Abstract

Метод за инхибиране полимеризацията на спрегнати диени при отделянето им чрез дестилационна десорбция от въглеводородна смес, в която се съдър жат, при използване на диметилформамид като селективен разтворител и при висока температура, характеризиращ се с това, че като полимеризационен инхибитор се използва смес от фурфурал и фурфуралови поликондензати, чието количество, изчислено на база общото количество на разтворителя, се поддържа по време на процеса на дестилационна десорбция в границите от 0,01 до 2% тегл.фурфурал и от 0,5 до 10% тегл. Фурфуралови поликондензати при общо количество на горната инхибираща смес от 1 до 12% тегловини. Патентните претенции са формулирани в 2 точки
