Preparation of Sulfonamide Derivatives of Phenolic Resins

In this paper the phenol formaldehyde resin was sulfonated by using chlorosulfonic acid at oc then the sulfonated phenol formaldehyde was modified to its corresponding sulfonamide using different amines such as 4-amino pyridine,2-amino pyrimdine, benzidine, 2,¯2,5,ˉ5- tetramethyl benzidine and amoxilline. The different derivatives were characterized by FT-IR and UV. spectroscopy, thermo gravimetric analysis was measured , and physical properties were measured and the rate of hydrolysis of sulfonamide for amoxilline derivative was studied, therefore it was concluded that the amoxilline sulfonamide phenol formaldehyde resin could be possibly used as antimicrobial material for hospitals equipments and other applications.
