2-Nitropropane (Dimethylnitromethane)

Mankhwalanziwalo

2-Nitropropane yomwe imadziwikanso kuti dimethylnitromethane kapena isonitropropane ndi madzi opanda mtundu, mafuta okhala ndi fungo lofewa komanso lokoma. Amayaka ndipo amasungunuka m'madzi. Amasungunukanso m'zinthu zambiri zachilengedwe kuphatikizapo chloroform. Nthunzi zake zimatha kupanga chisakanizo chophulika ndi mpweya. Imagwiritsidwa ntchito ngati cosolvent mu utoto kuti iwonjezere kunyowa kwa utoto, mphamvu zoyendera, komanso kukonza kwa electrostatic; imachepetsanso nthawi youma utoto.

Mapulogalamu

2-Nitropropane imagwiritsidwa ntchito makamaka ngati chosungunulira cha zinthu zachilengedwe ndi zokutira; ndi ma resins a vinyl, utoto wa epoxy, nitrocellulose, ndi rabara ya chlorine; posindikiza inki, zomatira, ndi kusindikiza ngati inki yosinthasintha; kukonza ndi zizindikiro za magalimoto m'misewu ndi misewu ikuluikulu; kumanga zombo; ndi kukonza zonse. Imagwiritsidwanso ntchito pang'ono ngati chochotsera utoto ndi varnish. 2-Nitropropane imagwiritsidwanso ntchito ngati chosungunulira m'mafakitale opangira chakudya kuti achepetse mafuta a masamba omwe ali ndi mafuta ochepa.

Zakuthupiform

Madzi opanda utoto, opaka mafuta okhala ndi fungo lofewa komanso la zipatso.
