Abstract
Abstract Israeli shale oil was separated into different components, and their composition was studied by means of IR, NMR, and GLC-MS. The yield of the components extracted from the 210-320°C fraction of the oil was: components soluble in water 0.59, organic acids 0.32, phenols 8.5, and pyridine bases 3.5 wt. %. The phenols content in the total shale oil was found to be 5.4%, that of pyridine bases 3.2%. More than 20 individual compounds were identified in the products of separation, including phenol, methyl phenols, dimethyl phenols, methyl-ethyl phenols, and methyl naphtalenols, 4-propyl pyridine, 2,3,5-trimethyI pyrrol, 2-, and 3-ethyl-3,5-dimelhyi pyrroles, 2-ethyl-4,6-dimethyl pyridine, dimethyl indoles, dimethyl quinolines, uimethyl indoles. Aldehydes, alcohols, ethers Ar-O-R and R-O-R, and esters Ar-COO-R and R-COO-R are not present in the shale oil. NMR spectroscopy resulted in establishing the quantitative distribution of the oil fraction compounds among the principal structures.
