A homologous series n-Propyl-o-[p'-n-alkoxy benzoyloxy] benzoates was synthesized and studied with a view to understand and establish the effect of benzoate derivatives on liquid crystal behaviour by n-propyl group. Ten homologues were synthesized. Eight homologues showed liquid crystal behaviour while two homologues viz. methyl and ethyl homologues escape from liquid crystal behaviour. Curves of the phase diagram drawn from transition temperatures of the homologues as determined by hot stagefatcat:kod6xwrm45d6beyyhbgjwvka2q
