Abstract
Abstract In binary systems, consisting of two structually similar components of which one is a liquid crystal, extrapolation of the transition curves should yield values for latent transition temperatures of the non-liquid crystalline substances. The reliability of this method of arriving at the latent transition temperatures has been questioned by some research workers. An attempt has been made under this investigation to arrive at some conclusive evidence in regard to the reliability of the method. Several binary systems with suitable Schiff's bases as one component and the well-known p-azoxyanisole or p-azoxyphenetole as the other liquidcrystal component have been studied from which a fair conclusion in favour of the dependability of the extrapolation method may be drawn. Yet, there cannot be a final word since some of the binary systems under study pose a difficulty in understanding their behaviour although discrcpancies observed have been accounted for in terms of polarity and non-ideality of the mix...
