Intshayelelo

I-Methyl 1,2,3-triazole-4-carboxylic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

 

Umgangatho:

I-Methyl 1,2,3-triazole-4-carboxylic acid lulwelo olungenambala ukuya kumthubi olukhanyayo kunye nevumba elibukhali elibukhali. Iyanyibilika kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide. Izinzile kwiqondo lokushisa, kodwa ibolile kumaqondo aphezulu okanye phantsi kokukhanya.

 

Usetyenziso: Isenokusetyenziswa njengolawulo lokukhula kwezityalo kunye nenxalenye yemathiriyeli ye-photosensitive.

 

Indlela:

Indlela eqhelekileyo yokulungiselela i-methyl 1,2,3-triazole-4-carboxylic acid ifunyenwe ngokuphendula nge-phenylenediamine kunye ne-anhydride efomini phantsi kweemeko ze-alkaline. Inkqubo yolungiselelo ethile imi ngolu hlobo lulandelayo:

I-1) Yongeza i-phenylenediamine kunye ne-anhydride ye-formic kwisisombululo se-alkaline, ngokuqhelekileyo usebenzisa i-sodium hydroxide okanye i-sodium carbonate njenge-alkaline agent;

2) Kwiqondo lokushisa elifanelekileyo, ukusabela kuqhutyelwa iiyure eziliqela ukwenza i-reactants iphendule ngokupheleleyo;

3) Imveliso iyahluzwa kwaye ihlanjululwe nge-distillation ukufumana i-methyl 1,2,3-triazole-4-carboxylate.

 

Ulwazi ngoKhuseleko:

I-Methyl 1,2,3-triazole-4-carboxylic acid iyacaphukisa kakhulu kwaye inobungozi, kwaye ukudibana nolusu, amehlo, okanye ukuphefumla umphunga wayo kunokubangela ukucaphuka okanye ezinye iingxaki zempilo. Izixhobo ezifanelekileyo zokuzikhusela (PPE), kubandakanywa iiglavu, izambatho zamehlo ezikhuselayo, kunye nezixhobo zokukhusela zokuphefumla, kufuneka zinxitywe xa zisetyenziswa okanye ziphathwa. Kufuneka iqhutywe kwindawo enomoya kwaye ugweme ukudibanisa kunye ne-oxidizing agents ezinamandla okanye izinto ezinokutsha. Kwimeko yokudibana ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
