Ubuninzi be-Ethyl Acetate: Uhlalutyo oluBanzi kunye neSicelo esiSebenzayo
I-Ethyl Acetate yinto eqhelekileyo ye-solvent esetyenziswa kwiindidi ezahlukeneyo zeendawo zoshishino kunye nebhubhoratri. Ukuqonda ubuninzi be-Ethyl Acetate akubalulekanga nje kuphela ukuveliswa kweekhemikhali, kodwa kunceda ukunyusa ukusebenza kakuhle kwayo kwiimeko ezahlukeneyo zokusetyenziswa. Kweli nqaku, siza kuxubusha ukuxinana kwe-ethyl acetate kunye nezinto ezibandakanyekayo ukukunceda ukuba uqonde ngcono le propati ebalulekileyo yomzimba.
Inkcazo yoxinano lwe-Ethyl Acetate
Ubuninzi be-ethyl acetate bubunzima beyunithi nganye ye-ethyl acetate kwiqondo lokushisa elinikeziweyo kunye noxinzelelo. Ngokwesiqhelo, ukuxinana kulinganiswa nge-g/cm³ (iigram nge-cubic centimeter) okanye i-kg/m³ (iikhilogram nge-cubic mitha). Kwabo basebenza kwishishini lemichiza, idatha echanekileyo malunga nokuxinana kwe-ethyl acetate inokunceda ukubala ngokuchanekileyo ukusetyenziswa kwezinto eziphathekayo, ukwandisa iinkqubo kunye nokuqinisekisa umgangatho wemveliso.
Amaxabiso athile oxinaniso lwe-ethyl acetate
Ngaphantsi kweemeko eziqhelekileyo (20 ° C, 1 atmosphere), ubuninzi be-ethyl acetate bumalunga ne-0.902 g/cm³. Eli xabiso lithetha ukuba i-cubic centimeter nganye ye-ethyl acetate inobunzima obumalunga ne-0.902 grams. Kubalulekile ukuqaphela ukuba ukuxinana kuyahluka kunye nobushushu. Njengoko iqondo lokushisa linyuka, umthamo we-liquid udla ngokukhula, okubangela ubuninzi obuphantsi. Ngoko ke, umphumo wokutshintsha kweqondo lokushisa kwindawo yokusebenza kwi-ethyl acetate kufuneka ithathelwe ingqalelo xa wenza izibalo ezichanekileyo.
Izinto ezichaphazela ukuxinana kwe-ethyl acetate
Ubushushu: Ubushushu yenye yezinto eziphambili ezichaphazela ukuxinana kwe-ethyl acetate. Njengoko iqondo lokushisa liphakama, ukunyakaza kwe-molecular ye-liquid kuqinisa kwaye umthamo uyanda, obangela ukuhla kobuninzi. Ngokuqhelekileyo kwimveliso yezoshishino, ubuninzi be-ethyl acetate bulungiswa ngokuhambelana nokutshintsha kweqondo lokushisa ukuqinisekisa ukuchaneka kokulinganisa.

Ubunyulu: Ubuninzi be-ethyl acetate bukwachatshazelwa bubunyulu bayo. Ukuba i-ethyl acetate ixutywe kunye nezinye izinto ezingcolileyo, ezifana namanzi okanye ezinye i-solvents, ubuninzi bungatshintsha. Ngoko ke, ukusebenzisa ubunyulu be-ethyl acetate akuqinisekisi kuphela ukuzinza kwenkqubo, kodwa kukhokelela kwidatha ethembekileyo yoxinaniso.

Uxinzelelo: Nangona uxinzelelo lunempembelelo encinci kubuninzi bolwelo, phantsi kweemeko zoxinzelelo oluphezulu uxinano luyakwenyuka kancinci. Oku kufuneka kuthathelwe ingqalelo kwizicelo zoxinzelelo oluphezulu lwemizi-mveliso, ngakumbi apho imisebenzi echanekileyo ephezulu ibandakanyekayo.

Ukusetyenziswa okusebenzayo kwe-ethyl acetate density
Kwishishini lemichiza, ubuninzi be-ethyl acetate inezicelo ezibalulekileyo kwiindawo ezininzi. Ekuqulunqweni kweemveliso ezifana neengubo kunye ne-adhesives, idatha yoxinaniso sisiseko sokumisela umlinganiselo wamacandelo. Kwiinkqubo zokugcina kunye nokuthutha, ulwazi loxinaniso lunceda ukubala umthamo wokugcina kunye neendleko zokuthutha izinto. Kwiinkqubo zokwahlula ezifana ne-distillation, ubuninzi buyiparameter ebalulekileyo yokumisela ukuphumelela kokuhlukana kwemixube yezinto ezifanayo.
Ukuqukumbela.
Ukuqonda ubuninzi be-ethyl acetate kunye nezinto ezichaphazelayo kubalulekile kuyo yonke imiba yokuveliswa kweekhemikhali. Ngokubamba imiphumo yokushisa, ukucoceka kunye noxinzelelo kubuninzi be-ethyl acetate, abaqeqeshi beekhemikhali banokulawula ngcono inkqubo yokuvelisa kunye nokuphucula umgangatho wemveliso. Siyathemba ukuba eli nqaku liza kukunceda uqonde ngcono kwaye usebenzise ipropathi engundoqo ye-ethyl acetate kwizicelo ezibonakalayo.
