Kuongorora kwakadzama kwenzvimbo yekubikira yemethanol
Methanol chimwe chezvakanyanya kukosha zvekushandisa muindasitiri yemakemikari, uye inoshandiswa zvakanyanya sehuni, solvent uye makemikari synthesis. Mupepa rino, tichaongorora zvakadzama nyaya ye "Methanol Boiling Point", uye tokurukura zvakadzama maitiro emuviri we methanol, izvo zvinokanganisa kuvira kwayo uye kukosha kwayo mukushandiswa kwemaindasitiri.
Izvo zvakakosha zvemuviri zvemethanol
Methanol, inozivikanwawo sehuni doro kana mweya wehuni, makemikari formula yeCH₃OH, ndiyo yakapfava doro musanganiswa. Semvura isina ruvara, inobvira moto, methanol ine mwero uye ine muchetura zvakanyanya. Iyo yekubikira kwayo ndiyo yakakosha parameter yekunzwisisa zvimiro zvemethanol. Pamhepo yemhepo, methanol ine nzvimbo yekuvira inosvika 64.7°C (148.5°F), inoita kuti ive nyore kufefeterwa patembiricha yekamuri. Nokudaro, kana uchibata nekuchengetedza methanol, zvakakosha kufunga nezvekusagadzikana kwayo uye kupisa uye kutora matanho akakodzera ekuchengetedza.
Zvinhu Zvinokanganisa Kubikira Poindi yeMethanol
Pane zvinhu zvakati wandei zvinofanirwa kuverengerwa pakunzwisisa nyaya ye "methanol boiling point". Iyo molecular chimiro che methanol inosarudza yakaderera kuvira kwayo. Iyo methanol molecule ine methyl boka (CH₃) uye hydroxyl boka (OH) uye ine yakaderera molecular uremu. Nekuda kwekuvapo kwehydrogen bonding muboka rehydroxyl, izvi zvinosimudza pairi kufashaira zvakati, asi ichiri kuderera pane mamwe madoro ane huremu hwemamorekuru.
Mamiriro ekunze akadai sekuchinja kwekumanikidza anogonawo kukanganisa nzvimbo yekuvira yemethanol. Pasi pemamiriro ekunze ekudzvinyirira, nzvimbo yekubikira yemethanol inoderera, asi pasi pemamiriro ekumanikidzwa kwakanyanya, inowedzera. Naizvozvo, zvingave zvakafanira kudzora methanol evaporation uye condensation maitiro nekugadzirisa kudzvanywa mune akasiyana maindasitiri maitiro.
Kukosha kwemethanol yekubikira poindi mumaindasitiri ekushandisa
Iyo yekubikira yemethanol yakakosha pakushandiswa kwayo mukugadzirwa kwemakemikari. Semuenzaniso, mukugadzira methanol uye distillation, zvakakosha kudzora tembiricha yakakodzera uye kudzvanywa kwekupatsanurwa kwakanaka uye kucheneswa kwemethanol. Nekuda kwekudzika kwayo kubikira, methanol inogona kunyungudutswa pamhepo yemhepo uchishandisa yakajairwa kudziyisa michina, iyo inobatsira maererano nekuchengetedza mari yesimba.
Methanol's low boiling point inoitawo kuti ive yakanaka yekunyungudutsa, kunyanya mumaapplications anoda kukurumidza kubuda, senge pendi nekuchenesa. Panguva yekushandiswa, tembiricha uye kufefetedza kwenzvimbo yekushanda kunoda kunyatsodzorwa kudzivirira kuvakwa kwemethanol vapour, nokudaro kudzivirira moto kana njodzi dzehutano.
Mhedziso
Kubva pane ongororo iri pamusoro, zvinogona kuonekwa kuti kunzwisisa "poindi yekubikira yemethanol" kwakakosha pakushandiswa kwakachengeteka uye nemazvo kwemethanol mumaindasitiri ekushandisa. Iyo yekubikira yemethanol haingokanganisa maitiro ayo emuviri uye mamiriro ekushanda, asi zvakare yakanangana nekusarudzwa kwayo uye kushandiswa mumhando dzakasiyana dzemakemikari. Ruzivo urwu runobatsira kukwirisa maindasitiri maitiro, kuchengetedza simba uye kuwedzera kugadzirwa kwakanaka.
