Mordant Dyes Derived From 4-(2-Phenyl-4-Oxo-3-Quinazolinyl)-4'- Amino Diphenyl Sulfone and its Studies as M(II) - Schiff Base Complexes

S. B. Mehta, Raksha V. Zala and P. N. Dave

The aim of this study is to determine the stability constant and dyeing characteristics of some quinazoline metal complexes as M (II) - Schiff base complex systems. The Schiff bases derived from condensation of 4-(2-phenyl-4-oxo-3-quinazolinyl)-4'-aminodiphenyl sulfone with different aldehydes are, 4-(2-phenyl-4-oxo-3-quinazolinyl) -4' (benzylidine)-amino diphenyl sulfone [PBADS]; 4-(2-phenyl- 4-oxo-3"-quinazolinyl)-4'(2-chloro benzylidine)-amino diphenyl sulfone [P-2- CBADS]; 4-(2-phenyl-4- oxo-3-quinazolinyl)-4' (2-hydroxy-l- naphthylmethine)-amino diphenyl sulfone [P-2- HNMADS] and 4- (2-phenyl-4-oxo-3-quinazolinyl)-4'(2- hydroxy benzylidine)-amino diphenyl sulfone [P-2- HBADS].
