  2. 1-Butene - Wikipedia

    en.wikipedia.org/wiki/1-Butene

    1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...

  3. 2-Ethyl-1-butanol - Wikipedia

    en.wikipedia.org/wiki/2-Ethyl-1-butanol

    The branching in 2-ethyl-1-butanol makes it harder to crystallize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.

  4. But-2-ene - Wikipedia

    en.wikipedia.org/wiki/But-2-ene

    But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis/trans-isomerism (also known as (E/Z)-isomerism); that is, it exists as two geometric isomers cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene). It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization ...
