FIELD: chemistry. n SUBSTANCE: invention relates to a method of increasing molar ratio of methyl to phenyl in one or more aromatic compounds in feed stock. The method involves: A) conducting a reaction between an effective amount of one or more aromatic compounds and an effective amount of one or more reagents which methylate aromatic compounds, which include at least either an alkane, cycloalkane, alkane radical or cycloalkane radical, in the presence of a catalyst which contains a zeolite, to obtain a product which is characterised by molar ratio of methyl to phenyl which is at least 0.1 times greater than that of the feed stock. n EFFECT: invention enables to convert benzene to other substituted aromatic compounds while minimising undesirable products and/or secondary reactions. n 16 cl, 1 ex, 1 tbl |
