Intshayelelo
Indalo:
I-3-Amino-2-fluoropyridine yikristale emhlophe eqinile kunye neempawu zempawu ze-pyridine compounds. Iphantse inganyibiliki emanzini kubushushu obuqhelekileyo, kodwa inyibilika kwii-solvents eziphilayo ezifana ne-alcohol, i-ethers, i-ketones kunye ne-esters. Inokuguquka okuphakathi kunye nevumba elibukhali elibukhali.
Sebenzisa:
I-3-Amino-2-fluoropyridine isetyenziswa ngokubanzi kwiinkalo zonyango, i-pesticide kunye neshishini lemichiza. Yinto ebalulekileyo ephakathi kuphuhliso kunye nokuveliswa kwezinto ezininzi zebhayoloji ezisebenzayo, ezifana namayeza kunye nezitshabalalisi. Kwintsimi yeyeza, isetyenziswa rhoqo kwi-synthesis ye-antibiotics, i-antiviral drug, i-cardiovascular and cerebrovascular drug. Kwintsimi ye-pesticides, inokusetyenziswa njengenxalenye ebalulekileyo ye-insecticide, i-herbicides kunye nee-agent zokulawula ukhula. Ukongezelela, ngenxa yokuzinza kweekhemikhali, i-3-Amino-2-fluoropyridine ingasetyenziselwa njenge-catalyst kunye ne-solvent ye-organic synthesis reactions.
Indlela:
Ngokuqhelekileyo, indlela yokulungiselela i-3-Amino-2-fluoropyridine iquka ukuthatha i-chloroacetic acid kunye ne-2-amino sodium fluoride njengezinto ezibonakalayo, kunye nokuphendula ukuvelisa i-3-Amino-2-fluoropyridine. Indlela ethile yokulungiselela iyahluka ngokuxhomekeka kwiimeko kunye nomlinganiselo osetyenzisiweyo.
Ulwazi ngoKhuseleko:
I-3-Amino-2-fluoropyridine kufuneka ihlawule ingqalelo kumanyathelo okhuseleko ngexesha lokusetyenziswa kunye nokugcinwa. Iyacaphukisa kwaye kufuneka igweme ukuphefumla iigesi, uthuli okanye umphunga kwaye udibane nolusu, amehlo kunye nenwebu. Nxiba iiglavu zokukhusela, izibuko kunye nempahla efanelekileyo yokukhusela ngexesha lokusebenza. Kwimeko yokuphefumla ngengozi okanye ukudibana ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango. Ukongeza, kufuneka igcinwe kwindawo epholileyo, eyomileyo, engenamoya ngexesha lokugcinwa, kude nomlilo kunye ne-oxidants.
