Preparation and spectroscopic characterization of some Schiff's bases derived from Sulphanilamide and aromatic aldehydes

Abstract

Sulphanilamide has been condensed with five different aromatic aldehyde by heating
them together (fusion) or with a small quantity of solvent .The condensation products
have been characterized by IR , H’NMR and GC.mass . The spectroscopic data indicate
that the condensation under these condition gives Schiff bases with 1:1
ratio of sulphanilamide : aldehyde . Only salicylaldehyde differ from that where the
condensation take place on poth sides to give sulphanilamide bis salicylaldehyde .
The yield of all product ranging from 71-87%
