Boiling point ye trichloromethane: Kunzwisisa mune iyi yakakosha kemikari parameter
Trichloromethane, kemikari formula CHCl₃, inowanzonzi chloroform, yakakosha organic solvent. Inoshandiswa zvakanyanya muindasitiri nemarabhoritari, uye zvimiro zvayo zvemuviri, kunyanya nzvimbo yekubikira, ndizvo zvinotemerwa nenzvimbo dzekushandisa uye chengetedzo. Mubepa rino, tichatarisa zvakadzama pairi kufashaira kwetrichloromethane toongorora kukosha kwayo muindasitiri yemakemikari.
Boiling point ye trichloromethane uye kukosha kwayo kwemuviri
Kuvira kwe trichloromethane i 61.2°C (kana 334.4 K). Panofashaira tembiricha inoshandurwa mvura kuita gasi pane imwe pressure (kazhinji standard atmospheric pressure, kana 101.3 kPa). Kana iri trichloromethane, nzvimbo yayo yakadzikira yekubikira inoita kuti ive yakanyanya kuvhurika patembiricha yekamuri, izvo zvine chekuita nekushandiswa kwayo muindasitiri yemakemikari.
Zvinhu zvinokanganisa nzvimbo yekubikira ye trichloromethane
Iyo yekubikira poindi ye trichloromethane inobatwa nehuwandu hwezvinhu, kunyanya iyo intermolecular van der Waals masimba uye polarity yemorekuru. Iyo huru electronegativity yemaatomu eklorini mu trichloromethane molecule inoipa imwe polarity, inotungamira kune kuvepo kwemamwe ma dipole-dipole masimba pakati pemamorekuru. Kuvapo kweaya ma intermolecular masimba anobvumira trichloromethane kukunda aya masimba akabatana uye kushandurudza kuita gasi chete patembiricha chaiyo. Nekuda kweizvozvo, kubikira kwayo kwakakwira kune mamwe mamorekuru asiri epolar akadai semethane (boiling point -161.5 ° C) asi yakaderera pane yemvura (boiling point 100 ° C), ichiratidza masimba ayo epakati-simba intermolecular interaction forces.
Kukosha kweiyo yekubikira poindi ye trichloromethane mumaindasitiri maapplication
Iyo yekubikira poindi ye trichloromethane igwara rakakosha pakushandiswa kwayo muindasitiri. Kudzikira kwayo kuvirisa kunoita kuti ive inoshanda organic solvent, kunyanya kune maitiro anoda kukurumidza kubuda. Semuenzaniso, mukugadzirwa kwemakemikari, trichloromethane inowanzoshandiswa mukubvisa, kunyungudutswa uye kuchenesa maitiro nekuda kwekugona kwayo kubuda mhepo nekukasira uye kugona kwayo kunyungudutsa zvinhu zvakawanda zveorganic. Nekuda kwekudzikira kwayo kubikira, kusagadzikana kunofanirwa kuverengerwa mukugadzirwa kwemidziyo yemaindasitiri, kunyanya mumatanho anosanganisira distillation uye kudzoreredza kwesolvent, kuve nechokwadi chekushanda kwakachengeteka uye kwakanaka.
Mhedzisiro yenzvimbo yekubikira ye trichloromethane pane kuchengeteka
Iyo yekubikira poindi ye trichloromethane zvakare ine yakananga kukanganisa kwekuchengetedza kwayo uye kushandiswa kwayo. Nekuda kwekusagadzikana kwayo kukuru patembiricha yemumba, inoita kuti igadzire hupfu hunopfuta uye hune chepfu mumhepo. Izvi zvinoda kufefetedza kwakanaka uye kushandiswa kwemidziyo yakavharwa yakakodzera yekuchengetedza uye kushandiswa kwayo. Kuziva pairi kufashaira yetrichloromethane kunogona kubatsira makambani emakemikari kuti aise matanho akakodzera ekuchengetedza kudzivirira kubuda netsaona uye kuburitswa kwegasi nekuda kwekupisa kwakanyanya.
Mhedziso
Ongororo yenzvimbo yekubikira ye trichloromethane haingobatsiri kuti tinzwisise zviri nani zvimiro zvekemikari iyi, asi zvakare inopa yakakosha theoretical hwaro hwekushandiswa kwayo muindasitiri yemakemikari. Kubva pakurongeka kwayo kwemamorekuru kusvika kumashandisirwo ayo anoshanda, nzvimbo yekubikira yetrichloromethane inoita basa rakakosha mukugadzira makemikari dhizaini nekuchengetedza kuchengetedza. Nekuwana kunzwisisa kwakadzama kweiyo kuvira kweiyo trichloromethane, tinogona kushandisa zvirinani chinhu ichi uye tive nechokwadi chekushanda kwayo uye kuchengetedzeka mukushandisa kwakasiyana.
