Uhlalutyo oluBanzi lwe-Acetonitrile Density
I-Acetonitrile, njenge-solvent ebalulekileyo yeekhemikhali, isetyenziswa ngokubanzi kwiindlela ezahlukeneyo zemichiza kunye nezicelo zemizi-mveliso ngenxa yeempawu zayo ezizodwa ze-physicochemical. Kule nqaku, siza kuhlalutya ipropati ephambili ye-Acetonitrile density ngokweenkcukacha ukukunceda uqonde ngcono kwaye usebenzise le khompawundi.
Iimpawu ezisisiseko ze-Acetonitrile
I-Acetonitrile (ifomula yeekhemikhali: C₂H₃N) yinto engamanzi engenambala kunye nokuguquguquka okuphezulu kunye nokunyibilika okulungileyo. Isetyenziswa kakhulu kumayeza, kwi-agrochemicals, iziqholo kunye neepeyinti. I-acetonitrile ayisiyonto ebalulekileyo kuphela ephakathi kwi-organic synthesis, kodwa ikwasoloko isetyenziswa njengesinyibilikisi kwilabhoratri. Ke ngoko, ukuqonda iipropathi ezibonakalayo ze-acetonitrile, ngakumbi ukuxinana, kubalulekile kuphando lwezenzululwazi kunye nemveliso yeshishini.
Inkcazo kunye nomlinganiselo we-Acetonitrile Density
Uxinaniso ludla ngokubhekisa kubunzima ngeyunithi yevolumu yento, kwaye intetho ithi ρ = ​​m/V, apho u-ρ bubuninzi, m bubunzima, kunye no-V ngumthamo. Kwi-acetonitrile, ukuxinana kwayo lixabiso elizinzile kwiqondo lokushisa elithile kunye noxinzelelo. Kwiimeko eziqhelekileyo (25 ° C, 1 atm), ubuninzi be-acetonitrile bumalunga ne-0.786 g/cm³. Kufuneka kuqatshelwe ukuba ubuninzi be-acetonitrile buguquka ngobushushu. Ngoko ke, kwizicelo eziphathekayo, ukuxinana kufuneka kulungiswe ngokwemiqathango ethile yokusebenza.
Impembelelo yobushushu kubuninzi be-acetonitrile
Ubuninzi be-acetonitrile buchatshazelwa kakhulu bubushushu, kwaye ubuninzi be-acetonitrile buyancipha njengoko ubushushu buphakama. Oku kubangelwa kukuba xa iqondo lobushushu linyuka, intshukumo yemolekyuli iba namandla kwaye umgama phakathi kweemolekyuli uyanda, nto leyo ekhokelela ekwandeni komthamo kuze ngaloo ndlela kunciphe ukuxinana. Ke ngoko, isiphumo sobushushu kuxinaniso lwe-acetonitrile kufuneka ithathelwe ingqalelo kwiimeko ezibandakanya i-metrology echanekileyo okanye ukusabela, ngakumbi ngexesha lokusabela kweekhemikhali kunye nokwahlula. Ngokomzekelo, xa usebenzisa i-acetonitrile kumaqondo okushisa aphezulu, ubuninzi bayo kufuneka bulungiswe ukuze kuqinisekiswe ukuchaneka kwiinkqubo zovavanyo okanye zokuvelisa.
Iziphumo zeAcetonitrile Density kwizicelo
Ubuninzi be-acetonitrile buchaphazela ukuziphatha kwayo kwiinkqubo ezahlukeneyo zokunyibilikisa. Njengento enyibilikayo, i-acetonitrile inoxinano olusezantsi kunezinye izinyibilikisi ezininzi eziphilayo, eyivumela ukuba ibonise indlela yokumaleko eyahlukileyo kwimixube. Kwi-extraction ye-liquid-liquid kunye ne-chromatography, ubuninzi be-acetonitrile bunempembelelo ebalulekileyo kwi-coefficient yokwahlula kunye nokuhlukana. Ngoko ke, xa ukhetha i-acetonitrile njenge-solvent, umphumo wokuxinana kwayo kuyo yonke inkqubo yeekhemikhali kufuneka iqwalaselwe ngokupheleleyo ukuze kuphunyezwe iziphumo ezilungileyo.
Isishwankathelo
Ngohlalutyo olubanzi lokuxinana kwe-acetonitrile, siyaqonda ukuba ukuxinana yinto ebalulekileyo echaphazela ukusetyenziswa kwe-acetonitrile. Ukuqonda ukuxinana kwe-acetonitrile kunye nomthetho wayo wokutshintsha kunye nobushushu kungasinceda ukuba silawule ngcono kwaye sisebenzise inkqubo yokuvelisa imichiza. Kuphando lwexesha elizayo kunye nokusetyenziswa, kuyafaneleka ukuqwalasela ubuninzi be-acetonitrile njengepharamitha ephambili yokuqinisekisa ukuchaneka kweemvavanyo kunye nomgangatho weemveliso.
