Description
Этилендйамин и полиэтиленполиамины получают из дихлорэтана и аммиака (или аммиачной воды) в аппаратуре периодического дейстстви (автоклавах). Недостаток автоклавного периодического способа в его малой производительности.Ethylene diamine and polyethylene polyamines are obtained from dichloroethane and ammonia (or ammonia water) in a periodical apparatus (autoclave). The lack of autoclave periodic method in its low productivity.
Насто щим изобретением предлагаетс непрерывный способ получени этилендиамина и полиэтиленполиаминов в аппарате специальной конструкции. Способ заключаетс в том, что дихлорэтан и аммиачна пода подогреваютс до температуры реакции и непрерывно подаютс в смеситель (см. чертеж), имеющий насадку, через распылительные устройства 1 н 2.The present invention provides a continuous process for the preparation of ethylene diamine and polyethylene polyamines in an apparatus of special design. The method consists in heating dichloroethane and ammonia to the reaction temperature and continuously feeding it into the mixer (see drawing), which has a nozzle, through a 1 n 2 spray device.
Аппарат представл ет собою колонну , состо щую из семи и более царг, из которых имеет насадку и служит смесителем.The apparatus is a column consisting of seven or more pillars, of which it has a nozzle and serves as a mixer.
Продукт реакции из смесител поступает вверх, в камеры дозревани , оформленные в виде царг, через сопла 3, вмонтированные в раздел ющие перегородки каждой камеры , вследствие чего реакционнойThe reaction product from the mixer goes up into the ripening chambers, designed in the form of tsar, through nozzles 3, mounted into the dividing walls of each chamber, as a result of which
массе сообщаетс вращательное перемешивание .rotational mixing is reported to the mass.
Из последней камеры дозревани (их может быть семь и более) готовый сырец непрерывно вытекает через дроссельный винт.From the last ripening chamber (there may be seven or more), the finished raw material continuously flows through the throttle screw.
Реакци протекает при температуре 120-150° и давлении 12- 14 атм.The reaction proceeds at a temperature of 120-150 ° and a pressure of 12-14 atm.
Предмет изобретени Subject invention
1.Способ получени этилендиамина и полиэтиленполиаминов взаимодействием дихлорэтана с водными растворами аммиака, отличающийс тем, что, с целью увеличени производительности, взаимодействие дихлорэтана с водными растворами аммиака осуществл етс под давлением 12-14 атм в аппарате непрерывного действи .1. A method of producing ethylene diamine and polyethylene polyamines by the interaction of dichloroethane with aqueous ammonia solutions, characterized in that, in order to increase productivity, the interaction of dichloroethane with aqueous ammonia solutions is carried out under a pressure of 12-14 atm in a continuous apparatus.
2.Устройство дл осуществлени способа по н. 1 в виде вертикального цилиндрического многосекцнонного аппарата, о.тличающеес тем, что, с целью улучщени и ускорени взаимодействи дйхЛорэтана с водными растворами аммиака , в нижней части аппарата устанавливаетс смеситель - реактор с насадкой, в котором смешивание реагирующих веществ производитс за счет их турбулентного противоточного распылени .2. A device for implementing the method according to n. 1 in the form of a vertical cylindrical multi-section apparatus, distinguished by the fact that, in order to improve and accelerate the interaction of dichloroethane with aqueous ammonia solutions, a mixer-reactor with a nozzle is installed in the lower part of the apparatus, in which the mixing of the reactants is produced due to their turbulent countercurrent spraying .
