Intshayelelo
I-2-Chloro-6-methyl-5-nitropyridine yinto eqhelekileyo yezinto eziphilayo,
Umgangatho:
- Ukubonakala: I-2-chloro-6-methyl-5-nitropyridine i-crystalline eqinile engenambala okanye ephuzi.
- Ukunyibilika: Inyibilika ngokulula kwizinyibilikisi ze-organic ezifana ne-ethanol, i-dimethylformamide kunye ne-chloroform.
Sebenzisa:
- Iidayi: Le khompawundi ingasetyenziselwa ukudibanisa ezinye iidayi zamashishini, ezifana nesakhiwo sinepropati yokufunxa ukukhanya kwe-UV, kwaye isetyenziswa ngokubanzi kwi-pigment kunye neshishini ledayi.
Indlela:
I-2-Chloro-6-methyl-5-nitropyridine inokufumaneka nge-chlorination kunye ne-nitrification ye-pyridine. Indlela ekhethekileyo yokulungiselela inokuba kukusebenzisa i-nitric acid kunye ne-asidi ye-sulfuric ukusabela ekufumaneni i-nitrite acid, i-nitrite iphendule i-nitrite kunye ne-nitrate yobhedu ukwenza i-nitrate yobhedu, kwaye emva koko isebenzise i-electrophilic methylation reagents (efana ne-methyl halogen) ukusabela nge-nitrate yobhedu ukufumana i-nitrate yobhedu. imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
I-2-Chloro-6-methyl-5-nitropyridine i-compound enetyhefu enomsindo kwaye iyingozi. Xa usebenzisa kwaye uphatha, izilumkiso ezifanelekileyo ezinjengokunxiba iliso elikhuselayo, iiglavu kunye nempahla ekhuselayo iyafuneka. Kuphephe ukuphefumla umphunga okanye uthuli lwayo, kwaye kuphephe ukudibana nolusu namehlo. Xa usebenzisa le ngqungquthela, kufuneka kuthathelwe ingqalelo ukuzinza kwayo kwaye ugweme ukudibanisa nezinye iikhemikhali ezingahambelaniyo. Xa ugcina, kufuneka ugcinwe kwisikhongozeli esingangeni moya, kude ne-ignition kunye ne-oxidants.
