Process for the preparation of 1, 5-Diaminonanhthalin and l-amino-5-nitronaphthalene by direct electrochemical amination of nieht-activated, or deactivated aromatic systems of boron-doped diamond anodes. The targeted and selective production of specific isomeric is often difficult in the second aromatic substitution.
The invention discloses a novel method for synthesizing B naphthalene disulfonic acid ammonium milk bile, wherein, lactic acid and 1, 5-naphthalene disulfonic acid are used as original raw materials which are salified after esterification, acylation, and methyl ester reactions; B naphthalene disulfonic acid ammonium milk bile is then directly and continuously synthesized; separation and purification …
