2-Nitropropane (Dimethylnitromethane)

Amakhemikhalinama-atures

I-2-Nitropropane eyaziwa nangokuthi i-dimethylnitromethane noma i-isonitropropane iwuketshezi olungenambala, olunamafutha olunephunga elipholile nelimnandi.Iyavutha futhi inyibilika emanzini.Iphinde inyibilike kuzincibilikisi eziningi eziphilayo ezihlanganisa i-chloroform.Umhwamuko wawo ungase wakhe ingxube eqhumayo nomoya.Isetshenziswa njenge-cosolvent kumapende ukuthuthukisa ukumanzisa kwe-pigment, izakhiwo zokugeleza, nokucutshungulwa kwe-electrostatic;futhi kunciphisa isikhathi sokumisa upende.

Izinhlelo zokusebenza

I-2-Nitropropane isetshenziswa ngokuyinhloko njenge-solvent ye-organic compounds kanye nezingubo;nge-vinyl resins, opende be-epoxy, i-nitrocellulose, nerabha ene-chlorinated;ekunyatheliseni oyinki, izinto zokunamathisela, nokunyathelisa njengoyinki we-flexographic;ukugcinwa kwezimpawu zethrafikhi emigwaqweni nasemigwaqweni emikhulu;ukwakhiwa kwemikhumbi;kanye nokugcinwa okuvamile.Iphinde ibe nokusetshenziswa okulinganiselwe njengesikhiphi sikapende ne-varnish.I-2-Nitropropane iphinde isetshenziswe njengesixazululi ezimbonini ezilungisa ukudla ukuze kuhlukaniswe amafutha emifino agcwele ingxenye.
