Synthesis, Thermochromic Properties and Thermal Behavior of some Schiff Bases. Part I. p, p'-Diaminodiphenylmethane-Schiff Bases and Sulphonamide Schiff Base
摘要:
p, p'-Diaminodiphenylmethane-Schiff bases (SB) of general formula (R)-phCH=N-ph-CH2-ph-N=CHph(R), where R is p-NO2, m-NO2, p-OH, o-OH, p-Cl,-H, p-OCH3, and sul-phonamide Schiff bases (SB) of general formula (R)-phCH=N-ph-SO2NH2, where R is p-NO2, m-NO2, p-OH, o-OH, p-Cl,-H, p-OCH3, were synthesized and their structure have been characterized by the melting pointing, 1HNMR, MS, and elemental analysis. They are thermolabile and undergo thermo-chromism and thermal decomposition after melting. The TG. and DSC measurement were recorded in dynamic air and interpreted.
