Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature.

3-Methyl-3-penten-2-one is an unsaturated aliphatic ketone. It is an isomer of mesityl oxide and isomesityl oxide. It is a precursor of 3-methyl-2-pentanone (methyl sec-butyl ketone) and is obtained by acid-catalyzed dehydration of 4-hydroxy-3-methyl-2-pentanone. It is used as an intermediate in organic chemistry syntheses. [1]

The branched isomers are 2-methylbut-1-ene, 3-methylbut-1-ene (isopentene), and 2-methylbut-2-ene (isoamylene). Isoamylene is one of the three main byproducts of deep catalytic cracking (DCC), which is very similar to the operation of fluid catalytic cracking (FCC).

ch 2 =ch 2 + ch 3 ch=chch 3 → 2 ch 2 =chch 3 Transition metal catalyzed hydrovinylation is another important alkene synthesis process starting from alkene itself. [ 31 ] It involves the addition of a hydrogen and a vinyl group (or an alkenyl group) across a double bond.
Polymethylpentene melts at ≈ 235 °C. It has a relatively low density (0.84 g/cm 3) among plastics and is transparent. It has low moisture absorption, and exceptional acoustical and electrical properties. [citation needed] Its properties are reasonably similar to those of other polyolefins, although it is more brittle and more gas permeable.
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230, Novec 649, and FK-5-1-12. It is also known as ...
