摘要

Six binary system with three common Schiff’s bases B1, B2, B3 mixed with two different common components Viz. Trans p-[p′-methoxy cinnamoyloxy)anisole (A1) [Nm 117.5°-141.5°] and p- Butyloxy benzal –p-chloro aniline [B2] [Sm 85° - 91°C] of the binary systems were studied. Initial slop and hence “Group Slope” values and LTT were determined from the phase diagrams plotted for transition temperatures versus mole % of common component [A1 or A2]. Transition temperatures and melting points of pure components and the binary mixtures were observed through hot stage polarizing microscope. Components of binary systems were synthesized by usual established method and their analytical data matches very well with reported earlier. Though values of initial slopes and group slope differs, but group efficiency order and LTT values remains unaltered and matches with order and values reported earlier.
