Description
Предложен снособ получени пиперилена, вл ющегос сырьем дл синтеза высокомолекул рных соединений. Снособ заключаетс в том, что бутен-1 обрабатывают формальдегидом , нолученный при этом 4-этилдиоксан-1,3 в смеси с вод ным паром в соотношении 1 : 2-1 : 3 пропускают над катализатором, состо щим из смеси среднего фосфата (70%) и двузамещенного фосфата кальци (30%) при температуре 350-375°С и объемной скорости в 0,5 л/л кат-час. Процент разлол еип за проход составл ет 60-85% на пропущенный этилдиоксан при выходе нииерилена до 90% от теории на разложенный диоксан.A method for preparing piperylene, which is a raw material for the synthesis of high-molecular compounds, is proposed. The method consists in the fact that butene-1 is treated with formaldehyde, but 4-ethyldioxan-1,3 in mixture with steam in a ratio of 1: 2-1: 3 is passed over a catalyst consisting of a mixture of average phosphate (70% ) and disubstituted calcium phosphate (30%) at a temperature of 350-375 ° C and a space velocity of 0.5 l / l cat-hour. The percentage of break per pass is 60-85% for the missed ethyldioxane, with a yield of nairien up to 90% of the theory for decomposed dioxane.
Пример. В барботажную колонну, заиолленную 37% формалином, содержащим 12,5- 15% серной кислоты (в расчете на воду) подаетс бутен-1 в виде газа или жидкости под давлением 10-15 агм. Реакци продолжаетс 2-2,5 час при температуре .Example. In the bubble column, molded with 37% formalin containing 12.5-15% sulfuric acid (calculated as water), butene-1 is supplied as a gas or liquid under a pressure of 10-15 agm. The reaction lasts 2-2.5 hours at a temperature.
Диализ реакциоиной смеси показывает, что формальдегид в этих услови х вступает в реакцию на 80-85%. При этом основным продуктом реакции вл етс 4-этилдиоксап-1,3 (т. КПП. 134°С) нар ду с некоторым количеством гидроксплосодержащих веществ и незначительным количеством смолы.Dialysis of the reaction mixture indicates that, under these conditions, formaldehyde reacts to 80-85%. The main product of the reaction is 4-ethyldioxap-1,3 (t. CAT. 134 ° C), along with some hydroxy-containing substances and a small amount of resin.
(30%) при температуре 350-375°С и объемной скорости 0,5 л/л кат-час (счита на жидкий диоксан).(30%) at a temperature of 350-375 ° C and a space velocity of 0.5 l / l cat-hour (counting on liquid dioxane).
Процент разложени за проход составл ет при этом на пропущенный этилдноксан при выходе ииперилена до 90% от теории на разложеиный диоксан и до 10% бутена-1 на тот же дпоксан. Бутен-1 может быть отделен от пинерилеиа и снова направлен в реакцию .The percentage of decomposition per pass is thus on the missed ethyldoxane when the iperylene is released up to 90% of the theory on decomposed dioxane and up to 10% of butene-1 on the same dpoxane. Butene-1 can be separated from pinerleia and returned to the reaction.
Контактирование ведетс в течение 2- 4 час, после чего реактор переключаетс на регенерацию иаро-воздущной смесью при той же температуре 350-375°С в течение 1 -Contacting is maintained for 2-4 hours, after which the reactor is switched to regeneration with an air-air mixture at the same temperature of 350-375 ° C for 1 -
2 час. При этих услови х катализатор может работать длительное врем .2 hours Under these conditions, the catalyst can operate for a long time.
