Thermal analysis on some aminobenzoic acids derivates using DSC, TG-FTIR, Hot-stage Microscopy were done on individual derivatives and later same analysis when these derivatives are mixed using physical and kneading method. TG-FTIR, which is a technique coupling TGA and FTIR, was undertaken to check evolved gases in heating these compounds.The thermal behaviour in the solid state of various substituted aminobenzoic acids (3- aminobenzoic acid (3-ABA), 4-aminobenzoic acid (4-ABA), 3-aminosalicylic acid (3-ASA), 4- aminosalicylic acid (4-ASA), and 5-aminosalicylic acid (5-ASA), as well as the "p...
