Abstract The p-n-butyloxybenzyliden-p'-methylanyline – p-n-pentyloxybenzoic acid system is investigated by polarizing thermomicroscopy and polythermal dilatometry methods. System phase diagram was plotted. The analysis of temperature and concentration dependencies of the system volume properties was carried out. It is shown, that p-n-pentyloxybenzoic acid «building» into p-n-butyloxybenzyliden-p'-methylanyline takes place at the acid concentration of 10,00 mol. % at the nematic and isotropic phase areas.
