Cyanuric acid or 1,3,5-triazine-2,4,6-triol is a chemical compound with the formula (CNOH) 3.Like many industrially useful chemicals, this triazine has many synonyms. This white, odorless solid finds use as a precursor or a component of bleaches, disinfectants, and herbicides.
To extend their disinfectant usefulness and persistence in outdoor settings, swimming pools treated with one or more of the inorganic forms of chlorine-releasing compounds can be supplemented with cyanuric acid – a granular stabilizing agent capable of extending the active chlorine residual half-life (t ½) by four to sixfold. [17]
Thiocyanuric acid precipitates from warm, acidic solutions of thiocyanic acid. A modern synthesis begins instead with a preformed ring: cyanuric chloride reacts with sodium hydrosulfide to give table salt and thiocyanuric acid. [3] The compound is mildly acidic, with pKa's of 5.7, 8.4, and 11.4. [3] Various salts of (HNC=S) − 3 have been ...
Acid chlorides can be reduced to give aldehydes with sterically hindered hydride donors. The reducing agent DIBAL-H (diisobutylaluminium hydride) is often used for this purpose, although it normally reduces any carbonyl. DIBAL-H can selectively reduce acid chlorides to the aldehyde level if only one equivalent is used at low temperatures. [12]
KOCN is prepared by heating urea with potassium carbonate at 400 °C: . 2 OC(NH 2) 2 + K 2 CO 3 → 2 KOCN + (NH 4) 2 CO 3. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO 2 CNHC(O)NH 2), as well as unreacted starting urea, but these species are unstable at 400 °C.
Reductions with hydrosilanes are methods used for hydrogenation and hydrogenolysis of organic compounds.The approach is a subset of ionic hydrogenation.In this particular method, the substrate is treated with a hydrosilane and auxiliary reagent, often a strong acid, resulting in formal transfer of hydride from silicon to carbon. [1]
Cyanuric chloride is employed as a reagent in organic synthesis for the conversion of alcohols into alkyl chlorides, [8] and carboxylic acids into acyl chlorides: [9]. It is also used as a dehydrating agent, e.g. in the conversion of amides to nitriles, [10] and for the activation of carboxylic acids for reduction to alcohols.
Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is a chemical compound widely used as a cleansing agent and disinfectant. [1] It is a colorless, water-soluble solid, produced as a result of reaction of cyanuric acid with chlorine.
