Continuous synthesis meets continuous purification to produce pure products from crude reaction mixtures. In the nucleophilic aromatic substitution of 2,4-difluoronitrobenzene with morpholine the desired monosubstituted product can be continuously separated from the byproducts in a purity of over 99 %

2,4-Difluoro-5-nitrobenzenesulfonic acid has been synthesized by the sulfonation of 2,4-difluoronitrobenzene, and precipitated with KCl as the potassium sulfonate. The structure was confirmed by chemical and spectroscopic methods (IR, 1H-NMR, 13C-NMR, 19F-NMR, UV, MS and ultimate organic analysis). Lysozyme was cross-linked
