Description
Выпускаемый промышленностью технический 97,о%-ный уротропин содержит 1,7-2,5% Вотаги и имеет светло-желтый цвет и непри тный запаиХ обусловливаемые наличием различных примесей.Commercially available technical 97, o% urotropin contains 1.7–2.5% of the Woggi, and has a light yellow color and an unpleasant seal caused by the presence of various impurities.
Наличие примесей и свойство слеживатьс в результате значительной влажности ограничивают применение уротропина в р де отраслей промышленности. Известны способы очистк технического уротропина посредство.м комбинированной очистки водой с углем посредством обработки насыаденным йодным раствором аммиака с последующей промывкой ацетоно.м или двукратной перекристаллизацией из спирта.The presence of impurities and the property of caking as a result of significant humidity limit the use of urotropine in a number of industries. Known methods for purification of technical urotropine by means of a combined cleaning with water and coal by treating with saturated iodine solution of ammonia followed by washing with acetone or by double recrystallization from alcohol.
В цел х упроп1ени способа очистки и получени продукта более высокого качества предлагаетс способ, заключающийс в промывке технического уротропина жидким аммиаком под давлением до 17 атм.In order to support the purification process and obtain a higher quality product, a method is proposed, which consists in washing technical hexamine with liquid ammonia under pressure up to 17 atm.
Промытый жидким аммиаком уротропин представл ет собой белый кристаллический порошок без запаха с содержанием влаги менее 0.1%.Liquid hexamine washed with liquid ammonia is an odorless white crystalline powder with a moisture content of less than 0.1%.
Пример. В стекл нную колонку диаметром 24 мм и высотой 900 мм загружают 116,35 г уротропина, после чего заливают в колонку 200 мл жидкого аммиака. Проход через слой уротропина, жидкий аммиак извлекает все примеси, вследствие чего выход ща из колонки в колбу-приемник жидкость имеет желтокоричневый цвет. Врем прохождени жидкого аммиака через слой уротропина 15 мин. Влажность промытого уротропина 0,05%.Example. 116.35 g of hexamine was loaded into a glass column with a diameter of 24 mm and a height of 900 mm, after which 200 ml of liquid ammonia was poured into the column. Passing through the urotropine layer, liquid ammonia removes all impurities, as a result of which the liquid exiting the column into the receiving flask has a yellow brown color. The time of passage of liquid ammonia through a layer of urotropine is 15 minutes. Humidity of washed hexamine 0.05%.
По той же методике проводи.ти промывку 150 г уротропина 150 мл жидкого аммиака.Using the same procedure, wash with 150 g of hexamine 150 ml of liquid ammonia.
Количество промывной жидкости (после испарени из нее аммиака ) составл ет 5-6 мл.The amount of washing liquid (after evaporation of ammonia from it) is 5-6 ml.
Влажность уротропина, очищенного при данном соотношении компонентов , не превышает 0,2%.The moisture content of urotropine, purified at this ratio of components, does not exceed 0.2%.
Применение перепада давлений значительно ускор ет процесс промывки.The use of a pressure differential greatly accelerates the flushing process.
