| titleOfInvention | Process for preparing 1,5- or mixture of 1,5- and 1,8-cymethoxyanthraquinones |
| abstract | ) 1. METHOD FOR OBTAINING 1.5 OR MILES OF 1,5- AND 1,8-DIMETOXYANTRACHINRNOV by methoxylation of 1,5- or a mixture of 1,5- and 1,8-dinitroanthraquinones with alkaline solution of methanol. At elevated temperature in the presence of an oxidizing agent, about 1 L and h / a Woo, with the fact that, in order to intensify the process, the latter is carried out in the presence of iron or copper compounds, taken in an amount of 1-2% by weight of dinitroanthraquinone. 2. The method according to claim 1, from l and h ay and with the fact that their compounds of iron or copper are their salts or complex compounds whose ligands are: aliphatic or aromatic carboxylic acid, cyanide or acetylacetone. |
