Description
Предметом изобретени . вл етс способ получени (Моноди-и трибутила|ми1нов путем пропускани смеси паров бутилового спирта и аммиака IB различньгх мол рных соотщошен1И1 х, над (катализатором-активировэнной глуховскОй глиной.The subject of the invention. is a method of obtaining (Monodis and tributyl | mi1nov by passing a mixture of butyl alcohol and ammonia IB vapors of different molar rations1-1x x, above (catalyst-activated deaf clay).
Описываемый способ отличаетс от извесиных тем, что в цел х повышени активност1и катализатора в процессе работы его подвергают дополн1ителыной активации путем обработки паракислородной смесью при температуре 250-300° и затем чистым кислородом при температуре 350-400°.The described method differs from the known ones in that, in order to increase the catalyst activity during operation, it is subjected to additional activation by treatment with a para-oxygen mixture at a temperature of 250-300 ° and then with pure oxygen at a temperature of 350-400 °.
Активацию провод т путем кип чени предварительно прокаленной при температуре 350-400° сформованной или измельченной на кусочки тлуховокой глины с 10%-й сол ной К1ИСЛ10ТОЙ С поСле|дующим промыванием , сушкой и повторным прокаливанием при температуре 350-400°.The activation is carried out by boiling previously calcined molded clay, crushed or crushed into pieces with 10% hydrochloric acid, at a temperature of 350-400 ° C, followed by washing, drying, and repeated calcination at a temperature of 350-400 °.
Подобный катализатор в процессе работы подвергают периодически допатнительным акт1Иваци м путем обработки паракислородно-й смесью при температуре 260-300° и затем Ч1исты|м кислородом при температуре 350-400°.In the course of operation, such a catalyst is periodically subjected to additional acts by treating the para-oxygen mixture at a temperature of 260-300 ° and then with oxygen with a temperature of 350-400 ° C.
Продукты реакции коидансируют при охлаж|дении водой, газообразные продукты реакции (бутилен и др.) отмывают от непрореагированшего аммиака водой и собирают в специальную емкость.The reaction products co-oxidate when cooled with water, the gaseous reaction products (butylene, etc.) are washed from unreacted ammonia with water and collected in a special container.
Выходы смеем аминов при пр01ве|де ии процесса в указанных услови х не .ниже 50% от тео ретически возможного.Outputs dare amines at the start of the process under the specified conditions not lower than 50% of the theoretically possible.
Вы(деле1ние ам1инов производ т нейтрализацией коиденсата сол ной кислотой, отгонкой до сухого остатка солей аминов и разложением последних концентр1ирова«ным растворам едкой щелочи.You (division of amylins are made by neutralizing the codensate with hydrochloric acid, distilling the amines to the dry residue and decomposing the latter with concentrated solutions of caustic alkali.
Вьцделенмые амины раздел ют ректификацией.The separated amines are separated by distillation.
Праимушеством описанного способа вл етс то, что состав получаемых аминов -можно намен ть путем регулировани состава смеси исХ01ДНЫХ веществ. Увеличание соаержа Н1и а1М1Миака в исходной смеси приводит к увеличению выхода шо обутиламина и к онижен-ию выхода трибутиламина и наоборот.The advantage of this method is that the composition of the resulting amines can be changed by adjusting the composition of the mixture of EXAMPLE. An increase in cobalt H1i a1M1Miaka in the initial mixture leads to an increase in the yield of shobutilamine and oniene-ju release of tributylamine and vice versa.

Пример:Example:
Над Приготовленным вышеуказанным {Опособом катализатором в течение 7 часов пропускают смесь 60,4 г бупишового спирта и 18,00 г аммиака в мол рных соотношени х 1:1, при этом врем контакта должно быть 24 сек. 1И темперairypa-350°.Above the prepared above {Alternatively catalyst for 7 hours, a mixture of 60.4 g of bupish alcohol and 18.00 g of ammonia is passed in molar ratios of 1: 1, and the contact time should be 24 seconds. 1 And the temperature of the animalpa is 350 °.
Получают 10,91 г монобутила1М1ина, 14,03 г дибутиламина и 3,44 г трлбутиламина. Выход аминов составл ет 54,5% от теоретически возможного , счита на пропущенный над 1катализатором спирт.10.91 g of monobutyl1M1in, 14.03 g of dibutylamine and 3.44 g of trl-butylamine are obtained. The yield of amines is 54.5% of the theoretically possible value, considering the alcohol passed over the catalyst.
Бутилаимины вл ютс хорошими стабилизаторами, предотвраш.ающими поли1мериза11|ию и самоокислание на1сыш;енных соединений. Они моryir быть также иопользованы в качестве исходного сырь дл получени 1 етрабупилтиурамдисульфида.Butylamines are good stabilizers that prevent polymerizam11 | iy and self-oxidation of nasal compounds. They can also be used as a feedstock to produce 1 etrabupylthiuram disulfide.
