Folasaga

Tetramethylguanidine, e lauiloa foi o le N, N-dimethylformamide, o se tioata tioata lanu. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le tetramethylguanidine:

 

Tulaga lelei:

- Tetramethylguanidine e malosi alkaline ma e mafai ona fausia se vaifofo malosi alkaline i vai vai.

- O se faʻavae vaivai e tutusa ma se vaifofo anhydrous, ma e mafai ona faʻaaogaina e avea o se tagata e mauaina ion hydrogen.

- E malo i le vevela o le potu, ae mafai ona vave fa'afefe i se kasa e leai ni lanu pe a vevela.

- O se fa'afefiloi ma le malosi hygroscopicity.

 

Fa'aaogā:

- Tetramethylguanidine e masani ona faʻaaogaina e avea o se faʻamaʻi alkali i gaioiga faʻasolosolo faʻasolosolo.

- E mafai foʻi ona faʻaaogaina i alamanuia e pei o le vali vali, faʻapipiʻi eletise, faʻafefete polyurethane foam, ma isi.

 

Metotia:

- Tetramethylguanidine e mafai ona saunia e ala ile tali ole N,N-dimethylformamide faʻatasi ma le ammonia gas ile maualuga maualuga.

- O lenei faiga e masani ona manaʻomia le faʻamafanafanaina ma e faia i lalo o le puipuiga o se kesi lemu.

 

Fa'amatalaga Saogalemu:

- Tetramethylguanidine ose vaila'au oona ma e tatau ona 'alo'ese pe a fa'afeso'ota'i ma le pa'u ma mata. Fai totigilima ma mata tioata pe a fa'aaoga.

- E mafai ona afaina ai mata ma le pa'u, ma fa'alavelave ai le manava ma fa'ailoga oona.

- E tatau ona fa'aeteete ina ia 'alofia le fa'afeso'ota'i ma vaila'au fa'ama'i, vaila'au ma mea e mu a'o fa'aoga ma teuina.

- Pe a tagofia le tetramethylguanidine, e tatau ona mulimulitaʻia faiga faʻaoga tatau fale suʻesuʻe ma faʻatonuga saogalemu.
