Abstract
The displacement of dodecane from vertical capillaries with a modified surface by water was studied. Dependences of the contact angles with selective wetting on the time of preliminary contact of dodecane with the capillary walls, length of dodecane column, depth of capillary imm ersion into water, and formation technique of the interfacial meniscus (under advancing or receding conditions) were obtained. Calculation o f the hysteresis in theta(12) angles was made for each case, and the e ffect of the capillary surface on the hysteresis pattern and its value was demonstrated.
