Description
Известен способ получени грег-бутилового спирта окислением изобутана в жидкой фазе молекул рным кислородом при высоких температуре и давлении. Предложено вести процесс в присутствии катализатора-щелочных добавок при температуре 60-135°С в среде растворител или без пего. Способ позвол ет снизить темиературу процесса, ишенсифицировать и повысить его селективность. Пример 1. Смесь 30 г изобутана, 252 г 1 н. водного растЕюра щелочи, 0,22 г затравки - гидроперекиси грег-бутила окисл ют воздухом в реакторе из легированной стали, снабжеииом патрубками дл ввода изобутапа и сжатого воздуха и обратным холодильником дл конденсации паров пзобутала, при температуре 125°С и давлении 45 ат.и в течение 10 час. Затем продукты сливают в ловушку и изобутан испар ют; после отгонки не вступившего в реакцию изобутапа остаетс водный раствор продукта окислени , содержащий г/;е7-бутиловый спирт, гидроперекись г/7ег-бутила, ацетон и метиловый спирт в соотношении (но весу) соответственно 1 : 0,040 : 0,2 : 0,08. В результате реакции окисл етс 2,5% исходного изобутана, при этом 88% вошедшего в реакцию изобутаиа превращаетс Б г/7ег-бутило.вый спирт. Пример 2. В аппаратуре, описапной в примере 1, окисл ют смесь 30 г изобутапа и 31 г 1 н. водного раствора соды и 0,70 г гидроперекиси г/оег-бутила. После окислени воздухом при 125°С и давлении 60 аг.м в течение 3 час иолучают водный раствор продукгов окислени , содержащий г/ ег-бутиловый спирт, гидроперекись г/;(;-7--бутила, метаиол и ацетон в С(к:)тноп1еи пг (ио весу) 1 ; 0,39 : : 0,07 : 0,32 соответствеино. Конверси изобутана 3.3%, выход т/)вг-изобутилового сннрта 80%. Предмет изобретени 1.Способ получени грег-бутилового спирта окислением нзобхтаиа молекул рным кислородом иод давлеи1 ем не ниже 40 ог.и и повы иенной температуре, отличающийс тем, что, с целью повышени селективности процесса п его интенсификации, процесс ведут при те.мпературе в присутствии катализатора -- щелочных добавок. 2.Способ по п. 1, отличающийс тем, что процесс ведут в среде растворител , например четыреххлористого углерода или трет-б тилового спирта.A known method for producing gregbutyl alcohol by oxidation of isobutane in the liquid phase with molecular oxygen at high temperature and pressure. It has been proposed to conduct the process in the presence of a catalyst — alkaline additives at a temperature of 60–135 ° C with or without solvent. The method allows reducing the tem perature of the process, sensitizing and increasing its selectivity. Example 1. A mixture of 30 g of isobutane, 252 g 1 n. alkaline water solution, 0.22 g of the seed - Greg-butyl hydroperoxides are oxidized with air in an alloy steel reactor, equipped with connections for isobutap and compressed air and a reflux condenser for condensing the pbobutal vapor at a temperature of 125 ° C and a pressure of 45 at. within 10 hours The products are then poured into a trap and the isobutane is evaporated; after the distillation of the unreacted isobutap, an aqueous solution of the oxidation product containing g /; e7-butyl alcohol, hydroperox g / 7g-butyl, acetone and methyl alcohol is present in a ratio (but by weight) of 1: 0.040: 0.2: 0, 08 As a result of the reaction, 2.5% of the starting isobutane is oxidized, while 88% of the isobutenium which is reacted is converted to Bg / 7g-butyl alcohol. Example 2. In the apparatus described in Example 1, a mixture of 30 g of isobutap and 31 g of 1N is oxidized. an aqueous solution of soda and 0,70 g hydroperoxide g / og-butyl. After oxidizing with air at 125 ° C and a pressure of 60 ag.m for 3 hours, an aqueous solution of oxidation products containing g / E-butyl alcohol, hydroperox g /; (; - 7 - butyl, metaiol and acetone in C (k :) tnop1ei pg (oo weight) 1; 0.39:: 0.07: 0.32 correspondingly. Conversion of isobutane 3.3%, output t /) vg-isobutyl alcohol 80%. The subject matter of the invention 1. The method of obtaining greg-butyl alcohol by oxidizing nsobchtaium with molecular oxygen iodine with a pressure not lower than 40 og and an elevated temperature, characterized in that, in order to increase the selectivity of the process of its intensification, the process is carried out at a temperature of the presence of a catalyst - alkaline additives. 2. A method according to claim 1, characterized in that the process is carried out in an environment of a solvent, for example carbon tetrachloride or t-btyl alcohol.
