Selelekela
Tetramethylguanidine, eo hape e tsejoang e le N,N-dimethylformamide, ke kristale e tiileng e se nang 'mala. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea tetramethylguanidine:
Boleng:
- Tetramethylguanidine e na le alkaline e matla 'me e ka etsa tharollo e matla ea alkaline ka tharollo ea metsi.
- Ke motheo o fokolang o lekanang le tharollo ea anhydrous, 'me e ka sebelisoa e le moamoheli oa li-ion tsa hydrogen.
- E tiile mochesong oa kamore, empa e ka fetoha ka potlako ho ba khase e se nang mebala ha e futhumala.
- Ke motsoako o nang le hygroscopicity e matla.
Sebelisa:
- Tetramethylguanidine e sebelisoa haholo-holo e le mohloli oa alkali ho liphetoho tsa organic synthesis.
- E ka boela ea sebelisoa liindastering tse kang dae intermediates, electroplating, flexible polyurethane foams, joalo-joalo.
Mokhoa:
- Tetramethylguanidine e ka lokisoa ke karabelo ea N,N-dimethylformamide ka khase ea ammonia ka khatello e phahameng.
- Hangata mokhoa ona o hloka ho futhumatsa 'me o etsoa tlas'a tšireletso ea khase ea inert.
Lintlha tsa Tšireletseho:
- Tetramethylguanidine ke motsoako o chefo 'me o lokela ho qojoa ha o kopana le letlalo le mahlo. Apara liatlana tse sireletsang le likhalase ha u sebelisa.
- E ka baka ho teneha ha mahlo le letlalo, 'me ea baka bothata ba ho hema le matšoao a chefo.
- Tlhokomelo e lokela ho nkoa ho qoba ho kopana le li-oxidants, li-acids le lintho tse tukang nakong ea tšebeliso le polokelo.
- Ha o sebetsana le tetramethylguanidine, mekhoa e nepahetseng ea ts'ebetso ea laboratori le mekhoa e sireletsehileng ea ho sebetsana le eona e lokela ho lateloa.
