Mawu Oyamba

Cyclopentadiene (C5H8) ndi madzi opanda mtundu, onunkhira. Ndi olefin yosakhazikika yomwe imakhala yopangidwa ndi ma polima komanso yoyaka moto.

Cyclopentadiene ili ndi ntchito zosiyanasiyana pa kafukufuku wamankhwala. Itha kugwiritsidwanso ntchito ngati zopangira ma polima ndi ma rubber kuti apititse patsogolo mawonekedwe awo akuthupi ndi mankhwala.

Pali njira ziwiri zazikulu zopangira cyclopentadiene: imodzi imapangidwa kuchokera kuphulika kwa mafuta a parafini, ndipo ina imakonzedwa ndi zomwe zimachitika kapena hydrogenation ya olefins.

Cyclopentadiene ndi yotentha kwambiri komanso yoyaka, ndipo ndi madzi oyaka. Posungirako ndi kuyendetsa, njira zopewera moto ndi kuphulika ziyenera kuchitidwa kuti zisagwirizane ndi moto wotseguka komanso kutentha kwambiri. Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zophulika mukamagwiritsa ntchito cyclopentadiene. Panthawi imodzimodziyo, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi kupuma kwa nthunzi yake, kuti musapangitse mkwiyo ndi poizoni. Kukatuluka mwangozi, dulani kumene kumene kumachokera kudonthako mwamsanga ndipo yeretsani ndi zipangizo zoyamwitsa zoyenera. Popanga mafakitale, njira zoyendetsera chitetezo ndi njira zoyenera ziyenera kutsatiridwa kuti zitsimikizire chitetezo chogwira ntchito.
