Malo owiritsa a Acetunitrile: Kusanthula kwa malo ofunikira ndi mafakitale
Acetunitrile ndi gawo lodziwika bwino lomwe lili ndi formula ch₃cn.as sololation, acetonitrile limagwiritsidwa ntchito kwambiri mu mankhwala, mankhwala opangira mankhwala, komanso mafakitale. Kumvetsetsa zinthu zakuthupi za acetonitrile, makamaka zowira za acetonitrile, ndizofunikira kwambiri pakugwiritsa ntchito kwake. Mu pepala ili, owiritsa owira a Acetunitrile ndi tanthauzo lake m'mafakitale adzafotokozedwa mozama.
Katundu woyambira ndi malo otentha a acetonitrile
Acetunitrile ndi madzi opanda utoto komanso owoneka bwino okhala ndi polarity yayikulu, motero imatha kusungunula mankhwala a polar komanso osakhala polar. Acetunitrile ali ndi malo otentha a 81.6 ° C, kutentha komwe ndikofunikira pakugwiritsa ntchito mankhwala. Kuwiritsa kotsika kwa acetonitrile kumapangitsa kuti ndikosavuta kusinthira kutentha ndi kupanikizika, kupangitsa kukhala koyenera kwa njira zingapo zomwe zimafunikira kuyanika kapena kusinthika.
Kufunika kwa malo owiritsa owira mu mapulogalamu osungunulira
Acetunitrile imagwiritsidwa ntchito kwambiri ngati somomatographic kusanthula kwa chplutography fromatography (HPLC). Ku HPLC, owira malo osungunulira amakhudzanso kusankha kwa gawo lam'manja ndi kusintha kwapakati. Chifukwa cha kuwira kochepa kwa acetonitrile, imatha kutulutsidwa mwachangu, kuchepetsa malo otsalira ndikuwongolera chiwanda. Kugwiritsa ntchito acetonitrile mu kapangidwe ka mankhwala kumadalira mawonekedwe ake owotcha. Mwachitsanzo, popanga zikhalidwe zina pomwe kutentha kumayenera kuwongoleredwa, malo otentha a acetonitrile angagwiritsidwe ntchito pofotokoza zomwe zimachitika.
Kuwongolera kuwongolera kwa acetonitrile mu mafakitale
Mukupanga ndi kusungirako kwa acetonitrile, kuwongolera kwa malo otentha a acetonitrile ndikofunikira. Popeza kuti acetonitrile ili ndi kusasinthika kwakukulu kumafunikira panthawi yopanga njira yopangira magazi kwambiri, komwe kungakhudze zokolola ndi zabwino. Mukamasunga acetonitrile, nthawi zambiri amafunika kukhala otsika kutentha kapena malo osindikizidwa kuti achepetse kuwonongeka kwa acetonitrile ndikuwonetsetsa kuti ndi chitetezo.
Chitetezo ndi Chilengedwe cha Maganizo a Acetunitrile
Kusuta kwa acetonitrile kumapangitsa kuwira kwake kofunikira mu chitetezo cha chitetezo ndi chilengedwe. Mukamagwira ntchito ndikugwiritsa ntchito acetonitrile, kukhazikika kwake kuyenera kuonedwa kuti kumalepheretse kupuma kwakukulu kwa mpweya wa acetonitrile. Kudziwa malo owiritsa a acetonitrile kumatha kukuthandizani kupanga chogwiritsira ntchito mankhwala osokoneza bongo.
Chidule
Kudziwa malo otentha a acetonitrile ndikofunikira pakugwiritsa ntchito kwake kwa mafakitale. Kaya mukupanga, kusungirako kapena kugwiritsa ntchito, malo owiritsa a acetonitrile kumakhudza chitetezo, kuchita bwino ndi chilengedwe. Chifukwa chake, mu makampani azachipatala, kupenyerera ku malo owiritsa a acetonitrile ndi amodzi mwa makiyi kuti awonetsetse njira zosalala.
