Methanol kunyeisopropanolzizinyibilikisi ezibini ezisetyenziswa ngokuqhelekileyo kwimizi-mveliso.Ngelixa babelana ngokufana okuthile, bakwanazo iipropathi ezahlukeneyo kunye neempawu ezibenza bahluke.Kweli nqaku, siza kuphanda kwiinkcukacha zezi zinyibiliki zimbini, sithelekisa iimpawu zazo zomzimba kunye neekhemikhali, kunye nokusetyenziswa kwazo kunye neeprofayili zokhuseleko.

Masiqale nge-methanol, eyaziwa ngokuba yi-alcohol yomthi.Lulwelo olucacileyo, olungenambala oludityaniswa namanzi.I-Methanol ineqondo eliphantsi lokubila elingu-65 degrees Celsius, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwizicelo zobushushu obuphantsi.Inomlinganiselo ophezulu we-octane, oku kuthetha ukuba ingasetyenziselwa njenge-solvent kunye ne-anti-knock agent kwi-petroli.

I-Methanol ikwasetyenziswa njenge-feedstock kwimveliso yezinye iikhemikhali, ezifana ne-formaldehyde kunye ne-dimethyl ether.Ikwasetyenziswa kwimveliso ye-biodiesel, umthombo wamafutha ohlaziyekayo.Ukongeza kwizicelo zayo zoshishino, i-methanol isetyenziselwa ukuveliswa kwee-varnishes kunye ne-lacquers.

Ngoku makhe siphendule ingqalelo yethu kwi-isopropanol, eyaziwa ngokuba yi-2-propanol okanye i-dimethyl ether.Esi sinyibilikisi sikwacacile kwaye asinambala, kunye neqondo lokubila elingaphezulu kancinane kunemethanol kuma-82 degrees celsius.I-Isopropanol ixubene kakhulu kunye namanzi kunye ne-lipids, iyenza i-solvent egqwesileyo yoluhlu olubanzi lwezicelo.Ngokuqhelekileyo isetyenziswe njenge-agent agent kwi-paint thinners kunye nokuveliswa kweeglavu ze-latex.I-Isopropanol iphinda isetyenziswe kwimveliso ye-adhesives, sealants, kunye nezinye iipolymers.

Xa kuziwa kukhuseleko, zombini i-methanol kunye ne-isopropanol zineengozi zazo ezizodwa.IMethanol inetyhefu kwaye inokubangela ubumfama ukuba itshizwe emehlweni okanye ityiwe.Ikwanokutsha kakhulu kwaye iyadubula xa ixutywe nomoya.Ngakolunye uhlangothi, i-isopropanol inomlinganiselo ophantsi wokutsha kwaye ayiqhume kakhulu kune-methanol xa ixutywe nomoya.Nangona kunjalo, isavutha kwaye kufuneka iphathwe ngononophelo.

Ukuqukumbela, i-methanol kunye ne-isopropanol zombini zizinyibilikisi ezixabisekileyo zoshishino ezineempawu zazo ezizodwa kunye nokusetyenziswa.Ukhetho phakathi kwabo luxhomekeke kwiimfuno ezithile zesicelo kunye neprofayili yokhuseleko lwe-solvent nganye.I-Methanol inendawo yokubila esezantsi kwaye iqhuma ngakumbi, ngelixa i-isopropanol inendawo ephezulu yokubilisa kwaye ayiqhume kancinci kodwa isavutha.Xa ukhetha i-solvent, kubalulekile ukuqwalasela iimpawu zayo ezibonakalayo, ukuzinza kweekhemikhali, ubuthi, kunye neprofayili yokutsha ukuze kuqinisekiswe ukusetyenziswa okukhuselekileyo nokusebenzayo.
