Mawu Oyamba

Cycloheptene ndi organic pawiri ndi kapangidwe wapadera. Ndi cyclic olefin yokhala ndi madzi opanda mtundu omwe ali ndi zinthu zapadera.

 

Cycloheptene ili ndi kukhazikika kwapamwamba komanso kukhazikika kwa thermodynamic, koma reactivity yake yayikulu imapangitsa kukhala kosavuta kukhala ndi kuwonjezera, cycloaddition ndi polymerization reaction ndi mankhwala ena. Imakhudzidwa ndi ma polymerization pa kutentha kochepa kuti apange ma polima omwe amafunika kugwiritsidwa ntchito potentha kwambiri, mumlengalenga, kapena muzitsulo.

 

Cycloheptene ili ndi ntchito zosiyanasiyana pakufufuza zamankhwala. Angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic kwa synthesis zosiyanasiyana organic mankhwala monga olefins, cyclocarbons, ndi polycyclic hydrocarbons. Itha kugwiritsidwanso ntchito pakuchita kwa organometallic catalytic reaction, free radical reactions, ndi ma photochemical reaction, pakati pa ena.

 

Pali njira zingapo zopangira cycloheptatriene. Njira imodzi yomwe imagwiritsidwa ntchito nthawi zambiri imapezedwa ndi olefin cyclization ya cyclohexene ndipo imafuna kugwiritsa ntchito kutentha kwambiri komanso zopangira kuti zithandizire.

Iyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi magwero a kutentha ndi malawi otseguka. Pogwira ntchito, kusamala koyenera monga kuvala magalasi oteteza ndi magolovesi kumafunika kupewa kukhudzana ndi khungu ndi maso. Kukhudzana ndi okosijeni, nthunzi kapena zinthu zina zoyaka moto kuyenera kupewedwa kupewa moto kapena kuphulika.
