Isingeniso
I-3,5-difluorobenzaldehyde iyinhlanganisela ye-organic ne-chemical formula C7H4F2O. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Izakhiwo: I-3,5-difluorobenzaldehyde iyisici esiqinile esingenambala ukuya kokuphuzi esinephunga elikhethekile lephenone. Inokuminyana okungu-1.383g/cm³, indawo yokuncibilika engu-48-52°C, kanye nephuzu elibilayo elingu-176-177°C. I-3,5-difluorobenzaldehyde ayincibiliki emanzini, kodwa incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-ether, ne-benzene.
Ukusetshenziswa: I-3,5-difluorobenzaldehyde ivamise ukusetshenziswa njengendawo ephakathi ku-organic synthesis. Ingasetshenziselwa ukuhlanganisa izinhlanganisela eziphilayo eziqukethe i-fluorine, ikakhulukazi ukusabela kwamakhemikhali okwethula ama-athomu e-fluorine abe ama-molecule ephilayo. Ngaphezu kwalokho, ingasetshenziswa futhi njengengxenye yokwenziwa yezidakamizwa, izibulala-zinambuzane kanye nodayi.
indlela yokulungiselela: indlela yokulungiselela ye-3,5-difluorobenzaldehyde ingatholakala ngokusabela i-3,5-difluorobenzyl methanol nge-asidi aldehyde reagent (njenge-trichloroformic acid, njll.). Izindlela ezithile zokwenziwa zingabhekisa ku-Organic Synthesis Handbook kanye nemibhalo ehlobene.
Ulwazi lokuphepha: I-3,5-difluorobenzaldehyde iyikhemikhali futhi idinga ukusetshenziswa ngokuphepha. Iyacasula futhi iyagqwala futhi ingabangela ukulimala kwamehlo, isikhumba kanye nesistimu yokuphefumula. Izinto zokuzivikela ezifanele ezifana nezibuko, amagilavu nezihlangu zobuso kufanele zigqokwe ngesikhathi sokusetshenziswa. Landela izinqubo zokuphepha zaselabhorethri futhi ugcine, uphathe futhi ulahle inhlanganisela ngendlela efanele. Uma kwenzeka ukuthintana ngephutha noma ukumunca, funa usizo lwezokwelapha ngokushesha futhi unikeze ulwazi oludingekayo kudokotela.
