Description
Известны способы очистки гексаметилендиамина в присутствии воды химических добавок.Known methods of cleaning hexamethylenediamine in the presence of water chemical additives.
Предлагаемый способ очистки гексаметилендиамина по сравнению с известными обеспечивает получение продукта высокой чистоты и стабильности- Это достигают тем, что в качестве добавок используют соли координационно-ненасыщенных металлов. Такие соли способны к образованию комплексов с 1,2-диаминами и шиффовыми основани ми, присутствующими в гексаметилендиамине. В качестве солей координационноненасыщенных металлов используют хлориды железа, алюмини , хрома и никел или смеси двух солей.The proposed method of purification of hexamethylenediamine in comparison with the known provides for obtaining a product of high purity and stability. This is achieved by using salts of coordination-unsaturated metals as additives. Such salts are capable of forming complexes with 1,2-diamines and schiff bases present in hexamethylenediamine. Chlorides of iron, aluminum, chromium and nickel or a mixture of two salts are used as salts of coordinatedly unsaturated metals.
Предлагаемый способ может быть осуществлен следующим образом.The proposed method can be carried out as follows.
К 100 г промыщленного гексаметилендиамина - ректификата, содержащего 0,27% циклогександиамина-1,2 и 0,027% N-алкилальдиминного азота и имеющего температуру застывани 40,2°, прибавл ют 10 мл воды, 1,3 г хлорного железа и 0,13 г хлористого никел . При остаточном давлении 40 мм рт. ст. и температуре 47-50° отгон ют воду- Основную фракцию гексаметилендиамина отбираютпри температуре 110 - 112°. Получают 84 г гексаметилендиамина с температурой застывани 40,6°. Очищенный продукт содержит 0,04% циклогександиамина-1,2 и 0,004% N-алкилальдиминного азота. Адитиновокислый гексаметилендиамин , полученный из очищенного таким образом гексаметилендиамина, характеризуетс стабильной окраскойНиже приводитс таблица сравнительных данных очистки гексаметилендиамина с применением различных солей координационно-ненасыщенных металлов.To 100 g of industrial hexamethylenediamine - rectification containing 0.27% cyclohexanediamine-1.2 and 0.027% N-alkylamine nitrogen and having a pour point of 40.2 ° C, add 10 ml of water, 1.3 g of ferric chloride and 0.13 g of nickel chloride. With a residual pressure of 40 mm Hg. Art. and a temperature of 47-50 ° is distilled off; water. The main fraction of hexamethylenediamine is taken at a temperature of 110-112 °. 84 g of hexamethylenediamine are obtained with a pour point of 40.6 °. The purified product contains 0.04% cyclohexanediamine-1,2 and 0.004% N-alkylamine nitrogen. The aditic acid hexamethylenediamine, obtained from the hexamethylenediamine thus purified, is characterized by a stable color. A table of comparative data on the purification of hexamethylenediamine using various salts of coordination unsaturated metals is given below.
