The Syntheses of Compound Derived (4-butyloxy benzoyloxy) benzaldehyd and Study of these Liquid Crystalline Behavior

Suad Abdul Muttalib Mohammed

Preparation series of liquid crystalline Schiff base Butyloxy benzoyloxy) benzaldehyde and - derived from 4 ( -4 various substituted anilines, having the general formula R1 X=I, F R=C1-C4 R2 X=CH3 R=C1-C4 The characterization of the compounds was achieved by different spectroscopic methods, e.g., UV, IR, 1H-NMR and Mass spectroscopy. The reflects the result of the mesomorphic study (by differential scanning calorimetry and polarized optical microscopy ) carried out on the prepared compounds. It has been found that the compounds (R15, R2 ) are enanotiotropic nematogens The nematic range exhibited by these compounds follows the order (R1 >R2 ) The enthalpy and entropy changes for the various transitions are calculated and reported Miscibility experiments were carried out on three ( two - component) systems and their liquid crystalline behaviour was studied by polarized optical microscopy. the phase diagrams of the binary systems are reported which reveal that The binary systems ( R1 + R2 ) formed simple neutectic mixtures and remained enantiotropic nematogens.
