Kev siv
Nyob rau hauv cov nqe lus ntawm nws cov tshuaj synthesis, propionaldehyde yog tau los ntawm oxo-synthesis ntawm ethylene ua raws li los ntawm kev txo. Cov txheej txheem no ua kom cov purity thiab cov qauv zoo ntawm n-propanol, ua rau nws haum rau ntau yam kev siv.
Ib qho ntawm cov kev siv tseem ceeb ntawm n-propanol yog nyob rau hauv cov organic synthesis. Nws yog ib qho tseem ceeb ntawm kev lag luam kws tshuaj thiab siv rau hauv cov tshuaj sib xyaw xws li probenecid, sodium valproate, erythromycin, tshuaj qaug dab peg, hemostatic thaj ua rau thaj BCA, thiamine, 2,5-dipropylpicolinic acid, thiab n- ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. ntawm Propylamine. Cov tebchaw no tau ua rau muaj txiaj ntsig zoo rau kev nce qib ntawm kev kho mob thiab ua rau kev txhim kho kev noj qab haus huv.
Tsis tas li ntawd, n-propanol kuj tseem siv tau los ua cov tshuaj analytical reagent. Nws cov khoom tshwj xeeb thiab purity siab ua rau nws yog ib qho cuab yeej txhim khu kev qha rau ntau yam kev soj ntsuam hauv chav kuaj, ua rau muaj qhov tseeb thiab meej. Cov kws tshawb fawb thiab cov kws tshawb fawb vam khom rau qhov sib xws thiab kev ua tau zoo ntawm n-propanol hauv lawv cov kev tshawb fawb soj ntsuam, kom ntseeg tau tias muaj txiaj ntsig zoo thiab rov tsim dua tshiab.
Lwm qhov tseem ceeb ntawm daim ntawv thov ntawm n-propanol yog nws lub peev xwm los ua kom kub kub. Los ntawm kev sib xyaw cov khoom sib xyaw ua ke no nrog alkanes thiab alkenes, nws muaj peev xwm ua kom qhov kub thiab txias nce ntxiv. Cov yam ntxwv no ua rau nws muaj kev xaiv zoo tshaj plaws rau kev sib xyaw roj, ua kom muaj kev sib xyaw ua kom zoo dua qub thiab txhawb cov khoom siv hluav taws xob huv.
Hauv kev xaus, n-propanol yog ib qho tseem ceeb thiab tseem ceeb hauv kev lag luam sib txawv vim nws cov khoom muaj txiaj ntsig zoo thiab ntau yam. Kev lag luam kws tshuaj siv nws lub peev xwm rau kev sib txuas ntawm cov tshuaj tseem ceeb, thaum lub chaw soj nstuam tso siab rau nws txoj kev ntseeg tau raws li kev tshuaj ntsuam xyuas. Tsis tas li ntawd, n-propanol plays lub luag haujlwm hauv kev ua kom kub hnyiab, ua rau nws yog ib qho tseem ceeb ntawm cov roj sib xyaw. Ua tus thawj coj ua lag luam hauv kev tsim khoom thiab muab khoom ntawm n-Propanol, peb lub tuam txhab ua kom cov qauv zoo tshaj plaws, muab cov kev daws teeb meem txhim khu kev qha rau koj cov kev xav tau tshwj xeeb.
