Kuongororwa kwakadzama kweiyo inovhara point ye methanol
Methanol ndeimwe yezvakanyanya kukosha zvigadzirwa mumakemikari indasitiri, uye inoshandiswa zvakanyanya sehuni, solvent uye makemikari synthesis. Mune ino bepa, tichaongorora zvakadzama nyaya ye "methanol inovhara pfungwa", uye kurukura zvakadzama zvivakwa zve methanol, zvinhu zvinokanganisa nzvimbo yayo yekubikira uye kukosha kwayo mune maindasitiri ekushandisa.
Zvinhu zvekutanga zvemuviri zve methanol
Methanol, anozivikanwawo sedoro doro kana mweya wemapuranga, makemari formula ye ch₃oh, ndiyo doro rakareruka rakaenzana. Semvura isina ruvara, inopisa, methanol inoenderana zvakanyanya uye ine chepfu zvakanyanya. Pfungwa yayo yekubikira itsivi rakakosha rekunzwisisa zvivakwa zve methanol. Kumutamanikidzwa kumanikidzwa, methanol ine nzvimbo yekubika ye64.7 ° C (148.5 ° F), iyo inoita kuti iite kuti isanyanya kumuka kwemhepo tembiricha. Naizvozvo, pakubata uye kuunganidza methanol, zvakakosha kuti ufunge nezve kuwanda uye kupisa uye kutora matanho akakodzera ekuchengetedza.
Zvinhu zvinokanganisa nzvimbo yekubikira yeMethanol
Pane zvinhu zvinoverengeka izvo zvinofanirwa kuongororwa kana uchinzwisisa nyaya ye "methanol boling point". Iyo moleky chimiro che methanol inosarudza yayo yakaderera inodonha point. Iyo methanol molecule ine methyl boka (CH₃) uye hydroxyl boka (Oh) uye ine yakaderera molecular uremu. Nekuda kwekuvapo kweHydrogen Kubatanidza muHydroxyl Boka, izvi zvinomutsa pfungwa yayo yekubikisa zvimwe, asi ichiri yakaderera pane mamwe macalools ane manyoro emanyorero.
Mamiriro ekunze akadai sekuchinja kwekumanikidza anogona zvakare kubata iyo inovhara pfungwa yeMethanol. Mumamiriro ezvinhu akaderera ekudzvinyirira, iyo yekubikira methanol inoderera, nepo pasi pemamiriro ekumanikidzwa kwepamhepo, zvinowedzera. Naizvozvo, zvingave zvakakodzera kudzora iyo methanol evapandation nekudzokorora nekugadzirisa kudzvanywa mumabasa akasiyana maindasitiri.
Kukosha kwe methanol booling point mune maindasitiri ekushandisa
Iyo yekubikira point ye methanol yakakosha pakushandisa kwayo mukugadzirwa kwemakemikari. Semuenzaniso, mu methanol kugadzirwa uye distillation, zvakashora kudzora tembiricha chaiyo uye kumanikidzwa kwekupatsanurwa kwekuparadzaniswa uye kucheneswa kweMethanol. Nekuda kweiyo yakaderera yekubika point, methanol inogona kuiswa pakudzvanywa kwemhepo ichishandisa michina yekudziya, iyo inobatsira maererano nekuchengetedza mari yemubhadharo.
Methanol's yakaderera-yekubika nzvimbo inoitawo kuti ive yakakodzera solvent, kunyanya mune zvinoshandiswa zvinoda kubuda kwekunze, sekupenda nevachenesa. Munguva yekushandisa, tembiricha uye mhepo yekushanda nharaunda inoda kudzorwa zvakanyanya kudzivirira kuvaka-kumusoro kwe methanol vapor, nekudaro kudzivirira moto kana hutano hutano.
Mhedziso
Kubva pane ongororo dziri pamusoro, rinogona kuona kuti vanonzwisisa "methonol yeMethanol" yakakosha kushandiswa kwakachengeteka uye kwakakodzera kwekushandisa methanol mune maindasitiri ekushandisa maindasitiri. Pfungwa yekubika ye methanol isingabate chete zvivakwa zvaro uye mamiriro ekushanda, asi zvine hukama zvakanangana nekusarudzwa kwayo uye kushandiswa mumanyorero akasiyana emakemikari. Zivo iyi inobatsira kurongedza maindasitiri maitiro, chengetedza simba uye kuwedzera kugadzirwa kwekugadzira.
