He opened (1891) the formation of alpha-sulfonic acid and anthraquinone disulfonic sulfonation in the presence of mercury. Developed (1891) method of preparing the first acid blue anthraquinone dye. Proposed (1899-1914 gg.) Methods of obtaining new anthraquinone sulfonic acid, and the acid vat anthraquinone dyes and methods benzoylation aminoanthraquinone.
