Изобретение относитс  к спасобавд ошределени  мышь ковистого ангидрида.BACKGROUND OF THE INVENTION The invention relates to the recovery of a mouse for malchid anhydride.

Известен способ определени  трехвал1ентного мышь ка титрованием ело броматом кали . . Однако этим способом ацределить мышьЯКО1В1ИСТЫЙ а1Н:ГИ1дрид в париж-амой зелени нельз .There is a known method for determining a trivalent mouse by titration with potassium bromate. . However, using this method, it would not be possible to distribute the mouse-aYA1B1GLY a1H: GI1drid in Paris-Amy greenery.

По пре1длага0мому способу дл  одраделени  мышь ковистого ангидрнда .в парижской зелени nipoi y анализируемого вещества обрабатьгвают при кип чении спиртом с последующим фильтрованием нолучанного спиртового раствора мышь кoJBиcтoгo ангидрида и титрованием филыпрата бромафом .кали .According to the previous method, in order to isolate a mouse of a malignant anhydride.

С|вобс дный АззОз в присутсивии св. за1н ого М|ОЖ1НО определить на оан10:Ва1Нии различной растворимости мышь ковистого ангидрида в парижской зелени (Си(СНзСОО)2 3Cu(AsO2)2) в .метиловом, этиловом слиртах и и,х гомологах , а также в непредельных спиртах.S | Vobss dny AzzOz in the presence of St. determine the following for various solubilities of mouse covalent anhydride in Paris greenery (Cu (CH3COO) 2 3Cu (AsO2) 2) in methyl, ethyl, and x and homologues, as well as in unsaturated alcohols.

Парижска  зелень практически не растворима при тбм|пературе кипени  в 96-100% этиловО(М спирте, в то врем  как 10 г мышь ковистого ангидрида растпвар ют в 1 .Parisian greens are practically insoluble at tbm | boiling point in 96-100% ethyl alcohol (M alcohol, while 10 g mouse malleus anhydride is dissolved in 1.

И|рИ(Мер. В круглодонную колбу с притертой пробкой и ХОЛОДИЛЫНИ1КОМ наливают 50 мл этилового спирта, в который 1ввод т 1,25 г парижской зелени. Смесь с обратньим холодильником ки1ПЯт т «а вод ной бане(Mer.) In a round bottom flask with a ground in stopper and a REFRIGERATOR, 50 ml of ethyl alcohol is poured in which 1 injected 1.25 g of Paris greens. A mixture with a reverse fridge is placed in a water bath

1 час. После этого содержимое колбы охлаждают , фильтруют на воронке Бюхнера через плотный фильтр. Осадок промывают 96- 100% С:Пирто1М. Л иа|кость сливают в мершую колбу ем1К10стью 100 мл и довод т до мегки. Берут 50 мл фильтрата, титруют его 0,1 н. раствороэд КВгОз и вычисл ют процентное содер жание по формуле1 hour. After that, the contents of the flask are cooled, filtered on a Buchner funnel through a dense filter. The precipitate is washed with 96-100% C: Pyrto1M. The luminaire is poured into a rychu flask with a volume of 100 ml and is brought to the flask. Take 50 ml of filtrate, titrate it with 0.1 n. solution of KVOZ and calculate the percentage by the formula
