Mawu Oyamba
p-Chlorovalerophenone(p-Chlorovalerophenone) ndi organic pawiri ndi mankhwala formula C11H13ClO. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:
Chilengedwe:
p-Chlorovalerophenone ndi madzi achikasu opepuka opanda utoto okhala ndi fungo lapadera la ketone. Ili ndi kachulukidwe ka 1.086g/cm³, malo otentha a 245-248 ° C, ndi kung'anima kwa 101 ° C. Sisungunuka m'madzi, sungunuka mu mowa ndi ether solvents.
Gwiritsani ntchito:
p-Chlorovalerophenone ali ndi ntchito zambiri m'munda wamankhwala. Itha kugwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic kaphatikizidwe kazinthu zina. Kuphatikiza apo, itha kugwiritsidwanso ntchito popanga mankhwala ophera tizilombo, utoto ndi mankhwala.
Njira:
p-Chlorovalerophenone ikhoza kukonzedwa ndi acylation reaction. Njira imodzi yodziwika bwino ndikuchita p-chlorobenzaldehyde ndi pentanone pansi pa mikhalidwe ya acidic kupanga p-Chlorovalerophenone.
Zambiri Zachitetezo:
p-Chlorovalerophenone yokwiyitsa khungu ndi maso, kukhudzana mwachindunji kuyenera kupewedwa. Zida zodzitetezera monga magolovesi oteteza ndi magalasi ziyenera kuvala mukamagwiritsa ntchito. Panthawi imodzimodziyo, tcheru chiyenera kuperekedwa ku chitetezo cha moto ndi zoopsa za kuphulika, ndipo kukhudzana ndi ma okosijeni amphamvu kuyenera kupewedwa. Posunga, p-Chlorovalerophenone iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino, kupewa kupsa ndi dzuwa. Ngati mutakoka mpweya kapena kumeza, pitani kuchipatala mwamsanga.
