Uhlalutyo oluneenkcukacha lwendawo yokubilisa ye-methanol
I-Methanol yenye yezona zinto zibalulekileyo kwimveliso yeekhemikhali, kwaye isetyenziswa ngokubanzi njengamafutha, i-solvent kunye ne-chemical synthesis. Kweli phepha, siya kuhlalutya ngokubanzi umba we "Methanol Boiling Point", kwaye sixoxe nzulu ngeempawu ezibonakalayo ze-methanol, izinto ezichaphazela indawo yokubilisa kunye nokubaluleka kwayo kwizicelo zoshishino.
Iimpawu zomzimba ezisisiseko zemethanol
I-Methanol, ekwabizwa ngokuba butywala benkuni okanye umoya womthi, ifomula yekhemikhali ye-CH₃OH, yeyona khompawundi ilula yotywala. Njengolwelo olungenambala, olunokutsha, imethanol iyaguquguquka kakhulu kwaye inetyhefu egqithisileyo. Inqaku layo lokubilisa liyiparameter ebalulekileyo yokuqonda iimpawu ze-methanol. Kuxinzelelo lwe-atmospheric, i-methanol ineqondo lokubila elingu-64.7 ° C (148.5 ° F), nto leyo eyenza ukuba ibe lula ukuba ibe ngumphunga kwiqondo lobushushu begumbi. Ngoko ke, xa uphatha kwaye ugcina i-methanol, kubalulekile ukuqwalasela ukuguquguquka kwayo kunye nokutsha kunye nokuthatha amanyathelo afanelekileyo okhuseleko.
Izinto ezichaphazela indawo yokuBilisa yeMethanol
Kukho izinto ezininzi ekufuneka zithathelwe ingqalelo xa uqonda umba "wendawo yokubilisa yemethanol". Ulwakhiwo lwemolekyuli yemethanol imisela indawo yayo ephantsi yokubila. I-molecule ye-methanol iqukethe iqela le-methyl (CH₃) kunye neqela le-hydroxyl (OH) kwaye inobunzima obuphantsi be-molecular. Ngenxa yobukho be-hydrogen bonding kwiqela le-hydroxyl, oku kuphakamisa indawo ebilayo ngandlel 'ithile, kodwa isengaphantsi kunezinye iialkoholi ezinobunzima obuphezulu bemolekyuli.
Iimeko zangaphandle ezinjengokutshintsha koxinzelelo nazo zinokuchaphazela indawo yokubilisa ye-methanol. Ngaphantsi kweemeko zoxinzelelo oluphantsi, indawo yokubilisa ye-methanol iyancipha, ngelixa phantsi kweemeko zoxinzelelo oluphezulu, iyanda. Ngoko ke, kunokuba yimfuneko ukulawula i-methanol evaporation kunye nenkqubo ye-condensation ngokulungelelanisa uxinzelelo kwiinkqubo ezahlukeneyo zoshishino.
Ukubaluleka kwendawo yokubilisa yemethanol kwizicelo zamashishini
Indawo yokubilisa ye-methanol ibalulekile kwisicelo sayo kwimveliso yeekhemikhali. Ngokomzekelo, kwimveliso ye-methanol kunye ne-distillation, kubalulekile ukulawula ukushisa okufanelekileyo kunye noxinzelelo lokwahlula ngokufanelekileyo kunye nokucocwa kwe-methanol. Ngenxa yeqondo eliphantsi lokubilisa, i-methanol inokuthi ibe ngumphunga kuxinzelelo lwe-atmospheric isebenzisa izixhobo zokufudumeza eziqhelekileyo, eziluncedo malunga nokugcinwa kweendleko zamandla.
Indawo yokubilisa ephantsi yeMethanol ikwayenza ibe sisinyibilikisi esifanelekileyo, ngakumbi kwizicelo ezifuna ukuvela komphunga okukhawulezayo, okufana neepeyinti kunye nezicoci. Ngexesha lokusetyenziswa, ubushushu kunye nokuphuma komoya kwindawo yokusebenza kufuneka kulawulwe ngokungqongqo ukuthintela ukwakheka komphunga we-methanol, ngaloo ndlela ukuphepha umlilo okanye iingozi zempilo.
Ukuqukumbela
Kolu hlalutyo lungentla, kunokubonwa ukuba ukuqonda "indawo yokubilisa ye-methanol" ibalulekile ekusetyenzisweni okukhuselekileyo nokusebenzayo kwe-methanol kwizicelo zamashishini. Indawo yokubilisa ye-methanol ayichaphazeli kuphela iimpawu zayo zomzimba kunye neemeko zokusebenza, kodwa ihambelana ngokuthe ngqo nokukhethwa kwayo kunye nokusetyenziswa kwizicelo zeekhemikhali ezahlukeneyo. Olu lwazi lunceda ukwandisa iinkqubo zoshishino, ukonga amandla kunye nokwandisa ukusebenza kakuhle kwemveliso.
