Synthesis Of Phenol Formaldehyde Resin By Mannich Bases And Study Some Their Applications Industrial And Biologycal

Abstract

In this work, new phenol formaldehyde resin were prepared by Mannich bases functional groups. The work included two parts ; part one syntheses of Mannich bases monomers formed by the condensation reaction of aromatic aldehyde (P-hydroxy benzaldehyde) with primary amines such as (4-amino antipyrene, 2-aminobenzothiazole, sulfamethaxazole, Metoclopromide and trimethoprim) with secondary amine Piperazine have been synthesized. Then part two included synthesis of phenol formaldehyde resin containing Mannich bases by condensation Mannich bases which prepared in part one and formaldehyde and phenol. These phenol formaldehyde resin were characterized through (FT-IR) and(1H-NMR) spectroscopy so study the biological activity of some of the synthesized compounds .
