Acetonitrile (CAS 75-05-8) – High Purity Solvent yeMishonga neMakemikoro
Minda mikuru yekushandisa
Mukuongorora makemikari, acetonitrile chinhu chinoshandiswa zvakanyanya pakuongorora high-performance liquid chromatography (HPLC) uye gas chromatography (GC). Ine kunyungudika kwakanaka uye viscosity yakaderera, ichinyungudutsa zvinobudirira mhando dzakasiyana dzemakemikari emuchadenga neasina organic kuti ipe mhedzisiro yakajeka yekuongorora. Acetonitrile inoshandiswawo kugadzira mhinduro dzakajairwa uye mvura yekuenzanisa, ichivimbisa kururama uye kuvimbika kwekuongorora.
Mukugadzirwa kwezvinhu zvipenyu, acetonitrile chinhu chakakosha uye chiri pakati nepakati. Inogona kunyungudutsa mhando dzakasiyana dzemakemikari, ichipa nzvimbo yakagadzikana yekuchinja kwemakemikari. Semuenzaniso, mukugadzirwa kwemamwe mishonga yemishonga uye makemikari ekunhuhwirira, acetonitrile inogona kushanda semushonga wekusimudzira kupindura. Pamusoro pezvo, acetonitrile inogona kutora chikamu mune mamwe maitiro emakemikari kuti igadzire makemikari ane mabasa chaiwo. Semuenzaniso, acetonitrile inogona kuita nucleophilic substitution reactions ne cyano group yayo kuti igadzire amine kana alcohol compounds inoenderana.
Muindasitiri yemishonga, acetonitrile inoshandiswa zvakanyanya mukugadzira nekuchenesa mishonga. Inogona kunyungudutsa mishonga yakasiyana-siyana, zvichiita kuti pave nekushanda kwemakemikari kunoshanda. Semuenzaniso, mukugadzirwa kwemishonga inorwisa mabhakitiriya nemishonga yemwoyo, acetonitrile inogona kushanda semushonga wekuwedzera mhedzisiro uye goho. Pamusoro pezvo, acetonitrile inogona kushandiswa pakugadzira uye kuchenesa mishonga kuti ive nechokwadi chekuchena uye kunaka kwemishonga.
Muindasitiri yezvinonhuwira uye zvizoro, acetonitrile inoshandiswa kugadzira nekucheneswa kwezvinonhuwira. Inogona kushandiswa kubvisa zvinhu zvekunhuhwirira zvechisikigo, zvakaita semafuta akakosha kubva mumiti. Pamusoro pezvo, acetonitrile inogona kushandiswa kugadzira zvinonhuwira zvine hwema hwakasiyana hwezvinonhuwira nezvizoro.
Muindasitiri yezvemagetsi, acetonitrile inoshandiswa semushonga wekuchenesa uye wekunyungudutsa. Inogona kubvisa zvinobudirira marara netsvina pamusoro pezvinhu zvemagetsi, ichivimbisa kuchena uye kushanda zvakanaka kwezvikamu zvemagetsi. Semuenzaniso, mukugadzira semiconductor, acetonitrile inogona kushandiswa kuchenesa pamusoro pemawafer, kubvisa marara ephotoresist nezvimwe tsvina.
Pasinei nekushandiswa kwayo kwakasiyana-siyana, acetonitrile inoshanduka-shanduka uye ine chepfu, uye kushandiswa kwayo nekuchengetwa kwayo kunoda matanho akasimba ekuchengetedza. Acetonitrile inopwa nyore nyore mumhepo, saka inofanira kushandiswa munzvimbo ine mhepo inofefetera zvakanaka. Pamusoro pezvo, mhinduro dzeacetonitrile dzine chepfu shoma, uye michina yekudzivirira yakakodzera inofanira kupfekwa panguva yekushandisa kudzivirira kusangana neganda nemaziso. Mukugadzirwa kwemaindasitiri, kushandiswa kweacetonitrile kunowanzoitika mumasisitimu akavharwa kuderedza kukanganisa kwezvakatipoteredza.

Muchidimbu
Muchidimbu, acetonitrile, semushonga unokosha wemakemikari eorganic uye solvent, inoita basa guru mumaindasitiri akawanda. Haingobatsiri chete pakushanda zvakanaka uye kubereka kwemakemikari asiwo inotsigira kukura kwemaindasitiri emazuva ano. Nekufambira mberi kwetekinoroji, mikana yekushandisa acetonitrile ichave yakakura.
