WebTrihalomethanes are a group of four chemicals—chloroform, bromodichloromethane, dibromochloromethane, and bromoform—formed, along with other disinfection by-products, when chlorine or other disinfectants used to control microbial contaminants in drinking water react with naturally occurring methane, often derived from other forms of organic and … WebFurther, chloroform formation was inhibited by ClO2 in the presence of HOCl and citrate and the degree of inhibition depends on the ratio of ClO2/HOCl. Gas chromatograph/mass spectrometer analysis indicates that this inhibition is related to the reaction of ClO2 with beta-ketoglutaric acid to form malonic acid. bitpanda best lohnt sich https://maskitas.net

Industrially, chloroform is produced by heating a mixture of chlorine and either methyl chloride (CH3Cl) or methane (CH4). At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): bitpanda chatWebJun 11, 2024 · Basically, chloroform is stabilized with ethanol or amylene, but if a sample is dried, it will no longer contain stabilizer.
