Isingeniso

I-Isopropylamine, eyaziwa nangokuthi i-dimethylethanolamine, iwuketshezi olungenambala olunephunga elimnandi. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-isopropylamine:

 

Ikhwalithi:

Izici ezingokomzimba: I-Isopropylamine iwuketshezi oluguquguqukayo, olungenambala ukuya kokuphuzi ngokukhanyayo ekamelweni lokushisa.

Izici zamakhemikhali: I-Isopropylamine iyi-alkaline futhi ingasabela nama-acids ukwenza usawoti. Igqwala kakhulu futhi ingagqwalisa izinsimbi.

 

Sebenzisa:

Izishintshi zemithamo: Ama-Isopropylamine angasetshenziswa njengezincibilikisi nezilawuli zokomisa kumapende nezingubo ukuze kuthuthukiswe ikhwalithi yemikhiqizo.

I-electrolyte yebhethri: ngenxa yezakhiwo zayo ze-alkaline, isopropylamine ingasetshenziswa njenge-electrolyte kwezinye izinhlobo zamabhethri.

 

Indlela:

I-Isopropylamine ivame ukulungiswa ngokungeza igesi ye-ammonia ku-isopropanol futhi ibhekane ne-catalytic hydration reaction at izinga lokushisa elifanele nokucindezela.

 

Ulwazi Lokuphepha:

I-Isopropylamine inephunga elimnandi futhi kufanele isetshenziswe ngokunaka umoya kanye nezinyathelo zokuzivikela zokugwema ukuhogela ngokuqondile noma ukuthintana nesikhumba namehlo.

I-Isopropylamine iyagqwala futhi kufanele ivinjwe ukuthi ingathintani nesikhumba, amehlo kanye nolwelwesi lwamafinyila, futhi uma kuthintwa, kufanele ihashazwe ngokushesha ngamanzi amaningi futhi kufunwe ukunakekelwa kwezempilo ngokushesha.

Lapho ugcina, isopropylamine kufanele igcinwe endaweni eyomile, epholile, enomoya omuhle, kude nemithombo yomlilo nama-oxidants.
