이산화염소(기체) C화학적 특성, 용도, 생산
화학적 성질
Chlorine dioxide,CI02, is a yellow-reddish gas.It is a very effective bleaching and water treatment agent. Chlorine dioxide is preparedby the reaction of chlorine and sodium chlorite. It is quite unstable and is commonly prepared immediately before use.물리적 성질
Yellow to red-yellow gas at room temperature; pungent chlorine-like odor; density 9.99 g/L at 11°C; liquefies to a reddish brown liquid at 11°C; liquid density 1.64 g/mL at 0°C; freezes at -59.5° C to red crystals (explodes); soluble in water, decomposes in hot water; soluble in alkalis and H2SO4.용도
Chlorine Dioxide is a gas used in bleaching and aging flour. it acts on the flour almost instantly, resulting in improved color and dough properties. because usage levels are low, the bleaching action is limited.제조 방법
Chlorine dioxide is prepared by passing nitrogen dioxide through sodium chlorate packed in a column:NaClO3 + NO2 → NaNO3 + ClO2
Also, it may be prepared by the reaction of chlorine with sodium chlorite:
2NaClO2 + Cl2 → 2ClO2 + 2NaCl
Alternatively, it may be obtained by the treatment of sodium chlorate or potassium chlorate with sulfur dioxide and sulfuric acid:
2NaClO3 + SO2 + H2SO4 → 2ClO2 + 2 NaHSO4.
생산 방법
Chlorine dioxide is manufactured from the oxidation of chlorite or the reduction of chlorate. The latter method is used for large-volume production and is carried out in strongly acidic solution using reducing agents such as NaCl, HCl, sulfur dioxide, and methanol.정의
An orange gas formed by the action of concentrated sulfuric acid on potassium chlorate. It is a powerful oxidizing agent and its explosive properties in the presence of a reducing agent were used to make one of the first matches. It is widely used in the purification of water and as a bleach in the flour and wood-pulp industry. On an industrial scale an aqueous solution of chlorine dioxide is made by passing nitrogen dioxide up a tower packed with a fused mixture of aluminum oxide and clay, down which a solution of sodium chlorate flows.위험도
Explodes when heated or by reaction with organic materials. Very irritating to skin and mucous membranes. Lower respiratory tract irritant. Broncitis.건강위험
Chlorine dioxide is highly irritating to theeyes, nose, and throat. Inhalation can causecoughing, wheezing, respiratory distress, andcongestion in the lungs. Its toxicity inhumans is moderate to high. Its irritanteffects in humans can be intense at a con centration level of 5 ppm in air. A concen tration of 19 ppm of the gas inside a bleachtank caused the death of one worker (Elkins 1959). The chronic toxicity signs are mainlydyspnea and asthmatic bronchitis, and in cer tain cases irritation of the gastrointestinaltract. Ingestion of the liquid may cause som nolence and respiratory stimulation.화재위험
Nonflammable gas; however, it is highly reactive and a strong oxidizing agent. Chlo rine dioxide explodes violently upon heating, exposure to sunlight, contact with dust, or when subjected to a spark. Detonation occurs at concentrations above 10% in air in the presence of an energy source or catalyst. It undergoes violent reactions with organic matter; explosion occurs when the mixture is subjected to shock or a spark. It reacts spon taneously with sulfur or phosphorus, caus ing ignition and/or explosion. Liquid chlorine dioxide may explode violently when mixed with mercury, caustic potash, caustic soda, or many metal hydrides. The gas reacts explo sively with fluorine and with difluoroamine (Lawless and Smith 1968).Safety Profile
Moderately toxic by inhalation. Experimental reproductive effects. Mutation data reported. An eye irritant. A powerful explosive sensitive to spark, impact, sunlight, or heating rapidly to 100℃. A powerful oxidzer. Concentrations of greater than 10% in air are explosive. Explodes on mixing with carbon monoxide, hydrocarbons (e.g., butadiene, ethane, ethylene, methane, propane), fluoramines (e.g., difluoramine, trifluoramine). Mtxtures with hydrogen explode with sparking or contact with platinum. Explodes on contact with mercury, potassium hydroxide, phosphorus pentachloride + chlorine. Ignites or explodes on contact with nonmetals (e.g., phosphorus, sulfur, sugar). Reacts violently with F2, NHF2. Reacts with water or steam to produce toxic and corrosive fumes of HCl. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINE.잠재적 노출
Chlorine dioxide is used in bleaching cellulose pulp; bleaching flour; water purification; as a liquid sterilizer in an ultrasonic cleaner.운송 방법
UN/NA 9191 Chlorine dioxide, hydrate, frozen, Hazard class: 5.1; Labels: 5.1-Oxidizer, 6.1-Poison Inhalation. Explosive: It may only be shipped in the frozen state and then only by private or contract motor carrier.비 호환성
Unstable in light. A powerful oxidizer. Chlorine dioxide gas is explosive at concentrations over 10% and can be ignited by almost any form of energy, including sunlight, heat (explosions can occur in air in temperature above 130C), or sparks, shock, friction, or concussion. This chemical reacts violently with dust, combustible materials; and reducing agents. Reacts violently with mercury, phosphorus, sulfur, and many compounds, causing fire and explosion hazard. Contact with water forms perchloric and hydrochloric acid. Corrosive to metals.폐기물 처리
Use large volume of concentrated solution of ferrous salt or bisulfite solution as reducing agent. Then neutralize and flush to sewer with abundant water.이산화염소(기체) 준비 용품 및 원자재
