چکیده
4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene acrylate (C H N O ) containing an acryloxy ' 19 20 4 4 group, first 4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene was prepared by reacting 4' nitrobenzenediazonium salt with N-ethyl-N-hydroxy ethylaniline and then its acryloxyloxy derivative was synthesized in a Schoten-bauman type reaction. The characterization of the synthesized azo-ester dye has been described by IR, UV-vis, HNMR, CNMR spectroscopic techniques. The structure of the present compound 1 13 has been determined by single-crystal X-ray diffraction. The synthesized azo-ester compound crystallizes in orthorhombic, space group P2 2 2 with Z=4. The thermal behavior of compound has been determined by 1 1 1 Differential Scanning Calorimetry (DSC) technique.
