Malo otentha a acetonitrile: gawo lofunikira pamakampani opanga mankhwala
Acetonitrile, monga chosungunulira chofunikira kwambiri pamakampani opanga mankhwala, amagwiritsidwa ntchito kwambiri popanga mankhwala, mankhwala abwino komanso kusanthula kwamadzi achromatography. Kudziwa magawo akuthupi a Acetonitrile ndikofunikira kuti igwiritsidwe ntchito pamakampani, pomwe kuwira ndi chimodzi mwazinthu zofunika kwambiri. Mu pepala ili, kutentha kwa acetonitrile kudzawunikidwa mwatsatanetsatane, ndipo mphamvu ya chizindikiro ichi pa ntchito ya mankhwala idzakambidwa.
Malo otentha a acetonitrile ndi zomwe zimachititsa
Kuwira kwa acetonitrile nthawi zambiri kumakhala 81.6 ° C (pafupifupi 179 ° F), ndipo kutentha kumeneku kumakhala kofunikira kwambiri pa distillation, rectification ndi njira zina zolekanitsa muzinthu za mankhwala. Kuwira kwa acetonitrile kumakhudzidwa ndi zinthu zambiri, kuphatikizapo kupanikizika, chiyero, ndi kusakanikirana ndi zinthu zina. Kawirikawiri, kutentha kwa acetonitrile kumakhala kokhazikika pansi pa kupanikizika kwa mumlengalenga, koma ngati kupanikizika kumasintha, malo otentha adzasinthanso. Mwachitsanzo, pansi pa kupanikizika kochepa, kutentha kwa acetonitrile kumachepa, ndipo mosiyana, pansi pazifukwa zopanikizika, kutentha kumawonjezeka. Chikhalidwe ichi chimapangitsa acetonitrile kukhala ndi mwayi wochulukirapo wogwiritsa ntchito pazinthu zosiyanasiyana.
Kufunika kwa malo otentha a acetonitrile pamafakitale
Kudziwa kuwira kwa acetonitrile ndikofunika kwambiri popanga momwe mankhwala amagwirira ntchito. Popanga mafakitale, nthawi zambiri pamafunika kupatutsa zosakaniza, ndipo kuwira kwa acetonitrile kumapangitsa kuti ikhale imodzi mwazinthu zabwino kwambiri pakubwezeretsa zosungunulira. Mwachitsanzo, pakuwunika kwa chromatography yamadzimadzi, nsonga yoyenera yowira ya acetonitrile imapangitsa kuti isungunuke pakatentha pang'ono, kupewa kuwonongeka kwachitsanzocho. Mu chemistry yopangira, kuwongolera kutentha komwe kumayendera pafupi kapena pansi pa nsonga yowira ya acetonitrile kumathandiza kuonetsetsa chitetezo cha zomwe zimachitika komanso kuyera kwa zinthuzo.
Momwe mungagwiritsire ntchito nsonga yowira ya acetonitrile kukhathamiritsa kupanga
Podziwa ndikumvetsetsa kuwira kwa acetonitrile, mainjiniya amatha kukhathamiritsa njira zopangira kuti azitha kuyendetsa bwino komanso kuchepetsa ndalama. Mwachitsanzo, mu njira ya distillation, nsonga yowira ya acetonitrile ingagwiritsidwe ntchito ngati maziko ofunikira poyika kutentha kwa ntchito ya distillation column kuti zitsimikizidwe kuti pali kusiyana koyenera. Posintha kukakamiza kwa dongosolo kuti musinthe malo otentha a acetonitrile, ndizotheka kukwaniritsa ntchito zosinthika zosinthika pamikhalidwe yosiyanasiyana. Njirayi siingangopulumutsa mphamvu moyenera, komanso imapangitsanso chitetezo ndi kukhazikika kwa mzere wonse wopanga.
Chidule
Kuwira kwa acetonitrile ndi gawo lofunika kwambiri pamakampani opanga mankhwala, lomwe limakhudza mwachindunji kupanga ndi kukhazikitsa ntchito zosiyanasiyana zama mankhwala. Kuyambira kuzinthu zoyambira za acetonitrile, kumvetsetsa mozama za zinthu zomwe zimakhudzidwa ndi kuwira kwake komanso ntchito yake m'mafakitale kungathandize mainjiniya kukhathamiritsa bwino ntchito yopanga, kupititsa patsogolo mtundu wazinthu ndikukwaniritsa cholinga cha chitukuko chokhazikika. Pomvetsetsa bwino ndikugwiritsa ntchito nsonga yowira ya acetonitrile, makampani opanga mankhwala amatha kutenga mwayi pampikisano wowopsa wamsika.
