N-Chloropiperidine is a rare example of an organic chloramine. [5] Chloramine-T is often referred to as a chloramine, but it is really a salt (CH 3 C 6 H 4 SO 2 NClNa) derived from a chloramine. [6] Organic chloramines feature the NCl functional group attached to an organic substituent.
The chloramine solution can be concentrated by vacuum distillation and by passing the vapor through potassium carbonate which absorbs the water. Chloramine can be extracted with ether. Gaseous chloramine can be obtained from the reaction of gaseous ammonia with chlorine gas (diluted with nitrogen gas): 2 NH 3 + Cl 2 ⇌ NH 2 Cl + NH 4 Cl
Ion chromatography, a method of separating ions and ionizable polar molecules, was used to separate the chloronitramide anion from the many salts present in water samples containing it, which otherwise made it difficult to use mass spectrometry; the water salinity was higher than that of saltwater.
The compound — known as chloronitramide anion — is found in water treated with inorganic chloramines, which more than one in five Americans, or around 113 million people, drink.
About 40 years ago, researchers became aware of a chemical byproduct from water being treated with chloramine, but only with new testing have researchers been able to identify exactly what it is.
Since the 1990s, many public systems have switched to inorganic chloramine, a chlorine derivative, to purify water supplies. Systems serving about 113 million people in the U.S. use this process.
Chlorine-releasing compounds, also known as chlorine base compounds, is jargon to describe certain chlorine-containing substances that are used as disinfectants and bleaches. They include the following chemicals: sodium hypochlorite (active agent in bleach ), chloramine , halazone , and sodium dichloroisocyanurate . [ 2 ]
For more than four decades, scientists have noticed a mysterious chemical in the treated drinking water of millions of people in the United States, but no one’s been able to pinpoint exactly ...
