Usage

Uses

Used in Water Disinfection:
Dichloramine B is used as a disinfectant in public water systems for [application reason] its ability to kill microorganisms and ensure water safety. It is particularly employed in chloraminated water, where it serves as an intermediate in the disinfection process.
Used in Chemical Research:
Dichloramine B is used as a research compound for [application reason] its role in understanding the reactions between ammonia and chlorine, as well as its involvement in the formation of other chemical species such as monochloramine and nitrogen trichloride. This knowledge can be crucial for developing more effective and safer water treatment methods.

Copper-promoted iodovinylation of amides: synthesis of β-functionalized enamides

We studied the addition of nitrogen radicals to ynol ethers in order to form β-functionalized enamides. Poor yields are reported. On the other hand, we observed that copper coupling between 1,2-diiodoethene and various amides leads to β-functionalized enamides in high yields with complete stereocontrol.

Determination of quantum yield for the photolysis of aqueous solution of chloramine-B

Photolysis of aqueous solution of chloramine-B (0.01-0.0002 mol dm-3) is studied with a UV light source and the products have been identified. A suitable photolytic mechanism is suggested based on the observed results. The photolytic decomposition obeys first order kinetics. Quantum yield for the photolysis of chloramine-B is reported.
