тетрагидрофураПример 3. Через реактор, заполненный катализатором - А12Оз4-10% каолина, пропускают бутандиол-1,4 с объемной скоростью 0,8 при температуре 207-210°С и атмосферном давлении. Конверси бутандиола-1,4 в указанных услови х 99,0%. Выход тетрагидрофурана 100%.tetrahydrofura Example 3. A butanediol-1.4 is passed through a reactor filled with a catalyst - A12Oz4-10% kaolin, with a bulk velocity of 0.8 at a temperature of 207-210 ° C and atmospheric pressure. Conversion of butanediol-1.4 under the specified conditions is 99.0%. The yield of tetrahydrofuran is 100%.
