Preparation method of 3-amino-4-chloroacetanilide_Kain Industrial Additive

background and overview[1] catalytic hydrogenation of aromatic nitro compounds is an industrially important reaction, e.g. used in the preparation of intermediates for agricultural chemicals, dyes and optical brighteners. to prepare stilbene optical brighteners, for example, 4,4′-dinitrostilbene-2,2′-disulfonic acid must be reduced to 4,4′-diamino-stilbene-2, 2′-disulfonic acid, by classical reduction methods or by catalytic hydrogenation. 3-amino-4-chloroacetanilide can be…
