Density and excess volume of the binary systems of iso-buthylmethacrylate with acetonitryle and benzene have been measured as a function of concentrations at 293 K and
atmospheric pressure by pycnometric method. The values of excessive and partial molar volumes of the components were calculated. The excess volume for the acetonitryle – isobuthylmethacrylate system receives negative values and for
the benzene system – isobuthylmethacrylate – positive values.
Пікнометричним методом визначено концентраційну залежність густини і надлишкового об’єму бінарних систем ізобутилметакрилату з ацетонітрилом та бензеном за температури 293 K та атмосферного тиску. Розраховано значення надлишкового об’єму та парціальних мольних об’ємів компонентів. Для системи ацетонітрил – ізобутилметакрилат надлишковий об’єм приймає від’ємні значення, а для системи бензен – ізобутилметакрилат – додатні значення.
