Claims (3)

1. Способ выделения изобутилового и н-бутилового спиртов из спиртоэфирных фракций производства бутиловых спиртов оксосинтеза ректификацией при пониженном давлении с разделяющим агентом, отличающийся тем, что в качестве разделяющего агента используют воду и ректификацию проводят при разности температур между средним сечением укрепляющей части колонны и верхом колонны, равной 5-30°С, и разности температур между низом колонны и средним сечением отгонной части, равной 3-25°С.1. The method of separation of isobutyl and n-butyl alcohols from alcohol-ether fractions of the production of butyl alcohols of oxosynthesis by distillation under reduced pressure with a separating agent, characterized in that water is used as a separating agent and distillation is carried out at a temperature difference between the middle section of the strengthening part of the column and the top of the column equal to 5-30 ° C, and the temperature difference between the bottom of the column and the average cross section of the distant part, equal to 3-25 ° C. 2. Способ по п.1, отличающийся тем, что ректификацию проводят при остаточном давлении в низу колонны 220-700 мм рт. ст.2. The method according to claim 1, characterized in that the distillation is carried out at a residual pressure in the bottom of the column 220-700 mm RT. Art. 3. Способ по пп.1 и 2, отличающийся тем, что ректификацию проводят при массовом соотношении разделяющий агент: бутиловые эфиры, равном (1-20):1 соответственно.3.
