Description
В ОСНОВНОМ патенте № 17831 описан способ получени индикатора дл определени концентрации водородных ионов.Patent No. 17831 describes a method for producing an indicator for determining the concentration of hydrogen ions.
По насто щему способу изготовлен индикатор дл той же цели, диапазон действи которого повышаетс до 3,0. Индикатор вл етс смесью монокалиевых, монолитиевых или мононатриевых солей дибромтимолсульфонфталеина, ортокарбоксибензолазопарадиметиланилина (метилоранж ) и парасульфобензолазопарадиметиланилина (метилрот).According to the present method, an indicator is manufactured for the same purpose, the range of which is increased to 3.0. The indicator is a mixture of monopotassium, monolithium or monosodium salts of dibromothymolsulfonphthalein, orthocarboxybenzene paradimethylaniline (methyl orange) and parasulfobenzolazoparadimethylaniline (methylrot).
Пр,лмеры.1. 8 объемных частей водного раствора монокалиевой или монолитиевой соли дибромтимрлсульфонфталеина (бромтимолблау) - концентраци 0,, счита на свободную кислоту.Pr, lmer.1. 8 parts by volume of an aqueous solution of dibromtimrlsulfonphthalein monopotassium monolithium salt (bromthymolblau) - concentration 0, calculated as free acid.
2.3 объемных части водного раствора монокалиевой или монолитиевой соли ортокарбоксибензолазопарадиметиланилина (метилрот)-концентраци 0,02%, счита на свободную кислоту.2.3 parts by volume of an aqueous solution of the mono potassium or monolithium salt of orthocarboxybenzene paradimethylaniline (methylrot) 0.02% concentration, calculated as free acid.
3.2 объемные части водного раствора монокалиевой или монолитиевой соли парасульфобензолазопарадиметилан лина (метилоранж )-концентраци О, , счита на соль метилоранжа.3.2 volumetric parts of the aqueous solution of the para-sulfobenzolazoparadimethylanine monokalium or monolithium salt (methyl orange) concentration O, based on the methyl orange salt.
Примечание. Растворителем может быть также и водный этиловый спирт.Note. The solvent can also be aqueous ethyl alcohol.
Цветовые переходы индикатора: от красного цвета к синему цвету.Indicator color transitions: from red to blue.
Диапазон действи -От ,0 до РН 8,5.The range of action is From, 0 to PH 8.5.
Чувствительность: ,3.Sensitivity:, 3.
Предмет изобретени .The subject matter of the invention.
Видоизменение способа приготовлени индикатора дл определени концентрации водородных ионов, охарактеризованного в патенте № 17831, отлнчающеес тем, что, с целью расширени диапазона действи индикатора, дл приготовлени такового примен ют смесь монокалиевой (или монолитиевой ) соли дибромтимолсульфонфталеина , ортокарбоксибензолазопарадиметиланилина и парасульфобензолазопарадиметиланилина в водном или спиртовом растворе.A modification of the method of preparing an indicator for determining the concentration of hydrogen ion as defined in patent № 17831, otlnchayuschees in that, in order to expand the range of action of the indicator, for the preparation thereof is applied a mixture of monopotassium (or monolithium) salts dibromtimolsulfonftaleina, ortokarboksibenzolazoparadimetilanilina and parasulfobenzolazoparadimetilanilina in an aqueous or alcoholic solution .
