Description
Предлагаемое изобретение касаетс способов получени солей йодноватой из свободного иода путем окислени последнего хлорноватокислыми сол ми в сернокислой среде.The present invention relates to methods for producing salts of iodic acid from free iodine by oxidizing the latter with chloric acid salts in a sulfate medium.
С целью получени на холоду йодноватой кислоты или ее комплекса, в предлагаемом способе окисление ведут в присутствии раствора какого-либо хлорида. В дальнейшем, дл осаждени остатков йодноватой кислоты из оставшегос раствора , к последнему добавл ют поташ.In order to obtain iodic acid or its complex in the cold, in the proposed method, the oxidation is carried out in the presence of a solution of some chloride. Subsequently, potash is added to the latter to precipitate residues of iodic acid from the remaining solution.
Способ заключаетс в том, что смесь, состо ща из свободного иода, какихлибо хлорноватокислых солей (например бертолетовой соли, хлорноватокислого ватри и т. п.), насыщенного раствора того или иного хлорида (хлористый калий, хлористый натрий, хлористый магний, хлористый кальций и т. п.) и концентрированной серной кислоты, помещают в скл нку или иную подход щую., посуду и оставл ют сто ть при обыкновенной температуре. По истечении, примерно, 50 часов заканчиваетс процесс окислени иода в соль йодноватой кислоты. Осевший т желый осадок соли йодноватой кислоты отфильтровывают, а оставшийс раствор обрабатывают поташом,The method consists in the fact that a mixture consisting of free iodine, any chloric acid salts (for example, potassium chlorate, vatric chlorate, etc.), a saturated solution of one or another chloride (potassium chloride, sodium chloride, magnesium chloride, calcium chloride and etc.) and concentrated sulfuric acid are placed in a bottle or other suitable container and left to stand at ordinary temperature. After about 50 hours, the oxidation of iodine to the salt of iodic acid is completed. The precipitated heavy precipitate of iodic acid salt is filtered off, and the remaining solution is treated with potash,
в результате чего происходит осаждение оставшихс в растворе количеств соли йодноватой кислоты.as a result, precipitations of residual salts of iodic acid salt remain in the solution.
ПримЪр 1. Берут 150 г иода, 120 / бертолетовой соли, 300 куб. f-.i насыщенного раствора хлористого натра и 60 г концентрированной серной кислоты. Смесь эту, помещают в скл нку с притертой пробкой и оставл ют сто ть при обыкновенной температуре. Через 50 часов окисление иода заканчиваетс .,Example 1. Take 150 g of iodine, 120 / potassium chlorate, 300 cu. f-.i saturated solution of sodium chloride and 60 g of concentrated sulfuric acid. This mixture is placed in a flask with a ground stopper and left to stand at ordinary temperature. After 50 hours, the oxidation of iodine is complete.
Образовавшийс т желый осадок йодноватого кали отфильтровывают, а к раствору добавл ют еще 35 поташа, после чего снова через некоторое врем вьшадает осадок. Оба осадка имеют один и тот же состав, при чем выход получаетс 95-98 о от теоретического.The resulting heavy precipitate of potassium iodate is filtered off, and 35 more potash are added to the solution, after which the precipitate disappears again after some time. Both sediments have the same composition, and the yield is 95-98 o from the theoretical.
Из полученной соли йодноватой кислоты нейтрализацией едким калием или поташом получают, как обычно, чистую среднюю соль. Дл целей окислени может быть вполне использован полученный комплекс 1 ОДНОЕатой соли без вс кой дальнейшей обработки.From the obtained salt of iodic acid by neutralization with caustic potassium or potash, as usual, a pure middle salt is obtained. For the purposes of oxidation, the obtained complex of 1 ONE salt can be fully used without any further processing.
Пример 2. Берут 127 г иода, концентрированного раствора хлорноватонатровой соли, содержащего 90 NaClos, 45 серной кислоты и 300 wT. м 25,о-ног(Example 2. Take 127 g of iodine, a concentrated solution of potassium chloride, containing 90 NaClos, 45 sulfuric acid and 300 wT. m 25 o-legs (

1. Способ получени солей йодноватой кислоты из свободного йода при окислении ,- fero ХАОрноватокислыми сол ми в сернокислой среде, отличающийс тем, что окисление ведут в присутствии раствора какого-либо хлорида, с целью получени уже на холоду соли йодноватой кислоты или ее комплекса.1. The method of obtaining salts of iodic acid from free iodine during oxidation is fero CHA ortho-acid salts in a sulfate medium, characterized in that the oxidation is carried out in the presence of a solution of some chloride, with the aim of obtaining the iodic acid salt or its complex in the cold.
2. Прием выполнени - способа, рзнаг ченного в п. 1, отличающийс тем, что к отставшему раствору, после выпадени соли иоднрватой кислоты, добавл ют поташ дл осаждени новых количеств йодноватой кислоты.2. Acceptance of the method described in paragraph 1, characterized in that potash is added to the lagging solution, after precipitation of the hydrochloric acid salt, to precipitate new quantities of iodic acid.
