Description
An extensive program for fundamental research on petroleum was recently made possible by the contribution of the sum of $500,000 by John D. Rockfeller and the Universal Oil Products Company. The fund is administered by the American Petroleum Institute with the cooperation of the Central Petroleum Committee of the National Research Council. Project 20, entitled, Isolation and Investigation of the Nitrogen Compounds Present in Petroleum, was assigned to the Chemical Laboratory of the University of Texas with Dr. J. R. Bailey as Director. The investigation of the nitrogen compounds in petroleum was begun in 1926 and is now in its fourth year. The Union Oil Company of California has rendered indispensable assistance to the prosecution of the research on nitrogen compounds, not only in contributing samples of crude petroleum and various refinery products for the preliminary investigations, but also by the extraction of nitrogen bases from large quantities of petroleum distillates. Without this assistance it would have been impossible to obtain a sufficient supply of nitrogen bases for an extended investigation. Acknowledgement is made to Mr. R. E. Haylett, Technical Assistant of the Union Oil Company, who has displayed great interest in the problem and has given generous cooperation in the matter of obtaining the material for the investigation. This paper deals in general with the isolation and identification of nitrogen bases from California petroleum distillates and more particularly with the isolation and determination of structure of two bases, C₁₁H₁₂N and C₁₆H₂₅N
