Zvinhu zvinokanganisa nzvimbo yekubikira ye tetrahydrofuran uye inoshanda mashandisirwo
Tetrahydrofuran (THF) inoshandiswa zvakanyanya organic solvent muindasitiri yemakemikari ine yakanyanya solvency uye yakaderera muchetura, uye nekudaro yakashandiswa zvakanyanya muminda yemishonga, makemikari uye zvinhu sainzi. Mupepa rino, tichakurukura zvakadzama maitiro ekutanga eiyo tetrahydrofuran yekubikira, izvo zvinoikanganisa uye kukosha kwayo mukushandisa zvinoshanda.
I. Zvinhu zvakakosha zve tetrahydrofuran uye nzvimbo yayo yekubikira
Tetrahydrofuran (THF) is a cyclic ether ine kemikari formula C4H8O. Sechinonyungudutsa chinowanzo shandiswa, tetrahydrofuran imvura isina ruvara uye inoonekera pane tembiricha yekamuri uye ine yakanyanya kushanduka. Tetrahydrofuran ine poindi yekuvira ingangoita 66°C (inenge 339 K), zvinoita kuti zvive nyore kufefetedza nekupora mumakemikoro akawanda. Tetrahydrofuran's low boiling point inorevawo kuti inogona kubviswa kubva kune reaction system nekukasira, ichideredza kukanganiswa neanotevera maitiro.
Zvinhu zvinokanganisa nzvimbo yekubikira ye tetrahydrofuran
Kunyangwe iyo yekubikira ye tetrahydrofuran ine kukosha kwakagadziriswa mumakemikari mabhuku, mukuita iyo yekubikira ye tetrahydrofuran inogona kukanganiswa nehuwandu hwezvikonzero:
Kupesvedzera kwe ambient pressure: Iyo yekuvira ye tetrahydrofuran inosiyana ne ambient pressure. Pakumanikidzwa kweatmospheric, panovira tetrahydrofuran i66°C. Pasi pekudzvinyirirwa kwepamusoro kana kuderera, nzvimbo yekubikira ichachinja maererano. Kazhinji, kukwira kwesimba, kunowedzera kuvira kwe tetrahydrofuran; zvakasiyana, mune vacuum, nzvimbo yekubikira ichaderera.

Pesvedzero yekuchena: Kusachena mu tetrahydrofuran kuchave nemhedzisiro pairi kuvira. Kana mhinduro ye tetrahydrofuran ine mvura yakawanda kana zvimwe zvinosvibisa zvinonyungudutsa, nzvimbo yayo yekubikira inogona kusiyana kubva kune yakachena tetrahydrofuran. Kunyanya, kuvepo kwehunyoro, iyo inonyungudika zvishoma mumvura, inogona kuumba azeotrope ine THF, zvichikonzera shanduko diki mukubikira.

Azeotropic phenomena: Mukuita, tetrahydrofuran inowanzosanganiswa nezvimwe zvinonyungudutsa kugadzira azeotropic musanganiswa. Mapoinzi ekubikira emusanganiswa akadaro anowanzo siyana neaya echikamu chimwe chete uye azeotropy anoomesa maitiro ekuparadzanisa. Naizvozvo, pakusarudza tetrahydrofuran semushonga, zvakakosha kuti unzwisise maitiro ayo azeotropic nemamwe makomisheni.

III. Kushanda kwekushandisa kwe tetrahydrofuran yekubikira poindi muindasitiri
Iyo yekubikira poindi zvivakwa zve tetrahydrofuran zvine zvakakosha mashandisirwo mukugadzirwa kwemakemikari:
Kudzoreredza uye kushandiswazve kwezvinonyungudutsa: Sezvo tetrahydrofuran ine yakaderera kubikira poindi, zviri nyore kudzoserwa kubva mukuita musanganiswa ne distillation kana mamwe maitiro ekuparadzanisa. Ichi chivakwa hachingobatsiri kudzikisira mutengo wekugadzira, asi zvakare chinoderedza kukanganisa kwezvakatipoteredza.

Zvishandiso mu polymerisation: Mune mamwe maitiro epolymerisation, tetrahydrofuran ine ine mwero yekubikira poindi, iyo inobvumira kuti inyatso kudzora tembiricha yekuita uye kuona kuti maitiro anofamba zvakanaka. Kusagadzikana kwayo kunogonawo kukurumidza kubviswa pakupera kwekuita, kudzivirira kukanganisa kwakashata pakuchena kwechigadzirwa.

Kushandiswa mukugadzirwa kwezvinodhaka: Tetrahydrofuran inowanzoshandiswa sechinhu chinonyungudutsa mukugadzirwa kwezvinodhaka, iyo inofashaira nzvimbo ine mwero, iyo inobatsira kune kunyatso kudzora mamiriro ekuita. Tetrahydrofuran's inokurumidza evaporation zvimiro inoita kuti inyatsoshanda mumashure-kuita yekuzviparadzanisa nevamwe uye maitiro ekuchenesa.

Mhedziso
Iyo yekubikira poindi ye tetrahydrofuran ndeimwe yeayo akakosha zvivakwa mumaindasitiri maapplication. Kunzwisisa nzvimbo yekubikira ye tetrahydrofuran uye zvinhu zvinofurira zvinogona kubatsira makambani emakemikari kudzora zvirinani mamiriro ekuita mukugadzirwa chaiko uye kuvandudza kunaka nekugadzirwa kwezvigadzirwa. Kushandisa zvine hungwaru kwehunhu hwayo hwakaderera hunofashaira hunogona kubatsira kuwana kudzokorodza kwakanaka kwezviwanikwa uye kusimudzira kwakasimba kwenzvimbo. Pakusarudza nekushandisa tetrahydrofuran semunyungudutsa, kutarisisa kwakazara kwehunhu hwayo hwekubikira uye kupesvedzera zvinhu ndiyo kiyi yekuve nechokwadi chekuchengetedza uye kugona kwemakemikari maitiro.
