Folasaga

Azodicarboxamide (N,N'-dimethyl-N,N'-dinitrosoglylamide) o se faʻamaʻi tioata e leai ni lanu ma ni mea faʻapitoa ma ni faʻaoga eseese.

 

Tulaga lelei:

O le Azodicarboxamide o se tioata e leai ni lanu i le vevela o le potu, e mafai ona solu i acids, alkalis ma solu faʻalaʻau, ma e lelei le solubility.

E a'afia i le vevela pe feula ma pa, ma ua fa'avasegaina o mea pa.

O le Azodicarboxamide o lo'o i ai ni mea fa'ama'i malosi ma e mafai ona fa'aoso fa'amalosi i mea fa'amumu ma faigofie ona fa'ama'iina.

 

Fa'aaogā:

O le Azodicarboxamide o loʻo faʻaaogaina lautele i le vaega o vailaʻau faʻapipiʻi ma o se mea taua tele ma le vaeluagalemu i le tele o gaioiga faʻasolosolo.

O lo'o fa'aaogaina e fai ma mea mata mo le fa'alanu pigments i totonu o pisinisi vali.

 

Metotia:

O auala sauniuni ole azodicarbonamide e masani lava e faʻapea:

E faia i le tali atu o le nitrous acid ma le dimethylurea.

E gaosia e ala ile tali ole soluble dimethylurea ma le dimethylurea na amataina e le nitric acid.

 

Fa'amatalaga Saogalemu:

O le Azodicarboxamide e sili ona pa ma e tatau ona taofia mai le mumu, feteʻenaʻiga, vevela ma isi mea e mu.

O totigilima puipui talafeagai, mata tioata, ma matapulepule e tatau ona ofuina pe a faʻaaoga le azodicarbonamide.

Aloese mai le fa'afeso'ota'i ma vaila'au fa'ama'i ma mea fa'amumu i le taimi o le taotoga.

O le Azodicarbonamide e tatau ona teuina i totonu o se nofoaga faʻamaufaʻailoga, malulu, faʻalelei lelei mai le susulu o le la.
