The process of isolation of individual (C-3-C-8) n-alkanes from close-cut fractions of straight-run gasoline of the Samgori (Georgia) commercial oil on the CaA zeolite was studied. The possibility of obtaining n-pentane, n-hexane, n-heptane, and n-octane with a purity of 98.4-99.7 wt % was shown. It was found that the purity of n-alkanes obtained complies with technical requirements imposed on these hydrocarbons.
