Изоб1ретение относитс  к анализу фармацевтических препаратов и может быть использоваио в контрольно-аналитических лаборатори х и аптеках.The invention relates to the analysis of pharmaceutical preparations and can be used in control laboratories and pharmacies.

Известен способ качественного определени  препаратов группы ,пиразолона-5, например антипирина, путем прибавлени  к пробе анализируемого вещества серной,кислоты и ;раствора нитрита натри  с последующим добавлением к полученному соединению раствора сульфамината аммоии , подшелачиванием до рН 9 и введением раствора 1-нафтола в щелочи.A method is known for qualitatively determining the preparations of the pyrazolone-5 group, for example, antipyrine, by adding to the sample an analyte of sulfuric acid, and sodium nitrite solution, followed by adding ammonium sulfamine solution to the resulting compound, alkalizing it to pH 9 and adding 1-naphthol solution in alkali .

Однако известный способ не специфичен дл  препаратов группы пиразолона-5.However, the known method is not specific to preparations of the pyrazolone-5 group.

С целью устранени  указанного недостатка предложено к пробе анализируемого вещества добавл ть хлорат кали  и сол ную кислоту, прибавл ть к полученному соеди ению диметиланилин и концептрироваиную сол ную кислоту . При этом раствор интенсивно окращиваетс  в малиновый цвет.In order to eliminate this drawback, it was proposed to add potassium chlorate and hydrochloric acid to the sample of the analyte, add dimethylaniline and conceptual hydrochloric acid to the obtained compound. At the same time, the solution is intensively colored in a raspberry color.

Пример. 1 мл 0,1%-ного водного раствора апальгина помещают в пробирку, добавл ютExample. 1 ml of a 0.1% aqueous solution of apalgin is placed in a test tube, add

0,1 мл насыщенного водного раствора хлората кали  и 0,5 мл концентрированной сол ной кислоты, нагревают 5 мин На кип щей вод ной бане, охлаждают, добавл ют 1 .мл диметиланилина и интенсивно взбалтывают. Реакционна  смесь приобретает желто-бурый цвет. В эту же пробирку добавл ют концентрированную сол ную кислоту до общего объема 10 мл, наблюда  по вление интенсивной малиновой окраски. Предлагаемый способ прост в осуществлении п не требует  рименепи  специального оборудовани .0.1 ml of a saturated aqueous solution of potassium chlorate and 0.5 ml of concentrated hydrochloric acid are heated for 5 minutes. In a boiling water bath, cooled, 1 ml of dimethylaniline is added and agitated vigorously. The reaction mixture turns yellowish brown. Concentrated hydrochloric acid was added to the same tube to a total volume of 10 ml, and an intense raspberry stain was observed. The proposed method is easy to implement and does not require special equipment.
