    Abstract

    In recent years many investigators (1–4) have employed chromotography either alone or in conjunction with other separation processes in the analysis of petroleum fractions. Chromotography and distillation have been combined in this work in an effort to obtain relatively homogeneous fractions. Specific objectives were as follows: 1. The determination of the extent and type of separation achieved by these processes. 2. The evaluation of high molecular weight mass spectrometry in type analyses. 3. The characterization of the aromatic portion of a raw East Texas distillate lube oil stock and the furfural refined lube oil made from this stock. 4. The determination of aromatic types in seyeral lube oils made by varying degrees of hydrogenation of the raw stock. Many of the lube oil fractions and all of the hydrogenated oils were prepared in large enough quantity for oxidation studies (5). Correlation between composition and oxidation characteristics was studied. Due to the vastly greater importance of the aromatics in oxidation processes, the work so far has centered on that portion which is preferentially adsorbed on silica gel. This paper describes the methods used and the results obtained so far on the composition of an East Texas raw lube oil distillate, the corresponding furfural refined oil, and several hydrogenated compositions made from the raw oil.
