Kulo phepha, indawo yokubilisa ye-acetonitrile iya kuhlalutywa ngokubanzi, kwaye impembelelo yale parameter ekusebenzeni kweekhemikhali iya kuxutyushwa.
Indawo yokubilisa ye-acetonitrile kunye nezinto ezichaphazelayo
Indawo yokubilisa ye-acetonitrile idla ngokuba yi-81.6 ° C (malunga ne-179 ° F), kwaye eli qondo lokushisa libaluleke kakhulu kwi-distillation, ukulungiswa kunye nezinye iindlela zokwahlula kwiinkqubo zeekhemikhali. Indawo yokubilisa ye-acetonitrile ichaphazeleka kwizinto ezininzi, kubandakanywa uxinzelelo, ukucoceka, kunye nokuxuba kunye nezinye izinto. Ngokuqhelekileyo, indawo yokubilisa ye-acetonitrile igxininisekile phantsi koxinzelelo oluqhelekileyo lwe-atmospheric, kodwa ukuba uxinzelelo luyatshintsha, indawo yokubilisa iya kutshintsha. Ngokomzekelo, phantsi koxinzelelo oluncitshisiweyo, indawo yokubilisa ye-acetonitrile iyancipha, kwaye ngokuchaseneyo, phantsi kweemeko ezixinzelelekileyo, indawo yokubilisa iyanda. Olu phawu lwenza i-acetonitrile ibe nokwenzeka okubanzi kwesicelo phantsi kweemeko zenkqubo ezahlukeneyo.
Ukubaluleka kwendawo yokubilisa ye-acetonitrile kwizicelo zoshishino
Ukwazi indawo yokubilisa ye-acetonitrile lixabiso elibalulekileyo lokubhekisela ekuqulunqeni iimeko zokusebenza kweekhemikhali. Kwimveliso yoshishino, kudla ngokuyimfuneko ukwahlula imixube, kwaye indawo yokubilisa ye-acetonitrile yenza enye yezona zinto zilungileyo kwinkqubo yokubuyisela i-solvent. Ngokomzekelo, kuhlalutyo lwe-chromatography yolwelo, indawo yokubilisa efanelekileyo ye-acetonitrile iyenza ibe ngumphunga kwiqondo lobushushu elisezantsi, ngokufanelekileyo ukunqanda ukuthotywa kwe-thermal yesampulu. Kwi-synthetic chemistry, ukulawula ubushushu bokusabela kufutshane okanye ngaphantsi kwendawo yokubilisa ye-acetonitrile kunceda ukuqinisekisa ukhuseleko lokuphendula kunye nokucoceka kweemveliso.
Indlela yokusebenzisa indawo yokubilisa ye-acetonitrile ukwandisa inkqubo yokuvelisa
Ngokwazi nokuqonda indawo yokubilisa ye-acetonitrile, iinjineli zinokunyusa iinkqubo zokuvelisa ukuphucula ukusebenza kakuhle kunye nokunciphisa iindleko. Ngokomzekelo, kwinkqubo ye-distillation, indawo yokubilisa ye-acetonitrile ingasetyenziselwa njengesiseko esibalulekileyo sokubeka ukushisa okusebenzayo kwekholamu ye-distillation ukuqinisekisa ukusebenza kakuhle kokuhlukana. Ngokulungelelanisa uxinzelelo lwenkqubo yokutshintsha indawo yokubilisa ye-acetonitrile, kunokwenzeka ukufezekisa imisebenzi yokuvelisa eguquguqukayo phantsi kweemeko ezahlukeneyo zenkqubo. Le ndlela ayikwazi nje ukugcina amandla ngokufanelekileyo, kodwa iphinde iphucule ukhuseleko kunye nokuzinza komgca wemveliso yonke.
Isishwankathelo
Indawo yokubilisa ye-acetonitrile yiparameter yomzimba ebalulekileyo kwishishini lemichiza, elichaphazela ngokuthe ngqo ukuyila kunye nokuphunyezwa kwemisebenzi eyahlukeneyo yeekhemikhali. Ukuqala kwiimpawu ezisisiseko ze-acetonitrile, ukuqonda okunzulu kwezinto ezichaphazelayo kwindawo yokubilisa kunye nendima yayo kwizicelo zoshishino kunokunceda iinjineli ziphucule ngcono inkqubo yokuvelisa, ukuphucula umgangatho wemveliso kunye nokufezekisa injongo yophuhliso oluzinzileyo. Ngokuqonda ngokupheleleyo kunye nokusebenzisa indawo yokubilisa ye-acetonitrile, iinkampani zeekhemikhali ziyakwazi ukuthatha inzuzo yokhuphiswano olunzima lwemarike.
