시안산칼륨 C화학적 특성, 용도, 생산
화학적 성질
Potassium cyanate, KOCN,is colorless,water soluble crystals. Used as an herbicide and for the manufacture of drugs and organic chemicals,용도
Potassium cyanate is used as chemical intermediate and as a weed killer. It is also used for the heat treatment of metals.일반 설명
Potassium cyanate can be prepared by reacting urea with alkali hydroxide or carbonates at high temperatures.Safety Profile
Poison by intraperitoneal route. Moderately toxic by ingestion. Causes irritation of the gastrointestinal tract. An herbicide. It is said to be slowly metabolized in the body to cyanide but does not have high toxicity of cyanides. When heated to decomposition it emits very toxic fumes of CNand K2O.Purification Methods
Common impurities include ammonia and bicarbonate ion (from hydrolysis). Purify it by preparing a saturated aqueous solution at 50o, neutralising with acetic acid, filtering, adding two volumes of EtOH and keeping for 3-4hours in an ice bath. (More EtOH can lead to co-precipitation of KHCO3.) Filter, wash it with EtOH and dry it rapidly in a vacuum desiccator (P2O5). The process is repeated [Vanderzee & Meyers J Chem Soc 65 153 1961].시안산칼륨 준비 용품 및 원자재
