Description
Адиподиннтрил примен етс дл изготовлени полиамидного волокна. Адиподинитрил, идуш,ий на изготовление полиамидного волокна , должен обладать высокой степеишо чистоты .Adiponentryl is used to make polyamide fibers. Adiponitrile, ide, for the manufacture of polyamide fiber, must have a high degree of purity.
Способы получени адиподинитрила из адипиновой кислоты и ее производных предусматривают дальнейшую очистку продукта.Methods for making adipodinitrile from adipic acid and its derivatives provide further purification of the product.
Способ получени адиподинитрила из алифатического сырь , заключающийс в гидродимеризации акрилонитрила известен. Получающийс адиподинитрил содержит нар ду с основным продуктом пропионитрил, р, Р-ДИциандиэтиловый эфир, а также не вступивший в реакцию акрилонитрил и воду.The process for the preparation of adiponitrile from an aliphatic raw material, consisting in the hydrodimerization of acrylonitrile, is known. The resulting adipodonitrile contains propionitrile, p, P-D-cyanoethyl ether, as well as unreacted acrylonitrile and water, along with the main product.
Сущность предложенного способа заключаетс в ректификации смеси на трех колоннах , из которых перва работает при атмосферном давлении, втора - при остаточномThe essence of the proposed method lies in the rectification of the mixture in three columns, of which the first one operates at atmospheric pressure, the second - at residual
давлении 400 мм рт. ст. и треть - при остаточном давлении 12 мм рт. ст.pressure 400 mm Hg. Art. and one third - with a residual pressure of 12 mm Hg. Art.
Предлагаема схема предусматривает нар ду с выделением товарногоадиподинптрпла, содержащего не менее целевого продукта , возвращение в электролизер исходного компонента реакции - акрилонитрила.The proposed scheme provides, along with the release of a product-dipole-containing product containing at least the target product, the return of the initial component of the reaction, acrylonitrile, to the electrolyzer.

Предмет изобретени Subject invention
Способ выделени адиподинптрила с применением ректификации смеси, отличающийс тем, что смесь, полученную гидромеризадней акрилонитрила, ректифицируют на трех колоннах, из которых перва работает при атмосферном давлении, втора - при остаточном давлении 400 мм рт. ст. ц треть -при остаточном давлении 12 мм рт. ст.A method of isolating adipodiptintry using rectification of a mixture, characterized in that the mixture obtained from hydromerizadny acrylonitrile is rectified into three columns, of which the first operates at atmospheric pressure, the second at a residual pressure of 400 mm Hg. Art. c third - at a residual pressure of 12 mm Hg. Art.
