Abstract

Метод за получаване на третични олефини от съответните третични алкилетери на база на алкохоли с един до шест въглеродни атома и третичен олефинов радикал с четири до седем въглеродни атома чрез контактуване на етера с катализатор, представляващ модифициран активен алуминиев окис, при температура от 100 до 250'с и налягане от 1 до 10 кг/см2, характеризиращ се с това, че процесът се провежда в присъствие на катализатор, представляващ алуминиев окис, промотиран с тетраметил или тетраетилортосиликат, при количество на промотора, изразено като силициев двуокис от 1 до 20 тегл.%, Спрямо общото тегло на катализатора. Патентните претенции са формулирани в 4 точки
