2-Methyl-2-butene, 2m2b, 2-methylbut-2-ene, beta-isoamylene, or Trimmethylethylene is an alkene hydrocarbon with the molecular formula C 5 H 10. Used as a free radical scavenger in trichloromethane (chloroform) and dichloromethane (methylene chloride). It is also used to scavenge hypochlorous acid (HOCl) in the Pinnick oxidation.
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
For example, the relative rates of epoxidation increase upon methyl substitution of the alkene (the methyl groups increase the electron density of the double bond by hyperconjugation): ethylene (1, no methyl groups), propene (24, one methyl group), cis-2-butene (500, two methyl groups), 2-methyl-2-butene (6500, three methyl groups), 2,3 ...
George A. Kraus and co-workers were the first to use 2-methyl-2-butene as scavenger under buffered conditions for the oxidation of an aliphatic and an α,β-unsaturated aldehyde. [ 2 ] [ 3 ] Later hydrogen peroxide also proved to work to remove the hypochlorite.

2-Methyl-2-butene is often used in this context: Resorcinol and sulfamic acid are also common scavenger reagents. [6] [7] Hydrogen peroxide (H 2 O 2) can be used as HOCl scavenger whose byproducts do not interfere in the Pinnick oxidation reaction: HOCl + H 2 O 2 → HCl + O 2 + H 2 O
In short, yes, slow cookers are safe, so long as certain safety precautions are followed. "Heat and electricity are always problematic and when an appliance is old, or if the wiring is ...
