Study of activation energy and order of reaction of some liquid crystals

Liquid crystals of the type p-phenylene-di-p-n-alkoxy benzoate have been prepared. Kissinger isothermal decomposition method has been used for determination of activation energy values of liquid crystals. Kissinger's assessment for shape index of DTA peaks is used to find the order of reaction. There is no direct relationship between the carbon atoms in terminal methylene groups and Ea values. Order of reaction value decreases with increase in heating rate upto carbon atoms 10 in the terminal methylene group but beyond this the order increases or decreases.

LIQUID CRYSTALS - 7. SMECTIC-NEMATIC TRANSITION TEMPERATURE AS A FUNCTION OF ALKYL END GROUP LENGTH IN p-PHENYLENE Di-p-n-ALKOXYBENZOATES.

The Sm-N transition temperatures of the C//1-C//1//2 homologs of some p-phenylene di-p-n-alkoxybenzoates were studied. For three homologous series of these esters (unsubstituted, methyl-substituted, and chlorosubstituted on the central phenylene ring), th
