Indawo yokuBilisa ye-Acetonitrile: Uhlalutyo lweePropati eziPhambili zeMzimba kunye nezicelo zoShishino
I-Acetonitrile yinto eqhelekileyo ye-organic compound kunye ne-chemical formula CH₃CN. Njenge-solvent ye-polar, i-acetonitrile isetyenziswa ngokubanzi kwiikhemikhali, amayeza, kunye namashishini amachiza. Ukuqonda iimpawu ezibonakalayo ze-acetonitrile, ngokukodwa indawo yokubilisa ye-acetonitrile, ibaluleke kakhulu ekusebenziseni kwayo. Kweli phepha, indawo yokubilisa ye-acetonitrile kunye nokubaluleka kwayo kwishishini kuya kuxoxwa ngokunzulu.
Iipropati eziSisiseko kunye neNdawo yokuBilisa ye-Acetonitrile
I-Acetonitrile ilulwelo olungenambala noluselubala kunye ne-polarity ephezulu, ngoko ke inokunyibilikisa iikhompawundi ezininzi ze-polar kunye nezingezo-polar. I-Acetonitrile ineqondo lokubilisa le-81.6 ° C, iqondo lokushisa elibaluleke kakhulu ekusebenzeni kweekhemikhali. Indawo yokubilisa ephantsi ye-acetonitrile yenza kube lula ukuphuphuma kwiqondo lobushushu begumbi kunye noxinzelelo, iyenze ilungele inani leenkqubo ezifuna ukomiswa ngokukhawuleza okanye ukuguquguquka.
Ukubaluleka kwendawo yokuBilisa ye-Acetonitrile kwizicelo zokunyibilikisa
I-Acetonitrile isetyenziswa ngokubanzi njenge-solvent kwi-chromatographic uhlalutyo olufana ne-High Performance Liquid Chromatography (HPLC). Kwi-HPLC, indawo yokubilisa ye-solvent ichaphazela ukhetho lwesigaba seselula kunye nomphumo wokuhlukana. Ngenxa yeqondo eliphantsi lokubilisa le-acetonitrile, linokuthi libe ngumphunga ngokukhawuleza, linciphise intsalela kunye nokuphucula ubunyulu besampulu. Ukusetyenziswa kwe-acetonitrile kwi-chemical synthesis kwakhona kuxhomekeke kwiimpawu zayo zamanqaku okubila. Ngokomzekelo, kwezinye iimpendulo zokwenziwa apho ubushushu bokusabela bufuna ukulawulwa, indawo yokubilisa ye-acetonitrile ingasetyenziswa njengesalathiso sokulungelelanisa iimeko zokusabela.
Ukulawulwa kwendawo yokubilisa ye-acetonitrile kwimveliso yezoshishino
Kwimveliso kunye nokugcinwa kwe-acetonitrile, ukulawula indawo yokubilisa ye-acetonitrile kubalulekile. Ekubeni i-acetonitrile ine-volatility ephezulu, ulawulo olungqongqo lobushushu luyafuneka ngexesha lenkqubo yokuvelisa ukuthintela ukuvela kwayo okugqithisileyo, okunokuthi kuchaphazele isivuno kunye nomgangatho. Xa ugcina i-acetonitrile, ngokuqhelekileyo kufuneka ibe kwindawo yokushisa ephantsi okanye evaliweyo ukuze kuncitshiswe ilahleko eguquguqukayo ye-acetonitrile kunye nokuqinisekisa ukhuseleko.
Ukhuseleko kunye nokuqwalaselwa kokusingqongileyo kwindawo yokubilisa ye-acetonitrile
Ukuguquguquka kwe-acetonitrile kwenza inqaku layo lokubilisa libe yinto ebalulekileyo ekucingeni ukhuseleko kunye nokusingqongileyo. Xa uphatha kwaye usebenzisa i-acetonitrile, ukuguquguquka kwayo kufuneka kuthathelwe ingqalelo ukukhusela i-inhalation yoxinzelelo oluphezulu lwe-acetonitrile vapour. Ulwazi lwendawo yokubilisa ye-acetonitrile lunokunceda ekuphuhliseni amaqhinga okulawula ukukhutshwa kwe-volatile organic compound (VOC) ukunciphisa iimpembelelo zokusingqongileyo ngexesha lokucocwa kwenkunkuma kwimizi-mveliso.
Isishwankathelo
Ulwazi lwendawo yokubilisa ye-acetonitrile lubalulekile kwisicelo sayo soshishino. Ingaba kwinkqubo yokuvelisa, ukugcinwa okanye ukusetyenziswa, indawo yokubilisa ye-acetonitrile ichaphazela ngokuthe ngqo ukhuseleko, ukusebenza kakuhle kunye nokukhuselwa kokusingqongileyo komsebenzi. Ngoko ke, kwishishini lemichiza, ukubeka ingqalelo kwindawo yokubilisa ye-acetonitrile yenye yezitshixo zokuqinisekisa ukuhamba kakuhle kweenkqubo.
