(54) СПОСОБ ПОЛУЧЕНИЯ НИТРИЛА НИКОТИНОВОЙ КИС /ЮТЫ(54) METHOD FOR OBTAINING NITRILE OF NICOTINE CUE / UTA
пературе. Смесь продуктов реакции, растворенных в воде, вместе с газовым потоком jHepacTBopHBiuHxcH соединений, направл ют ,В систе1 улавливани и вьвдетен целевого продукта составл ет 85%. Содёр жание смолис1ых примесей составл ет 0,028 г на 1 кг нитрила никотиновой кис- лоты.perature. The mixture of the reaction products, dissolved in water, together with the gas stream of jHepacTBopHBiuHxcH compounds, is directed. In the trap system, the spin-off of the desired product is 85%. The content of resinous impurities is 0.028 g per 1 kg of nicotinic nitrile.
Пример 2. Смесь, содержащую 40 г 3-пиколина, 20О л воздуха и 4О г аммиака, пропускают через трубчатую часть jjeaKTOpa при услови х,, аналоги чных тем, что описаны в примере 1. Реакционную смесь так же, как в примере 1 обрабатывают 4ОО г воды. Паро-газовую смесь вместе с раствором реакционной смеси в воде направл ют в систему улавливани и выделени . Выход целевого продукта составл ет,90% (от теоретического). Содержание смолистых соединений не превышает 0,О28 г на 1 кг нитрила никотиновой кислоты.Example 2. A mixture containing 40 g of 3-picoline, 20 O l of air and 4 O g of ammonia is passed through the tubular part of jjea KTOpa under conditions similar to those described in example 1. The reaction mixture is treated in the same way as in example 1 4o g water. The vapor-gas mixture, together with the solution of the reaction mixture in water, is directed to a trapping and recovery system. The yield of the target product is 90% (of theoretical). The content of resinous compounds does not exceed 0, O28 g per 1 kg of nicotinic acid nitrile.
