I-2-Nitropropane (i-Dimethylnitromethane)

Ikhemikhaliniindawo

I-2-Nitropropane ekwaziwa ngokuba yi-dimethylnitromethane okanye i-isonitropropane lulwelo olungenambala, olunamafutha olunevumba elimnandi nelithambileyo. Luyatsha kwaye luyanyibilika emanzini. Luyanyibilika nakwizinto ezininzi eziphilayo ezinyibilikayo kuquka i-chloroform. Umphunga walo unokwenza umxube oqhumayo nomoya. Isetyenziswa njenge-cosolvent kwiipeyinti ukuphucula ukumanzisa kwepigment, iimpawu zokuhamba, kunye nokucutshungulwa kwe-electrostatic; ikwanciphisa ixesha lokomisa ipeyinti.

Izicelo

I-2-Nitropropane isetyenziswa kakhulu njengesinyibilikisi seekhompawundi ze-organic kunye neengubo; kunye nee-vinyl resins, iipeyinti ze-epoxy, i-nitrocellulose, kunye nerabha ekhlorini; kwii-inki zokuprinta, izincamathelisi, kunye nokuprinta njenge-inki ze-flexographic; ukugcinwa ngeempawu zendlela ezindleleni nakwiindlela ezinkulu; ukwakhiwa kweenqanawa; kunye nokugcinwa ngokubanzi. Ikwasetyenziswa kancinci njenge-remover yepeyinti kunye ne-varnish. I-2-Nitropropane ikwasetyenziswa njengesinyibilikisi kwimizi-mveliso yokucubungula ukutya ukuze kuhlulwe ioyile yemifuno egcwaliswe kancinci.
