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)
Element number 17 in the periodic table, chlorine is one of a group of elements that share similar chemical properties known as the halogens, with the other members being fluorine, bromine, iodine and astatine. The gas dissolves in water, forming a mixture of hypochlorous and hydrochloric acids...

Do metals off gas? So choosing real wood furniture, or furniture from metal, whichdoesn't off gas. Even solid wood furniture made with toxic glues and adhesives isn't good. So check to make sure no-VOC paints, sealants and stains are used. ...
What is the chemical element bromine? What element is lawrencium? Which chemical element has the symbol Na? Which chemical element has the symbol Pb? Which chemical element has the symbol Fe? What is the chemical symbol for iron? How many electrons are in sulfur?
"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...
30. The intermediate compound according to claim 29, wherein, in the general formula II, R1 is bromine or iodine; R2 is selected from bromine, iodine, trifluoromethyl, and difluoromethoxy; R3 is CF3 or CF2CF3; R4 is selected from CH2CN, CH2CH2CN, CH2CH2CH2CN, CH2CH2CH2CH2CN, CH(...
Answer PBDPE and PBBs are typical flame retardants to be used for plastics materials. Meanwhile it is preferable to avoid using those retardants in the products because they are prone to generate toxic substances, such as dioxins and freon gas. ...
