Claims (1)
- Способ относится к непрерывному производству двуокиси хлора посредством реакции хлората щелочного металла, серной кислоты или другой минеральной кислоты, свободной от хлора, и перекиси водорода в качестве восстановителя для образования двуокиси хлора в водной реакционной среде. Двуокись хлора образуется по крайней мере на одной стадии реакции, содержащей по крайней мере один реакционный сосуд, посредством подачи хлората щелочного металла, кислоты, перекиси водорода и инертного газа в упомянутый реакционный сосуд, причем по существу в отсутствие добавленных ионов хлора, поддержания водной реакционной среды в реакционном сосуде под давлением примерно 400 мм - 900 мм рт.ст., при температуре примерно 35 - 1000°С, при кислотности в пределах примерно 4 - 14 N и концентрации хлората между примерно 0,05 моль/л до насыщения, удаления двуокиси хлора, кислорода и инертного газа и обедненной водной реакционной среды из реакционной зоны без значительной кристаллизации сульфата щелочного металла.
