Ryzhkov, O. G. published the artcileInterrelation of the structure and properties of mono- and dialkylpyrocatechols, Related Products of alcohols-buliding-blocks, the publication is Khimiya Tverdogo Topliva (Leningrad) (1975), 154-9, database is CAplus.
Alkylation of pyrocatechol, by olefins (e.g., propene trimer and diisobutylene) and alcs. (e.g., Me2CHCH2OH, Me2CHCH2CH2OH), catalyzed by cationite KU 2, gave 3- and 4-monoalkyl and 3,5-dialkyl derivatives; product compositions were determined by uv, ir, and thin-layer chromatog. Ionization constants of the monoalkyl derivatives were determined
