Vim nws qhov taw tes qis, n-propanol raug cais raws li cov kua hluav taws xob. Nws yuav tsum tau khaws cia kom deb ntawm cov nplaim taws, cov nplaim taws, thiab qhov chaw kub, thiab ua haujlwm hauv qhov chaw zoo - qhov cua.
Cov Ntawv Thov Kev Lag Luam tseem ceeb
n-Propanol yog siv thoob plaws ntau qhov kev lag luam, feem ntau yog cov kuab tshuaj thiab ua tshuaj lom neeg nruab nrab:
Pharmaceutical thiab tshuaj tua kab intermediates: n-propanol yog siv nyob rau hauv cov organic synthesis los tsim intermediates rau tshuaj thiab agrochemicals.
Paints, inks, thiab coatings: nws dissolves nitro tshuaj tsuag xim, luam ntawv inks, thiab lwm yam formulations.
Tshuaj pleev ib ce thiab ntxuav cov khoom: nws tshwm nyob rau hauv cov tshuaj pleev ib ce, tshuaj ntxuav hniav dawb, tshuaj tua kab, thiab fungicides.
Kev sim thiab kev siv tshuaj ntsuam xyuas: n-propanol ua cov kuab tshuaj thiab chromatographic reagent hauv analytical chemistry.
Resins thiab polymers: nws tuaj yeem hloov tau qis dua - cov cawv cawv xws li ethanol hauv qee cov khoom siv hluavtaws thiab ua cov kuab tshuaj rau ethyl cellulose, polyvinyl butyral, zaub roj, thiab roj hmab ntuj.
Kev sib xyaw roj: n-propanol tuaj yeem sib xyaw nrog alkanes thiab alkenes ua cov roj sib tov los hloov cov cwj pwm sib xyaw.
