Description
Известен способ получени морфолииа из диэтиленгликол и аммиака в ирисутстви водорода. Процесс ведут в жидкой фазе ири повышеииом даплеиии-30-400 атм - с примеиением катализаторов гидрировани на основе никел .A known method for producing morpholia from diethylene glycol and ammonia in the presence of hydrogen. The process is carried out in the liquid phase and at a high drip of 30-400 atm - with the use of nickel-based hydrogenation catalysts.
С целью увеличени выхода и упрощени техиологического ироцесса предложено морфолип получать из диэтилеигликол и алшиака в газовой фазе при атмосферном давлении или ири давлеипн до 30 атм в интервале температур 150-250 С в присутствии водорода с примеиеппем катализаторов гидрировани , содержащих в своем составе никель, с последующим выделением морфолниа обычным снособом.In order to increase the yield and simplify the technological process, it was proposed to obtain the morfolip from diethyleglycol and alshiak in the gas phase at atmospheric pressure or ir pressure up to 30 atm in the temperature range of 150-250 ° C in the presence of hydrogen with the addition of nickel containing catalytic catalysts; the selection of morpholine in the usual way.
Пример 1. Через контактную кварцевую или из нержавеющей стали трубку, в которую загружено 100 мл нромьп1 ленного никельхромового катализатора, проиускают смесь паров диэтиленглпкол , аммиака и водорода в мол риом соотиошении 1:10:5 ири температуре 200С. Днэтилеигликоль подают с объемпой скоростью 0,15 час в пересчете иа жидкий диэтилеигликоль. Продукты реакции конденсируютс в холодильнике н собираютс в приемиике. Каталнзат кип т т дл удалени аммиака и подвергают фракционной нерегонке .Example 1. A mixture of diethylene glycol vapor, ammonia and hydrogen in a molar ratio of 1: 10: 5 and at a temperature of 200 ° C is passed through a contact quartz or stainless steel tube into which 100 ml of a nromine nickel chromium catalyst is loaded. The ethylene glycol is supplied at a rate of 0.15 hour in terms of liquid diethyl glycol. The reaction products are condensed in a refrigerator and collected in a receiver. The catalnzate is boiled to remove ammonia and subjected to fractional non-distillation.
В результате разделени получают почти чистый морфолин (содержание морфолииа не ниже , т. кии. 126-i27-C). Выход морфолипа составл ет от теоретического, счита на встунивнип в реакцию днэтнлеигликоль .As a result of the separation, almost pure morpholine is obtained (the content of morpholia is not lower, because the cues. 126-i27-C). The yield of the morpholip is from theoretical, considering the addition of glycol to the reaction.
