methyl 2H-1 2 3-triazole-4-carboxylate (CAS # 4967-77-5)
Taw qhia
Methyl 1,2,3-triazole-4-carboxylic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Methyl 1,2,3-triazole-4-carboxylic acid yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw muaj zog. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethylformamide. Nws yog qhov ruaj khov ntawm chav tsev kub, tab sis decomposes ntawm qhov kub thiab txias los yog hauv qab lub teeb.
Kev Siv: Nws kuj tseem siv tau los ua cov nroj tsuag kev loj hlob regulator thiab ib feem ntawm cov ntaub ntawv photosensitive.
Txoj kev:
Ib txoj kev npaj rau methyl 1,2,3-triazole-4-carboxylic acid yog tau los ntawm reacting nrog phenylenediamine thiab formic anhydride nyob rau hauv alkaline tej yam kev mob. Cov txheej txheem npaj tshwj xeeb yog raws li hauv qab no:
1) Ntxiv phenylenediamine thiab formic anhydride rau cov tshuaj alkaline, feem ntau yog siv sodium hydroxide lossis sodium carbonate ua tus neeg sawv cev alkaline;
2) Ntawm qhov ntsuas kub uas tsim nyog, cov tshuaj tiv thaiv tau ua rau ob peb xuab moos kom cov reactants ua kom muaj zog;
3) Cov khoom yog lim thiab lim los ntawm distillation kom tau methyl 1,2,3-triazole-4-carboxylate.
Cov ntaub ntawv kev nyab xeeb:
Methyl 1,2,3-triazole-4-carboxylic acid yog heev khaus thiab corrosive, thiab kev sib cuag nrog daim tawv nqaij, qhov muag, los yog nqus tau pa ntawm nws vapors yuav ua rau khaus lossis lwm yam teeb meem kev noj qab haus huv. Cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog hnab looj tes, looj tsom iav, thiab cov khoom tiv thaiv ua pa, yuav tsum hnav thaum siv lossis tuav. Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob sib cuag nrog cov muaj zog oxidizing neeg sawv cev los yog cov ntaub ntawv flammable. Yog tias muaj kev sib cuag tsis raug, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob sai.
