Abstract

Abstract A series of monoazo disperse dyestuffs derived from naphthalimide were prepared. 4-Amino-N-methyl (alternatively N-ethyl, N-propyl, N-butyl) derivatives of naphthalimide were utilised as the diazo components and β-naphthol, N, N-diethyl-m-toluidine, and p- aminoacetophenone constituted the coupling components. To this end, acenaphthene was nitrated and then various unit processes such as oxidation, amination, reduction, ...
