Description
СПОСОБ ПОЛУЧЕНИЯ ГИДРОПЕРЕКИСИ ТЕТРАЛИНАMethod of producing tetrapalin hydroperoxide
Известен способ получени гидронерекиси тетралина путем окислени последнего кислородом воздуха в присутствии инициаторов. Однако выход продукта незначителен - около 20%.A method of producing tetralin hydroneoxide is known by oxidation of the latter with oxygen in the presence of initiators. However, the product yield is insignificant - about 20%.
Предлагаемый способ отличаетс тем, что в качестве инициатора используют резинат марганца . Это позвол ет увеличить выход гидроперекиси тетралина до 35-40%.The proposed method is characterized in that manganese resins are used as the initiator. This allows increasing the yield of tetralin hydroperoxide to 35-40%.
При осуществлении способа подвергают автоокислепию тетралин молекул рным кислородом при 68-70°С в присутствии резината марганца.In the implementation of the method, autooxide of tetralin is subjected to molecular oxygen at 68-70 ° C in the presence of manganese resins.
Пример. В реактор, снабженный л- ешалкой , обратным холодильником с хлоркальциевой трубкой, термометром н трубкой дл подачи кислорода, загружают свежеперегнанный тетралин (температура кипени 56-59СExample. Freshly distilled tetralin (boiling point 56-59 ° C) is charged to a reactor equipped with a stirrer, a reflux condenser with a calcium chloride tube, a thermometer and an oxygen supply tube.

при 25 мм рт. ст.; пЪ 1,5430; d4 0,9707) и резинат марганца (0,2% от веса тетралина), причем сначала загружают половину рассчитанного резината марганца. Смесь нагревают до 68-70°С, после чего включают мешалку и начинают пропускать предварительно очищенный и просущенный кислород. Через б, 12 и 18 час в реактор добавл ют равными порци ми оставшийс резинат марганца. Выход гидроперекиси тетралина около 40%.at 25 mm Hg. v .; pb 1.5430; d4 0.9707) and manganese resins (0.2% by weight of tetralin), with half of the calculated manganese resins being loaded first. The mixture is heated to 68-70 ° C, after which the stirrer is turned on and the previously purified and dried oxygen is started to pass. After b, 12 and 18 hours, the remaining manganese resinate is added to the reactor in equal portions. The yield of tetraline hydroperoxide is about 40%.
