(54) СПОСОБ ОЧИСТКИ ГИПОХЛОРИТА НАТРИЯ(54) METHOD FOR CLEANING SODIUM HYPOCHLORITE

1one

Изобретение относитс  к технологии очистки гипохлорита натри , йсподьзуемого в качестве окислителей в органическом синтезе к отбеливателей .This invention relates to the purification of sodium hypochlorite, which is used as oxidizing agents in organic synthesis to bleach.

Известен способ очистки гипохлорита от примесей, в частности от окислов железа, путем отстаивани  раствора гипохлорита и последующим отделением примесей фильтрацией 1.A known method for purifying hypochlorite from impurities, in particular from iron oxides, by settling the hypochlorite solution and then separating impurities by filtration 1.

Недостатком известного способа  вл етс  больша  продолжительность процесса от 2 до 5 дней, а также необходимость использовани  громоздкого оборудовани .The disadvantage of this method is the long process time from 2 to 5 days, as well as the need to use bulky equipment.

Целью изобретени   вл етс  упрощение способа и,интенсификаци  процесса;The aim of the invention is to simplify the process and, to intensify the process;

Поставленна  цель достигаетс  тем, что очистку гапохлорита натри  от окислов железа Вёдут адсорбцией их карбоксильной ионообмешой смолой в натриевой форме КБ-2 или КБ-4 The goal is achieved by the purification of sodium hapochlorite from iron oxides by adsorption by their carboxylic ion-resin with sodium resin in the form of CB-2 or KB-4.

Отличительными признаками  вл ютс  удаление окислов железа адсорбцией и используемьй дл  этого адсорбент.Distinctive features are the removal of iron oxides by adsorption and the adsorbent used for this.

Указанньй отличи  позвол ют упростить способ за счет исключени  необходимости использовани  громоздкое оборудование, а также интенсифицировать процесс, продолжительность которого определ етс  только скоростью фильтращш раствора через слой смолы и составл юща  100 МП/мин и выше.These differences simplify the method by eliminating the need to use bulky equipment, and also intensify the process, the duration of which is determined only by the speed of the solution through the resin bed and which is 100 MP / min.

П р и м е р 1. В Колонку диаметром 20 ммPRI me R 1. In the column with a diameter of 20 mm

и высотой 100 см загружают карбоксильную ионообменную смолу КБ-4 высотой 8-10 см. Через колонку пропускают раствор гипохлорита натри , содержащего активного хлора 70 г/л. свободной щелочи 15 г/ч, окислов железа .and a height of 100 cm is charged with a carboxylic ion exchange resin KB-4 with a height of 8-10 cm. A solution of sodium hypochlorite containing 70 g / l active chlorine is passed through the column. free alkali 15 g / h, iron oxides.

50 мг/л. Скорость фильтрации через слой смолы при высоте столба жидкости 80 см составл ет 80 см. На единице объема смолы счищаю 500 объемов гипохлорита натри . Содержание окислов железа в фильтрате 0,5 мг/л.50 mg / l. The filtration rate through the resin bed with a liquid column height of 80 cm is 80 cm. I clean off 500 volumes of sodium hypochlorite per unit volume of resin. The content of iron oxides in the filtrate is 0.5 mg / l.

Регенерацию смольг провод т промывкой ее 2-5%-ным сол нокислым раствором при встр хивании.The smolg regeneration is carried out by washing it with a 2-5% hydrochloric acid solution with shaking.

П р и м е р 2. Через колонку с высотой сло  смолы КБ-2 2500 мм пропускают раствор гипохлорита с концентрацией, указаннойPRI mme R 2. Through the column with the height of the layer of resin KB-2 2500 mm pass the solution of hypochlorite with a concentration specified

в примере I.in example I.

При этом скорость фильтрации составл ет 18 мг/мин, содержание окислов железа в фильтрате составл ет 0,38 мг/л.The filtration rate is 18 mg / min, the content of iron oxides in the filtrate is 0.38 mg / l.
