Summary o 1. Titanium tetrachloride can be used for the quantitative separation of asphalthenes from residual oil products, for the concentration of hetero-atomic compounds of lower molecular weight, for the complete separation of nitrogen compounds of basic character and also for fractionation of resin-asphalthene substances. 2. The action of TiCl 4 on residual oil products liberates asphalthenes as well as basic nitrogen compounds. The asphalthene recovery reaches 100%, and basic nitrogen compounds, 90–98%. Hexane is a more satisfactory solvent then benzene in this process. |
