Boiling point yeacetonitrile: Iyo yakakosha mumuviri paramende muindasitiri yemakemikari
Acetonitrile, seyakakosha organic solvent muindasitiri yemakemikari, inoshandiswa zvakanyanya muminda yezvinodhaka synthesis, makemikari akanaka uye mvura chromatography kuongorora. Kushandisa ma parameter emuviri eacetonitrile akakosha pakushandisa kwayo muindasitiri, pakati pekutyai imwe yenzvimbo inonyanya kuoma paramita. Muro pepa iri, iyo yekubikira yeacetonitrile ichaongororwa zvakadzama, uye pesvedzero yeparamende iyi pamakemikari ichakurukurwa.
Boint pois of Acetonitrile uye kufurira kwayo zvinhu
Pfungwa yekubikira yeacetonitrile inowanzoitika 81.6 ° C (anenge 179 ° F), uye kupisa uku kwakanyanya kukosha kwekukanganisa, kudzokorora uye dzimwe nzira dzekuparadzanisa mumakemikari mumakemikari. Pfungwa yekubikira yeacetonitrile inokanganiswa nezvinhu zvakawanda, kusanganisira kumanikidzwa, kuchena, uye kusanganisa nezvimwe zvinhu. Kazhinji. Semuenzaniso, kudzvinyirirwa kwakaderedzwa, iyo nzvimbo yekubikira yeacetonitrile inoderera, uye ichinzwisisika, pasi pemamiriro akapamanikidzwa, nzvimbo yekubikira inowedzera. Hunhu uhwu hunoita kuti acetonitrile ane mukana wakakura wekushandisa pasi pemamiriro akasiyana ehurongwa.
Kukosha kwekubika nzvimbo yeacetonitrile mune maindasitiri ekushandisa
Kuziva iyo yekubika yeacetonitrile is yakakosha rejekiti kukosha kwekugadzira makemikari emakemikari mamiriro. Mukugadzirwa kwemaindasitiri, zvinowanzo kuve zvakafanira kusanganiswa musanganiswa, uye nzvimbo yekubikira yeacetonitrile inoita kuti ive imwe yezvinhu zvakanaka kwazvo mune maitiro ekugadzirisa solvent kupora. Semuenzaniso, mumvura Chromatography kuongorora, iyo yakakodzera yekubika nzvimbo yeacetonitrile inogonesa kutuka pakudziya kwakaderera, kudzivisa kunyanyisa kudzvinyirira kwemuenzaniso. MuSynthetic Chemistry, kudzora tembiricha yekudzidzira padyo nepazasi peiyo yekubikira yeacetonitrile inobatsira kuti ive yekuchengetedza kwezvigadzirwa uye nekuchena kwezvigadzirwa.
Maitiro ekushandisa iyo inovhara point yeacetonitrile kuti isarudze maitiro ekugadzira
Nekuziva uye kunzwisisa iyo yekubikira yeacetonitrile, mainjiniya anogona kugadzirisa maitiro ekugadzira kuti avandudze kushanda zvakanaka uye kuderedza mari. Semuenzaniso, mukuita disctilation, iyo yekubikira yeacetonitrile inogona kushandiswa seyakakosha chikonzero chekuisa tembiricha yekushandisa yeiyo disumn yekusagadzikana kwekupatsanurwa kwekupatsanurwa. Nekugadzirisa maitiro ekumanikidzwa system kuti uchinje nzvimbo yekubika yeacetonitrile, zvinokwanisika kuwana mimwezve yekugadzira mishonga yekugadzira mumamiriro akasiyana siyana mumamiriro ezvinhu akasiyana. Iyi nzira haigone kungoponesa simba zvinobudirira, asi zvakare dzivandudza zvakare kuchengeteka uye kugadzikana kweiyo yakazara tambo yekugadzira.
Pfupiso
Pfungwa yekubika yeacetonitrile chikamu chakakosha chemuviri mumakemikari indasitiri, iyo inobata zvakananga kugadzirwa uye kushandisirwa kwemabasa akasiyana emakemikari. Kutanga kubva pane zvakakosha zvivakwa zveacetonitrile zvinhu zvezvinhu zvekushandisa zvaro zvinogona kubatsira mainjiniya ekugadzira maitiro, achivandudza chigadzirwa mhando uye kuzadzisa chinangwa chekusimudzira. Nekunzwisisa zvizere uye kushandisa iyo nzvimbo yekubika yeacetonitrile, makambani emakemikari anokwanisa kutora mukana wemakwikwi emusika anotyisa.
