts (
