  2. Tetrabromoethane - Wikipedia

    en.wikipedia.org/wiki/Tetrabromoethane

    1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.

  3. Tribromoethylene - Wikipedia

    en.wikipedia.org/wiki/Tribromoethylene

    Tribromoethylene is a bromoalkene and a trihaloethylene with the chemical formula C 2 HBr 3.It can be made from 1,1,2,2-tetrabromoethane. [3]Tribromoethylene reacts with potassium hydroxide to yield dibromoacetylene via dehydrobromination, [4] this reaction is analogous to the synthesis of dichloroacetylene from trichloroethylene.

  4. Tetrabromoethylene - Wikipedia

    en.wikipedia.org/wiki/Tetrabromoethylene

    Tetrabromoethylene is a potential fungicide and bactericide on fruits. [1] It was used in mineral separation. [2] It is prepared from acetylene and bromine in multiple steps. [1] [3] One method involves dehydrobromination of pentabromoethane, other method involves bromination of dibromoethylene in chloroform. [1]

    Tetrabromide may refer to: . Carbon tetrabromide, CBr 4; Germanium tetrabromide, GeBr 4; Hafnium tetrabromide, HfBr 4; Iridium tetrabromide, IrBr 4; Neptunium ...

  6. Amine gas treating - Wikipedia

    en.wikipedia.org/wiki/Amine_gas_treating

    Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. [1] [2] [3] It is a common unit process used in refineries, and ...

  7. Bromoethane - Wikipedia

    en.wikipedia.org/wiki/Bromoethane

    H 2 C=CH 2 + HBr → H 3 C-CH 2 Br. Bromoethane is inexpensive and would rarely be prepared in the laboratory. A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids. An alternate route involves refluxing ethanol with phosphorus and bromine; phosphorus tribromide is generated in situ. [4]

  8. STP (motor oil company) - Wikipedia

    en.wikipedia.org/wiki/STP_(motor_oil_company)

    Chemical Compounds was founded in 1953 by three businessmen, Charles Dwight (Doc) Liggett, Jim Hill and Robert De Hart, [2] with $3,000 in start-up capital in St. Joseph, Missouri. Their sole product was STP Oil Treatment; the name was derived from “Scientifically Treated Petroleum”. [3]

  9. 1,1,2,2-Tetrachloroethane - Wikipedia

    en.wikipedia.org/wiki/1,1,2,2-Tetrachloroethane

    It is also produced by direct chlorination or oxychlorination utilizing ethylene as feedstock and by catalytic chlorination of ethane or chlorination of 1,2- dichloroethane. [8] 1,1,2,2-Tetrachloroethane is always produced in closed systems to obtain the highest yield. Common side products that are created during the synthesis of 1,1,2,2 ...
