Boiling Point yen-Hexane: Ongororo yeInokosha Parameter muKemikari Indasitiri
Hexane (n-Hexane) yakajairika organic compound inoshandiswa mumakemikari, mishonga, pendi uye zvinonyungudutsa maindasitiri. Iyo yekubikira kwayo inzvimbo yakakosha yemuviri paramende inobata zvakananga mashandisirwo ayo uye kubata mumaindasitiri maitiro. Muchikamu chino, tichaongorora zvakadzama ruzivo rwen-hexane yekubikira poindi, kusanganisira tsananguro yaro, zvinofurira zvinhu uye zvinoshanda.
Izvo zvakakosha zvemuviri zvimiro zven-hexane
Hexane imvura isina ruvara uye yakajeka ine kemikari formula C6H14, inova yealkanes. Morekuru rayo rine maatomu ecarbon matanhatu uye gumi nemana maatomu ehydrogen. Nekuda kwekufananidzwa kweiyo molecular chimiro chehexane, isiri-polar molecule ine yakaderera polarity, izvo zvinokonzeresa kusapindirana kwakashata nezvinhu zvepolar zvakaita semvura, uye inonyanya kukodzera kusangana nemamwe asiri-polar solvents.
Nzvimbo yekuvira yehexane chinhu chakakosha chemuviri uye inotsanangurwa setembiricha apo hexane iri mumvura inoshandurwa kuita gaseous state payakajairwa atmospheric pressure (1 atm, 101.3 kPa). Zvinoenderana nedata rekuyedza, nzvimbo yekubikira yen-hexane i68.7 °C.
Zvinhu zvinokanganisa kuvira kwehexane
Molecular structure
Morekuru rehexane ishetani rakatwasuka rine maatomu ekabhoni akarongwa mumutsara. Chimiro ichi chinoguma nemasimba asina simba evan der Waals pakati pemamorekuru saka n-hexane ine nzvimbo yakaderera yekuvira. Kusiyana neizvi, maalkanes ane mamorekuru akafanana asi chimiro chakaoma, senge cyclohexane, ane masimba akasimba epakati uye nzvimbo yepamusoro yekubikira.

Mhedzisiro yeatmospheric pressure
Iyo yekubikira poindi ye-n-hexane inowanzoenderana nemamiriro eiyo standard atmospheric pressure. Kana kudzvinyirirwa kwemhepo munzvimbo yekunze kuchichinja, iyo chaiyo yekubikira yehexane inoshanduka zvakare. Pakudzvinyirirwa kwakaderera, sekunge muvacuum distillation, nzvimbo yekubikira yehexane yakadzikira zvakanyanya, zvichiita kuti iwedzere kushanduka.

Kufurira kuchena uye musanganiswa
Kuchena kwehexane kunokanganisa zvakananga kuvira kwayo. Kana hexane iine tsvina kana kuita musanganiswa nemamwe makomisheni, panofashaira inogona kuchinja. Semuenzaniso, kana hexane yakasanganiswa nezvimwe zvinwiwa mumakemikari process, iyo yekuvira kwayo inogona kudzikiswa (kuumbwa kweazeotropes), iyo inogona kushandura maitiro ayo evaporation.

Kukosha kweHexane Boiling Point muIndustrial Applications
Solvent Applications
Hexane inoshandiswa zvakanyanya sechinhu chinonyungudutsa, kunyanya mukubvisa girizi, kugadzira anonamira uye maindasitiri ependi. Mumashandisirwo aya, panofashaira poindi yehexane inotaridza mwero wayo wekubuda. Nekuda kwekudzika kwayo kubikira, hexane inokwanisa kunyungudika nekukasira, ichideredza zvisaririra zvemunyungudutsa nekudaro ichiva nechokwadi chemhando yechigadzirwa.

Distillation uye kupatsanura maitiro
Mune petrochemical uye yekunatsa maitiro, hexane inowanzoshandiswa mukugovewa kwemafuta asina kuchena. Nekuda kwekudzikira kwayo kubikira, kufefetedza uye kudzoreredza maitiro ehexane mumakoramu edistillation anogona kubatsira kuiparadzanisa kubva kune mamwe alkanes kana zvinonyungudutsa. Kuwana nzvimbo yekubikira yen-hexane kurudyi kwakakosha kudzora tembiricha uye kumanikidza mamiriro eiyo distillation maitiro kuti ave nechokwadi chekuparadzana kwakanaka.

Mafungiro Ezvakatipoteredza uye Kuchengetedzwa
Nekuti hexane ine nzvimbo yakaderera kuvira, inoita kushanduka pamhepo tembiricha, izvo zvinosimudza nyaya yekubuda kwevolatile organic compounds (VOCs). Panguva yekushanda, kufefetera kunofanirwa kukwidziridzwa uye matanho akakodzera ekudzivirira anofanirwa kushandiswa kudzivirira mhute yehexane kudzivirira njodzi dzinogona kuitika pahutano nekuchengetedza.

Kupfupikisa
Iyo yemuviri parameter yekubikira poindi yehexane ine yakakosha inoshanda mashandisirwo muindasitiri yemakemikari. Kuongorora huwandu hwezvinhu zvakadai semagadzirirwo emagetsi, kumanikidzwa kwemhepo uye kuchena, zvinogona kuonekwa kuti nzvimbo yekubikira haisi kungokanganisa kushanduka kwen-hexane uye nzira ye distillation, asi inotarisa kuchengetedzwa kwayo kwekushanda munzvimbo dzakasiyana-siyana dzemaindasitiri. Ingave yakashandiswa sechinhu chinonyungudutsa kana seyakagadzirwa kupatsanurwa, kunzwisisa kwakaringana uye kushandiswa kwenzvimbo yekubikira yehexane kwakakosha kuvandudza kubereka uye kuve nechokwadi chekuchengetedza.
