Intshayelelo
I-1-Methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid, eyaziwa ngokuba yi-Methyl 6-oxo-1,6-dihydropyridine-3-carboxylate, efinyeziweyo njenge-MOM-PyCO2H. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
I-MOM-PyCO2H yi-organic compound ene-crystalline emhlophe ukuya kwi-yellow yellowline okanye i-crystalline powder.
Sebenzisa:
I-MOM-PyCO2H isetyenziswa ngokubanzi kwi-organic synthesis chemistry kwaye isetyenziswa kakhulu njengendawo ephakathi kwi-organic synthesis. Inokuthi ifakwe kwii-molecule ze-organic njengeqela elibalulekileyo elisebenzayo, ngaloo ndlela iguqula iipropati kunye nomsebenzi we-molecule.
Indlela:
Ukulungiswa kwe-MOM-PyCO2H ngokuqhelekileyo kufezekiswa ngokuphendula kweekhemikhali. Indlela eqhelekileyo kukusabela i-sodium cyanide kunye ne-methyl carbonate ukuvelisa i-1-methyl-6-oxo-1,6-dihydropyridin-3-formylhydrazide, ethi ke i-oxidized kwimveliso ekujoliswe kuyo i-MOM-PyCO2H.
Ulwazi ngoKhuseleko:
UMAMA-PyCO2H ukhuselekile, kodwa njenge-agent yekhemikhali, kuseyingozi. Iinkqubo zokusebenza eziyimfuneko zokhuseleko kufuneka zilandelwe ngexesha lokusetyenziswa. Ukudibana okanye ukuphefumla iziyobisi kunokubangela ukucaphuka, kwaye ukudibana ngqo nolusu, amehlo, njl.njl. kufuneka kuphetshwe kangangoko kunokwenzeka. Xa zisetyenziswa kwindawo yaselabhoratri, izixhobo ezifanelekileyo zokuzikhusela ezinjengeeglavu neeglasi zifanele zinxitywe. Kufuneka kwakhona igcinwe kwindawo epholileyo, eyomileyo nengena umoya kakuhle, kude nemithombo yomlilo kunye nezinto ezinokutsha. Xa kwenzeka ingozi, kufuneka ngokukhawuleza uthathe amanyathelo angxamisekileyo afanelekileyo kwaye udibane nochwepheshe.
