페리시안화칼륨 C화학적 특성, 용도, 생산
화학적 성질
Potassium ferricyanide, also known as red potassium prussiate and red prussiate of potash, has the chemical formula C6FeK3N6 or K3[Fe(CN)6]. It is poisonous, bright red, water-soluble light-sensitive crystals that decompose when heated. The crystals are soluble in water but less so in alcohol that is used in calico printing and wool dyeing.용도
Potassium ferricyanide was used with ferric ammonium citrate to sensitize paper for the cyanotype process and mixed with hypo to make Farmer’s reducer which was used to reduce the density of silver-based images. This compound found various applications such as producing blueprints, photography, wood staining, wool dyeing, calico printing, etching liquid (Mercer's liquor), tempering iron and steel, electroplating, mild oxidizing agent in organic synthesis, and analytical chemistry.주요 응용
It is used in many amperometric biosensors as an electron transfer agent replacing an enzyme's natural electron transfer agent with the enzyme glucose oxidase. It is a major component of Murakami's etchant for cemented carbides.생산 방법
This deep red crystal was made by passing chlorine gas through a solution of potassium ferrocyanide. The oxidation of ferrocyanide yields potassium ferricyanide.Potassium ferricyanide is used as a chemical reagent and in metallurgy, photography, and pigments.일반 설명
Potassium hexacyanoferrate(III) (Potassium ferricyanide) is an alkali hexacyanoferrate. On heating, it undergoes decomposition to afford yellow-brown hexacyanoiron(III) acid. It can be prepared by the anodic oxidation of K4[Fe(CN)6].위험도
Decomposes on strong heating to evolve highly toxic fumes, but the compound itself has low toxicity.Safety Profile
Moderately toxic by ingestion. Not as toxic as the simple cyanides. Mutation data reported. Explosive reaction with ammonia, chromium trioxide (above 196°C), sodtum nitrite + heat. Violent reaction with Cu(NO3)2. Mixtures with chromium trioxide + silver grains ignite with friction. When heated to decomposition or on contact with acid or acid fumes it emits hghly toxic fumes of K2O and CN-. Used as a fmative in photography, as a metal cleaner, and for glass coatings.Purification Methods
It has been recrystallised repeatedly from hot water (1.3mL/g) and dried under vacuum in a desiccator.페리시안화칼륨 준비 용품 및 원자재
