FIELD: separation of volatile agent mixtures in chemical technology; separation of mixtures of chlorosilanes, hydrides, fluorides and organic products at selection of target product.
SUBSTANCE: proposed method includes fractionated distillation in batch-operated rectifying column provided with center feed reservoir. Column operates in mode of selection of fractions from upper and lower points at separation of concentrate of target product by parallel selection of target and non-target fractions upon attaining preset composition till target product is completely exhausted from starting mixture. Proposed method increases productivity by more than 2 times at maximum extraction of target material. Target product is subjected to cleaning to obtain required purity.
EFFECT: enhanced efficiency.
