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

Isingeniso

I-Methyl 1,2,3-triazole-4-carboxylic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

Ikhwalithi:

I-Methyl 1,2,3-triazole-4-carboxylic acid iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elimnandi elinamandla. Incibilika kuma-organic solvents njenge-ethanol ne-dimethylformamide. Iyazinzile ekamelweni lokushisa, kodwa ibola emazingeni okushisa aphezulu noma ngaphansi kokukhanya.

Ukusetshenziswa: Ingasetshenziswa futhi njengesilawuli sokukhula kwesitshalo kanye nengxenye yezinto ezithinta izithombe.

Indlela:

Indlela evamile yokulungiselela i-methyl 1,2,3-triazole-4-carboxylic acid itholakala ngokusabela nge-phenylenediamine kanye ne-formic anhydride ngaphansi kwezimo ze-alkaline. Inqubo ethize yokulungiselela imi kanje:

I-1) Engeza i-phenylenediamine ne-anhydride ye-formic kusisombululo se-alkaline, ngokuvamile usebenzisa i-sodium hydroxide noma i-sodium carbonate njenge-alkaline agent;

I-2) Ekushiseni okufanelekile, ukusabela kwenziwa amahora amaningana ukwenza ama-reactants asabele ngokugcwele;

3) Umkhiqizo uyahlungwa futhi uhlanjululwe nge-distillation ukuze uthole i-methyl 1,2,3-triazole-4-carboxylate.

Ulwazi Lokuphepha:

I-Methyl 1,2,3-triazole-4-carboxylic acid iyacasula kakhulu futhi iyagqwala, futhi ukuthintana nesikhumba, amehlo, noma ukuhogela umhwamuko wayo kungabangela ukucasuka noma ezinye izinkinga zempilo. Izisetshenziswa zokuzivikela ezifanelekile (i-PPE), okuhlanganisa amagilavu, izingubo zamehlo ezivikelayo, nezinto zokuzivikela eziphefumulayo, kufanele zigqokwe lapho zisetshenziswa noma ziphathwa. Kufanele isetshenziswe endaweni enomoya omuhle futhi igweme ukuthintana nama-oxidizing agents aqinile noma izinto ezivuthayo. Uma uthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha.
