Description
Известны способы очистки углеводородов и других органических продуктов от примесей аммиака, заключающиес в том, что дл очистки примен ют промывку водой или обработку продуктов твердым хлористым кальцием. Недостатком этих способов вл етс длительность процесса . Так, например, при промывке водой полное удаление аммиака достигаетс только после энергичного встр хивани в течение 10 мин. При этом наблюдаетс выделение аморфного осадка, который преп тствует быстрому расслаиванию.Methods are known for purifying hydrocarbons and other organic products from ammonia impurities, such as washing with water or treating products with solid calcium chloride is used for cleaning. The disadvantage of these methods is the length of the process. For example, when washing with water, complete removal of ammonia is achieved only after vigorous shaking for 10 minutes. In this case, an amorphous precipitate is precipitated, which prevents rapid delamination.
При обработке твердым хлористым кальцием отсутствие аммиака в углеводородном слое устанавливаетс только после непрерывного встр хивани в течение 10-20 мин.When treated with solid calcium chloride, the absence of ammonia in the hydrocarbon layer is established only after continuous shaking for 10-20 minutes.
С целью ускорени процесса предлагаетс способ очистки углеводородов , например изопрена, выделенного из углеводородной смеси хемосорбцией аммиачным раствором, солей меди, от примеси аммиака 5 /о-нъш водным раствором бикарбоната натри при объемном соотношении к углеводородам 1:1.In order to accelerate the process, a method is proposed for purifying hydrocarbons, such as isoprene, separated from the hydrocarbon mixture by chemisorption with an ammonia solution, copper salts, from ammonia 5 / o-ny impurity with an aqueous solution of sodium bicarbonate at a 1: 1 ratio to hydrocarbons.
При этом полное удаление аммиака достигаетс после встр хивани в течение 1 мин., а расслаивание углеводородного и водного слоев наступает практически мгновенно.At the same time, complete removal of ammonia is achieved after shaking for 1 minute, and the separation of the hydrocarbon and water layers occurs almost instantaneously.
Пример 1. В смеситель загружают равные объемы технического изопрена с содержанием 0,2:Vo вес аммиака и 5Vo водного раствора бикарбоната натри и энергично перемешивают в течение 1-2 мин. При этом происходит расслаивание смеси углеводородов, в которых аммиака содержитс 0, вес.Example 1. Equal volumes of technical isoprene with a content of 0.2 are loaded into a mixer: Vo is the weight of ammonia and 5 V of an aqueous solution of sodium bicarbonate and is vigorously stirred for 1-2 minutes. When this occurs, the separation of the mixture of hydrocarbons, in which ammonia contains 0, weight.
Пример 2- В смеситель загружают равные объёмы технического изоамилена (смесь изомеров) с содержанием 0, вес аммиака и 5Vo водного раствора бикарбоната натри и энергично перемешивают в течение 1-2 мин. При этом происходит расслаивание углеводородов, с содержанием 0,0001% вес аммиака.Example 2- Equal volumes of technical isoamylene (mixture of isomers) with a content of 0, weight of ammonia and 5Vo of an aqueous solution of sodium bicarbonate are loaded into the mixer and vigorously stirred for 1-2 minutes. When this occurs, the separation of hydrocarbons, with a content of 0.0001% by weight of ammonia.
