Indawo yokuBilisa ye-Isopropanol: Uhlalutyo oluneenkcukacha kunye nezicelo
I-Isopropanol, eyaziwa ngokuba yi-isopropyl alcohol okanye i-2-propanol, yinto eqhelekileyo ye-solvent esetyenziswa kakhulu kwiikhemikhali, amayeza kunye nobomi bemihla ngemihla. Indawo yokubilisa iyipharamitha ebaluleke kakhulu xa kuxoxwa ngeempawu ze-Isopropanol. Ukuqonda ukubaluleka kwendawo yokubilisa ye-isopropanol ayincedi kuphela ekuphuculeni izicelo zayo zoshishino kodwa nasekukhuseleni ukusebenza kwibhubhoratri.
Iipropati eziSisiseko kunye noLwakhiwo lwe-Isopropyl Alcohol
I-Isopropyl alcohol ine-molecular formula C₃H₈O kwaye ikwiqela leealkoholi. Kwisakhiwo salo se-molecular, iqela le-hydroxyl (-OH) lifakwe kwi-athomu ye-carbon yesibini, kwaye esi sakhiwo sinquma iimpawu ezibonakalayo kunye neekhemikhali ze-isopropanol. Njenge-solvent ye-polar ephakathi, i-isopropyl alcohol iyaxubana namanzi kunye nezinyibilikisi ezininzi ze-organic, nto leyo eyenza ukuba igqwese ekunyibilikeni nasekuxubeni uluhlu olubanzi lweekhemikhali.
Ukubaluleka koMzimba kwe-Isopropyl Alcohol Boiling Point
I-alcohol ye-Isopropyl ineqondo lokubila elingu-82.6 ° C (179 ° F), lilinganiswe kuxinzelelo oluqhelekileyo lwe-atmospheric (1 atm). Eli nqanaba lokubilisa lisisiphumo samandla okudibanisa i-hydrogen phakathi kweemolekyuli zotywala ze-isopropyl. Nangona i-isopropanol inobunzima obuncinane be-molecular, ubukho bamaqela e-hydroxyl kwi-molecule yenza ukubunjwa kweebhondi ze-hydrogen phakathi kwee-molecule, kwaye le bhondi ye-hydrogen iphakamisa umtsalane we-intermolecular, ngaloo ndlela ukwandisa indawo yokubilisa.
Xa kuthelekiswa nezinye iikhompawundi zesakhiwo esifanayo, njenge-n-propanol (indawo yokubilisa ye-97.2 ° C), i-isopropanol inomlinganiselo ophantsi wokubilisa. Oku kungenxa yesikhundla seqela le-hydroxyl kwi-molecule ye-isopropanol ebangela ukuba i-intermolecular hydrogen bonding ibuthathaka, iyenze ibe shushu ngakumbi.
Impembelelo ye-Isopropyl Alcohol Boiling Point kwi-Industrial Application
Ixabiso eliphantsi kakhulu lendawo yokubilisa ye-isopropyl alcohol yenza ukuba igqwese kwi-industrial distillation kunye nokulungiswa. Ngenxa yeqondo eliphantsi lokubilisa, xa kusenziwa ukuhlukana kwe-distillation, i-isopropanol inokwahlulwa ngokufanelekileyo kumaqondo okushisa aphantsi, ukugcina ukusetyenziswa kwamandla. I-Isopropanol iyaguquguquka kumaqondo aphantsi, okwenza ukuba isetyenziswe ngokubanzi kwiingubo, ii-agent zokucoca kunye ne-disinfectants. Kwezi zicelo, i-isopropyl alcohol's quick evaporation properties isusa ngokufanelekileyo amanzi angaphezulu kunye negrisi ngaphandle kwentsalela.
Iingqwalasela zeNdawo yokuBilisa kwi-Isopropyl yoTywala kwiMisebenzi yeLabhoratri
Indawo yokubilisa ye-isopropyl alcohol ikwangumba obalulekileyo kwilabhoratri. Ngokomzekelo, xa usenza ukufudumeza okanye ukubuyiswa kwe-solvent, ukwazi indawo yokubilisa ye-isopropyl alcohol kunokunceda izazinzulu zikhethe iimeko ezifanelekileyo zokuphepha ukufudumala kunye nokunyuka kwe-solvent evaporation. Iqondo eliphantsi lokubilisa likwathetha ukuba i-isopropanol kufuneka igcinwe kwaye isetyenziswe ngokunyamekela ukukhusela ilahleko eguqukayo kwaye iqhutywe kwindawo enomoya ococekileyo ukuqinisekisa ukhuseleko.
Ukuqukumbela
Ukuqonda indawo yokubilisa ye-isopropanol ibalulekile ekusetyenzisweni kwayo kwishishini kunye neebhubhoratri. Ngokuqonda i-molecular structure kunye ne-hydrogen bonding ye-isopropanol, ukuziphatha kwayo phantsi kweemeko ezahlukeneyo kunokuqikelelwa kakuhle kwaye kulawulwe. Kwiinkqubo zoshishino, iimpawu zokubilisa ze-isopropanol zingasetyenziselwa ukwandisa ukusetyenziswa kwamandla kunye nokwandisa imveliso. Kwibhubhoratri, ukuqwalasela indawo yokubilisa ye-isopropanol iqinisekisa ukuqhuba kakuhle kweemvavanyo kunye nokhuseleko lwemisebenzi. Ngoko ke, indawo yokubilisa ye-isopropanol yiparameter ebalulekileyo engafanele ihoywe kwimveliso yeekhemikhali kunye nophando lwezesayensi.
