Mawu Oyamba
3,5-difluorobenzaldehyde ndi organic pawiri ndi mankhwala chilinganizo C7H4F2O. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Katundu: 3,5-difluorobenzaldehyde ndi yopanda mtundu mpaka yolimba yachikasu yokhala ndi fungo lapadera la phenone. Ili ndi kachulukidwe ka 1.383g/cm³, malo osungunuka a 48-52°C, ndi kuwira kwa 176-177°C. 3,5-difluorobenzaldehyde sisungunuka m'madzi, koma imasungunuka mu zosungunulira za organic monga ethanol, ether, ndi benzene.
Ntchito: 3,5-difluorobenzaldehyde amagwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana zokhala ndi fluorine, makamaka pamachitidwe amankhwala omwe amayambitsa maatomu a fluorine kukhala mamolekyu achilengedwe. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chopangira chapakatikati chamankhwala, mankhwala ophera tizilombo ndi utoto.
njira yokonzekera: njira yokonzekera 3,5-difluorobenzaldehyde ikhoza kupezedwa pochita 3,5-difluorobenzyl methanol ndi asidi aldehyde reagent (monga trichloroformic acid, etc.). Njira zenizeni zopangira zitha kutanthauza buku la Organic Synthesis Handbook ndi zolemba zina.
Zambiri zachitetezo: 3,5-difluorobenzaldehyde ndi mankhwala ndipo imayenera kugwiritsidwa ntchito mosamala. Zimakwiyitsa komanso zimawononga ndipo zimatha kuwononga maso, khungu komanso kupuma. Zida zodzitetezera zoyenerera monga magalasi, magolovesi ndi zishango zakumaso ziyenera kuvalidwa mukamagwiritsa ntchito. Tsatirani njira zachitetezo cha labotale ndikusunga, gwirani ndi kutaya pawiriyo moyenera. Ngati mwakumana mwangozi kapena kumwa mowa, funsani kuchipatala mwamsanga ndikupereka chidziwitso chofunikira kwa dokotala.
