(Elements & Compounds) a toxic pungent greenish-yellow gas of the halogen group; the 15th most abundant element in the earth's crust, occurring only in the combined state, mainly in common salt: used in the manufacture of many organic chemicals, in water purification, and as a disinfectant ...
Today, pulp is bleached using an ‘Elemental-Chlorine Free’ (ECF) process and a ‘Totally Chlorine Free’ (TCF) process. We only use TCF because it’s the only process that is 100% free of chlorine and its compounds. Natracare is dedicated to eliminating the risk of any exposure to chl...
Active chlorine compounds are those that possess or can produce OC1− or ROC1 in solution. In addition to its germicidal action, chlorine serves to oxidize organic soils, particularly proteins, down to water-soluble fragments and so reduce foam and spot/film scores. The disulfide linkage in ...
Chlorine does not occur in the elemental state because of its high reactivity. In nature the element occurs mainly as sodium chloride in seawater. Its abundance in seawater is 1.9% by weight. It also exists as chloride in many rocks and minerals such as carnallite (KMgCl3•6H2O) and syl...
47 Chlorine-producing compounds are also used as disinfectants and water-purifying agents. Although it was recognized in the 17th century that heating ammonium chloride and nitric acid together created an irritating gas, chlorine was first described and used as a bleaching agent in the 1770s. In ...
In the presence ofcharcoal, the combination of chlorine and hydrogen takes place rapidly (but without explosion) in the dark. A jet of hydrogen will burn in chlorine with a silvery flame. Its high affinity for hydrogen allows chlorine to react with manycompoundscontaining hydrogen. Chlorine react...
Chlorine dioxide is used for several purposes,including its applications as a bleachingagent to bleach fats, oils, textiles, cellulose,paper pulp, flour, and leather. It is also usedfor purifying water; as an oxidizing agent;as an antiseptic; and in the manufacture ofmany chlorite salts. ...
