Abstract

Thep-n-hexyloxybenzoic acid (I)-p-n-heptyloxybenzoic acid (II) system was investigated by thermal and X-ray phase analyses and dielcometry. Solid solutions of three types were found in the low-temperature region of the system, namely, solid solution based on I (up to 15 mol % II); solid solution based on a compound with the equimolar ratio of the components (γ); and solid solution based on II (>15 mol % II). The range of the two-phase equilibrium (N + I) was 2°–4°; a continuous nematic solution (N) formed in the system. The temperature and composition dependences of dielectric anisotropy Δɛ were characterized. The γ compound showed negative dielectric anisotropy, Δɛ = −1.4, which was constant over the whole temperature range of the nematic phase.
