A process for isolation of A-methylnaphthalene from raw material with enhanced content of saturated hydrocarbons includes primary rectification of raw material with obtaining wide monomethylnaphthalene fraction and precision fractionation of the fraction. Before the precision fractionation of monomethylnaphthalene fraction pyridine bases, phenols, indole is removed therefrom and it is subject to azeotropic rectification with isolation of saturated hydrocarbons using as an azeotropic agent mixture of monoethanolamine and N,N'-dimethylacetamide taken in the ratio 5.7-11.5:1 and adding thereof in the amount of 13-17 % of purified fraction mass.
