2-FLUORO-5-NITRO-6-PICOLINE (CAS# 18605-16-8) Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali C6H5FN2O2. Okulandelayo yincazelo yobunjalo bayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
Ikristalu engenambala ukuya kokuphuzi okuphaphathekile noma okuqinile okuyimpuphu. Iyakwazi ukusha lapho kushiswa khona izinga lokushisa lasekamelweni, ayincibiliki emanzini, futhi iyancibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-dichloromethane.

Sebenzisa:
iyindawo ebalulekile esetshenziswa kabanzi ekuhlanganiseni nasekukhiqizeni izibulala-zinambuzane. Ingasetshenziselwa ukuhlanganisa izinhlanganisela ezihlukahlukene zezinto eziphilayo, njengemithi, odayi, izimonyo, njll. Ngaphezu kwalokho, ibuye isetshenziswe njengesithako esisebenzayo kwizibulala-zinambuzane, futhi inemiphumela emihle yokubulala izinambuzane kanye neHerbicidal kwezinye izinambuzane nokhula.

Indlela:
Kunezindlela eziningi zokulungiselela, enye yazo evamile itholakala ngokusabela kwe-1-amino -2-fluorobenzene ne-nitric acid. Inqubo ethile yokulungiselela iyinkimbinkimbi futhi idinga ukwenziwa ngaphansi kwezinga lokushisa elifanele kanye nezimo ukuze kuqinisekiswe isivuno esiphezulu nokuhlanzeka.

Ulwazi Lokuphepha:
Ingokwezinhlanganisela eziphilayo futhi inobuthi obuthile. Ukunakekelwa kufanele kuthathwe ngesikhathi sokuphatha futhi kusetshenziswe ukugwema ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula. Ngesikhathi esifanayo, ukuvimbela ukuthintana kwayo nezinto ezivuthayo kanye nama-oxidants, futhi igcinwe kahle. Lapho usebenza, kunconywa ukuthi ukwenze endaweni enomoya omuhle futhi efakwe izinto zokuzivikela ezifanele. Uma uthintana ngephutha noma uhogele umoya, geza ngokushesha futhi ufune usizo lwezokwelapha. Ukuqinisekisa ukuphepha, sicela ubheke imihlahlandlela yokusebenza kwezokuphepha efanele kanye nemithethonqubo.
