Uhlalutyo lwe-Ethyl Acetate Blalting Poil: IiPropathi eziSiseko kunye nezinto eziPhatha
I-Ethyl Acetate (i-EA) yinxalenye eqhelekileyo yezinto eziphilayo ngoluhlu olubanzi lwezicelo. Ihlala isetyenziswa njenge-solvent, i-incavoring kunye nesongezo sokutya, kwaye ithandwa ngenxa yokuzinza kwayo kunye nokukhuseleka kwayo. Ukuqonda iipropathi ezisisiseko kunye nezinto ezichaphazela inqaku lokubila le-ethyl acetate kubalulekile ukuba isetyenziswe kwimveliso yezamashishini.
Iipropathi ezisisiseko ze-Ethyl Acetate
I-Ethyl Acetate lulwelo olungenamibala kunye nesiqhamo-njengevumba elinevumba elimnandi. Inefomula ye-molecular cohh₈o₂ kunye nobunzima bemolekyuli ye-88.11 g / mol dis.Iings Inqaku lokubila lenza ukuba kube lula ukuphelisa ubushushu begumbi, kuyenza ilungele ukusetyenziswa kwimeko ezahlukeneyo zesicelo apho kufuneka ngokukhawuleza khona.
Izinto ezichaphazela indawo yokubila ye-ethyl ye-ocetate

Iziphumo zoxinzelelo lwangaphandle:

Indawo yokubila ye-ethyl i-ethyl inxulumene ngokusondeleyo nengcinezelo. Kwingcinezelo ye-themospic eqhelekileyo, indawo yokubila ye-Ethyl Acetate yi-77.1 ° C. Nangona kunjalo, njengoko uxinzelelo luyancipha, inqaku lokubila liyancipha ngokufanelekileyo. Le ndawo ibaluleke kakhulu kwizicelo zemizi-mveliso, ngakumbi i-distilaum distilang, apho indawo yokubila ye-Ethyl i-Ethyl inokuthi incitshiswe kakhulu, oko kuchaphazela ukusebenza ngokukuko nokucoca inkqubo.

Isiphumo sonyulo kunye nomxube:

Ukucoceka kwe-Ethyl i-ethyl inesiphumo kwindawo yayo yokubila. UChormoity of Silyl Acetate unendawo yokubila ebilayo enokutshintsha xa ixutywe nezinye iichemical okanye iikhemikhali. I-phenomenon ye-Azenoyotropy yemixube ngumzekelo oqhelekileyo, apho uluhlu oluthile lwe-Ethyl Acetate exutywe nenqaku lomxube, ebangela umxube wokuphuma kwiqondo lokushisa.

Unxibelelwano lwe-Intermolecular:

Unxibelelwano lwe-Intermolecular, njenge-hydrogen bound okanye iVan der imikhosi, ibuthathaka kwi-Ethyl Acetate kodwa isenempembelelo efihlakeleyo kwindawo yayo yokubila. Ngenxa yesakhiwo seqela le-Ethyl Acetate Molecule, i-Intermolecular Ver der imikhosi incinci, ikhokelela kwindawo esezantsi yokubila. Ngokwahlukileyo, izinto ezinamandla ombane owomeleleyo ngokuqhelekileyo anamanqaku aphezulu abilayo.

Indawo yokubila ye-Ethyl ye-Ethyl Acetate kumzi mveliso

I-Ethyl Acetate inendawo yokubila ye-77.1 C, ipropathi ekhokelele ekusebenziseni kwayo njengesinyibilikisi kwishishini lekhemikhali, ngakumbi ekuvelisweni kweepeyinti, iingubo kunye nemidinga. Inqaku layo elibilayo livumela ukukhutshwa ngokukhawuleza, ukubonelela ngokuthoba kunye nokukhululeka kokuphatha. Kumzi-mveliso wamachiza, i-Ethyl Acetate isetyenziselwa ukucocwa kunye nokucocwa kweendawo ezinomhlaba, njengoko indawo ebilayo enomgangatho ofanelekileyo ivumela ukwahlulwa okufanelekileyo kweendawo ekujoliswe kuzo kunye nokungcola.

Ukushwankathela

Ukuqonda indawo yokubila ye-ethyl ye-ethyl kunye nezinto eziphembelelayo kubalulekile kwimveliso kunye nesicelo kwishishini lekhemikhali. Ngokulawula ngokufanelekileyo uxinzelelo olufanelekileyo, ukulawula ubunyulu, kunye nokuthathela ingqalelo ukusebenzisana okungenantlonelo, ukusebenza kakuhle kwe-Ethyl Acetate ukusetyenziswa kunokuphumelela ngokufanelekileyo. Inyani yokuba i-Ethyl Acytate inendawo yokubila i-77.1 ° iyenza inyikima ebalulekileyo kwaye iphakathi kwizicelo ezininzi zemveliso.
