Selelekela
Methyl 1,2,3-triazole-4-carboxylic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
Methyl 1,2,3-triazole-4-carboxylic acid ke seela se se nang mmala ho isa ho sesehla se bobebe se nang le monko o matla o hlabang. E qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide. E batla e tsitsitse mocheso oa kamore, empa e senyeha ka mocheso o phahameng kapa tlas'a khanya.
Tšebeliso: E ka boela ea sebelisoa e le molaoli oa kholo ea limela le karolo ea thepa e bonang lifoto.
Mokhoa:
Mokhoa o tloaelehileng oa ho itokisa bakeng sa methyl 1,2,3-triazole-4-carboxylic acid e fumanoa ka ho itšoara ka phenylenediamine le formic anhydride tlas'a maemo a alkaline. Mokhoa o khethehileng oa ho itokisa ke o latelang:
1) Eketsa phenylenediamine le formic anhydride ho tharollo ea alkaline, hangata e sebelisa sodium hydroxide kapa sodium carbonate e le moemeli oa alkaline;
2) Ka mocheso o loketseng, karabelo e etsoa lihora tse 'maloa ho etsa hore li-reactants li arabele ka botlalo;
3) Sehlahisoa se hloekisoa le ho hloekisoa ka distillation ho fumana methyl 1,2,3-triazole-4-carboxylate.
Lintlha tsa Tšireletseho:
Methyl 1,2,3-triazole-4-carboxylic acid e halefisa haholo ebile e senya, 'me ho kopana le letlalo, mahlo, kapa ho hema mouoane oa eona ho ka baka ho teneha kapa mathata a mang a bophelo. Thepa e nepahetseng ea ts'ireletso ea motho (PPE), ho kenyeletsoa liatlana, liaparo tse sireletsang mahlo, le lisebelisoa tsa ts'ireletso ea ho hema, li lokela ho apesoa ha li sebelisoa kapa li tšoaroa. E lokela ho sebetsoa sebakeng se nang le moea o motle 'me u qobe ho kopana le li-oxidizing tse matla kapa lisebelisoa tse tukang. Haeba motho a ka kopana ka phoso, hlatsoa hang-hang ka metsi a mangata 'me u batle thuso ea bongaka hang-hang.
