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 ...

But according to a new study from the nonprofit Ecology Center and HealthyStuff.org, what you might actually be sniffing are toxic fumes from chemicals used to create the car interior. "Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas i...
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)
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...
Complicating this, the most commonly used tests (breath tests measuring levels of hydrogen and methane gas) still have fairly high rates of false negatives (meaning the test results come back as negative but you actually do have the disease) (7). ...
