methyl 2H-1 2 3-triazole-4-carboxylate（CAS# 4967-77-5)

Hoʻolauna

ʻO ka Methyl 1,2,3-triazole-4-carboxylic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:

ʻO ka Methyl 1,2,3-triazole-4-carboxylic acid he wai melemele māmā me ka ʻala ʻala ikaika. Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka dimethylformamide. Paʻa ia ma ka lumi wela, akā decompose i nā wela kiʻekiʻe a i ʻole ma lalo o ka mālamalama.

Hoʻohana: Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoponopono ulu a me kahi ʻāpana o nā mea photosensitive.

Hanana:

Loaʻa kahi ʻano hoʻomākaukau maʻamau no ka methyl 1,2,3-triazole-4-carboxylic acid ma ka hana ʻana me ka phenylenediamine a me ka anhydride formic ma lalo o nā kūlana alkaline. ʻO ke kaʻina hana hoʻomākaukau kūikawā penei:

1) Hoʻohui i ka phenylenediamine a me ka anhydride formic i kahi hopena alkaline, me ka hoʻohana pinepine ʻana i ka sodium hydroxide a i ʻole ka sodium carbonate ma ke ʻano he mea hana alkaline;

2) Ma kahi mahana kūpono, hoʻokō ʻia ka hopena no kekahi mau hola e hoʻokō pono ai nā reactants;

3) Hoʻopili ʻia ka huahana a hoʻomaʻemaʻe ʻia e ka distillation e loaʻa ai ka methyl 1,2,3-triazole-4-carboxylate.

ʻIke palekana:

ʻO ka Methyl 1,2,3-triazole-4-carboxylic acid he mea hoʻonāukiuki a ʻino, a ʻo ka pili ʻana me ka ʻili, nā maka, a i ʻole ka inhalation o kona mau mahu e hoʻoulu ai i nā pilikia olakino. Pono e ʻaʻahu ʻia nā lako pale pilikino (PPE), me nā mīkina lima, nā maka pale, a me nā mea pale hanu, ke hoʻohana ʻia a lawelawe ʻia paha. Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale aku i ka hoʻopili ʻana me nā mea oxidizing ikaika a i ʻole nā ​​​​mea puhi. Inā loaʻa ka pilikia, holoi koke me ka wai nui a ʻimi koke i ka lāʻau lapaʻau.
