To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. Crude NBS gives better yield in the Wohl-Ziegler reaction. In other cases, impure NBS (slightly yellow in color) may give unreliable ...
chlorine- a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water)
What is the density of chlorine gas?Chlorine GasChlorine is a chemical element with atomic number 17. It is the second largest of the halogens. It is very toxic as a gas and was used as a weapon in World War I. It has a yellow-green color....

Biocides are added to fracking fluidsto kill bacteria that can corrode well casings, limit efficacy of oil and gas extraction, and produce highly toxic hydrogen sulfide gas. Is alcohol a biocide? Ethanol is one example and is included inthe biocidal product disinfectant. There are 22 biocidal pro...
What is Bromine? What is Krypton? Discussion Comments Byanon207899— On Aug 21, 2011 Sodium Fluoride is poison, plain and simple and they put it in our water supply and toothpaste to "make our teeth stronger". Do your research and stop using fluoride based toothpastes, unless they use cal...
To improve the physical properties of the lead compound 12, the bromine atom was replaced with an acetyl group, thus reducing the overall lipophilicity of the molecule. Anyway, at this stage it was observed that this substitution was optimal when a methyl function was also present at position ...
"Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas in small, confined spaces," Jeff Gearhart, research director at the Ecology Center, said in awritten statement. "Since these chemicals are not regulated, consumers have no way of knowing...
