Experimental research of two-component mixture distillation in molecular evaporator with wiped film has been presented. The dibutyl phtalate-dibutyl sebacate mixture was used in experiments. The influence of distillation temperature, feed rate and rotor speed on distillation rate and separation efficiency was investigated. The experimental results were compared with model calculations. The Knudsen - Langmuir equation for evaporation rate and ideally mixed film of distilled liquid was assumed in this model.
