2-Nitropropane (Dimethylnitromethane)

Tshuaj lom neegncov qauv

2-Nitropropane tseem hu ua dimethylnitromethane lossis isonitropropane yog cov kua roj tsis muaj xim, muaj ntxhiab tsw qab zib thiab mos. Nws yooj yim hlawv thiab yaj hauv dej. Nws kuj yaj tau hauv ntau cov kuab tshuaj organic suav nrog chloroform. Nws cov pa yuav tsim cov khoom sib xyaw nrog huab cua. Nws yog siv los ua cov tshuaj sib xyaw hauv cov xim pleev kom txhim kho cov xim ntub, cov khoom ntws, thiab kev ua electrostatic; nws kuj txo lub sijhawm ziab xim.

Cov ntawv thov

2-Nitropropane feem ntau yog siv ua cov kuab tshuaj rau cov organic compounds thiab coatings; nrog vinyl resins, epoxy paints, nitrocellulose, thiab chlorinated roj hmab; hauv cov number case luam ntawv, cov nplaum, thiab luam ntawv ua flexographic inks; kev saib xyuas nrog cov cim tsheb ntawm txoj kev thiab txoj kev loj; kev tsim nkoj; thiab kev saib xyuas dav dav.
