Description
Кетоновые .масла, получающиес , как малоценный отход, при производстве ацетона , содержат в своем составе кетоны жирного р да, главную часть которых составл ет метнлпропнлкетон. В литературе , указываетс лишь выделение метилпропилкетона из кетонового масла путем многократной фракционировки без воды при изучении состава кетоно1 ого масла (Hermann Suide, Hans Poll. Cham. Zentralbl. 1927, II, 1896J. Проведенна автором-работа показала возможность выделени метилпропилкетона Путем разгонкн кетонового масла, с водой.Ketone oils, resulting as low-value waste in the production of acetone, contain in their composition ketones of the fatty series, the main part of which is methylpropnylketone. In the literature, it is indicated only the release of methyl propyl ketone from ketone oil by repeated fractionation without water in studying the composition of ketone oil (Hermann Suide, Hans Poll. Cham. Zentralbl. 1927, II, 1896J. The work carried out by the author showed the possibility of separating methyl propylene ketone by disperse , with water.
Предлагаемый способ выделени метнлпропилкетона основан на свойстве последнего кипеть с водой при посто нной температуре (около 83°); то же относитс и к метилбутилкетону, кип щему с водой при температуре около 90°. . Кетоновое масло, полученное при разгонке ацетона-сырца, разгон ют в смеси с водой на обычной периодически действующей ректификационной установке дл ацетона и отбирают первичную метилпропйл-, кетоновую фракцню, йачина с погона с водным отслоем, с удельным весом d 15/15The proposed method for the isolation of methyl propyl ketone is based on the property of the latter to boil with water at a constant temperature (about 83 °); the same applies to methyl butyl ketone boiling with water at a temperature of about 90 °. . Ketone oil, obtained by distillation of crude acetone, is distilled in a mixture with water in a conventional periodically operating distillation unit for acetone and primary methylpropyl, ketone fraction, yachin is withdrawn from the shoulder strap with a water separation, with a specific gravity of d 15/15

около 0,850 и при температуре в «верхней части колонны 85°, и конча погоном при температуре в верхней части колонны 90° с удельным весом d 15/15 не выше 0,850 и с водным отслоем, не превышающим 30% общего объема погона. Полученную первичную метилпропнлкетоновую фракцию , содержащую до 70% метилпропилкетона , подвергают повторной разгонке с водой в той же аппаратуре, отбира вторичную метилпропилкетоновую фракцию с удельным весом d 15/15 0,825-0,830 при температуре в верхней части колонны 83°-86°. Вторична метилпропилкетонова фр акци содержит около 90% метилпропилкетона и, как примесь, воду, метилэтилкетон и метилбутилкетон- Дл получени безводного препарата первичную или вторичную метилпропилкетоновую фракцию, в зависимости от желаемого качества конечного препарата, подвергают разгонке без воды, при чем вода отгон етс при температуре , а готовый метилпропилкетон при температуре 98°-104about 0.850 and at a temperature in the “upper part of the column 85 °, and ending with a shoulder strap at a temperature in the upper part of the column 90 ° with a specific gravity of d 15/15 not higher than 0.850 and with a water separation not exceeding 30% of the total volume of the shoulder strap. The obtained primary methylpropyl ketone fraction containing up to 70% methyl propyl ketone is subjected to repeated distillation with water in the same apparatus, selecting the secondary methyl propyl ketone fraction with a specific weight of d 15/15 0.825-0.830 at a temperature in the upper part of the column 83 ° -86 °. The secondary methyl propyl ketone fraction contains about 90% methyl propyl ketone and, as an admixture, water, methyl ethyl ketone and methyl butyl ketone. To obtain an anhydrous preparation, the primary or secondary methyl propyl ketone fraction, depending on the desired quality of the final preparation, is distilled without water, at which the water is distilled off at a temperature , and the finished methylpropyl ketone at a temperature of 98 ° -104
Аналогичным пор дком ведетс производство метилбутилкетона.Similarly, the production of methyl butyl ketone is carried out.
