Acetonitrile: Nchintu chibotu chakusanzya alubo chibelesyo chakupanga zintu zipona
Zibeela Zipati Zyakubelesya
Mukulanga-langa kwamakemikalu, acetonitrile nchintu chibelesyegwa kapati mukulanga-langa zyintu zibeleka obotu (HPLC) antoomwe akulanga-langa muya (GC). Ilakonzya kunywika kabotu alimwi ilijisi busani buniini, ilakonzya kunywika kabotu zintu ziindene-indene zipona azitakwe buumi kutegwa zipe mpindu zisalala zyakuvwuntauzya. Acetonitrile alimwi ilabelesyegwa kubamba misamu iizumizyidwe alimwi amaanzi aakupima, ikusinizya kuti kulanga-langa kuli kabotu alimwi akusyomeka.
Mukupanga zintu zipona, acetonitrile nchintu chiyandikana loko mpawo nchintu chili akati-akati. ilakonzya kunyonyoona zintu zyiingi zipona, kupa busena butazungaani bwakuchitila kuswaangana kwamakemikalu. Mbuli chitondeezyo, mukupanga misamu imwi iili akati-akati alimwi azintu zipa tununkilizyo, acetonitrile ilakonzya kubeleka mbuli chintu chipa kuti kube kusanduka. Kuyungizya waawo, acetonitrile ilakonzya kutola lubazu muzintu zimwi zyamakemikalu kuti ipange misamu iijisi milimo imwi. Mbuli chitondeezyo, acetonitrile ilakonzya kwiinda mukusanduka kwa nucleophilic antoomwe a cyano group kuti ipange amine naa alcohol.
Mumakwebo aamisamu, acetonitrile ilabelesyegwa kapati mukupanga misamu akusalazya. ilakonzya kunyonyoona misamu isiyene-siyene iisaanguna amisamu iili akati-akati, ikugwasya kuti kube kusanduka kwamakemikalu. Mbuli chitondeezyo, mukupanga misamu imwi iilwana malwazi aamoyo, acetonitrile ilakonzya kubeleka mbuli chintu chiyungizya mweelwe wakusanduka akuzyala. Kuyungizya waawo, acetonitrile ilakonzya kubelesegwa kuchita kuti misamu ibe mbuli mabwe akusalazya kuchitila kuti misamu isalala akuba kabotu.
Mumakwebo aanunkilizyo azyakulisamika, acetonitrile ibelesyegwa mukupanga akusalazya tununkilizyo. ilakonzya kubelesegwa kugwisya tununkilizyo twachilengwaleza, mbuli mafuta mabotu kuzwa kuzisyango. Kuyungizya waawo, acetonitrile ilakonzya kubelesegwa kupanga tununkilizyo tujisi tununkilizyo tulibedelede twakupanga tununkilizyo atununkilizyo atununkilizyo.
Mumakwebo aamagesi, acetonitrile ibelesyegwa mbuli musamu wakusanzya akusanzya. ilakonzya kugwisya kabotu zintu zyakasyeede azintu zisofweede atala aazibelesyo zyamagesi, akusinizya kusalala akubeleka kabotu kwazibelesyo zyamagesi. Mbuli chitondeezyo, mukupanga ma semiconductor, acetonitrile ilakonzya kubelesegwa kusalazya atala aama wafers, kugwisya zintu zyakasyaala zya photoresist azintu zimwi zisofweede.
Nikuba kuti ilakonzya kubelesegwa munzila zyiingi, acetonitrile ilakonzya kuzungaana mpawo ilakola, mpawo kubelesya akubamba kwayo kuyandika nzila zyakukwabilila. Acetonitrile ilafwambaana kubola mumuwo, aboobo yeelede kubelesegwa mubusena bujisi muuya mubotu. Kuyungizya waawo, misamu ya acetonitrile ilakonzya kuba abuti, mpawo zibelesyo zyakulikwabilila zyeelede kuzwalwa muchiindi chakubelesya kuchitila kuti utajatikizyi chikumba ameso. Mukupanga zintu mumafakitali, kubelesya acetonitrile kanjikanji kuchitwa mumasena aajalidwe kuchitila kuti kutabi ntenda kubusena.

Mubufwaafwi
Muchi chifwiifwi, acetonitrile, mbuli chintu chiyandikana loko, nchintu chipati mumakkampani miingi. Tachigwasyi buyo kuchita obotu akuzyala kwamakemikalu pesi alimwi chigwasyilizya kuyaambele kwamakwebo aamazubaano. Kakuli kuyaambele kwabusongo, nzila zyakubelesya acetonitrile ziyooba zipati.
