Ubuninzi be-Isopropanol: Ukuqonda kunye nokuSetyenziswa kwayo kwiShishini leMichiza
I-Isopropanol, eyaziwa ngokuba yi-isopropyl alcohol okanye i-IPA, yinto eqhelekileyo ye-organic compound esetyenziselwa uluhlu olubanzi lweekhemikhali, amayeza kunye ne-cosmetic applications. Kweli nqaku, siza kujonga ngakumbi isihloko soxinaniso lwe-isopropanol ukukunceda uqonde ngokupheleleyo le propati ebonakalayo kunye nokubaluleka kwayo kwizicelo zehlabathi zangempela.
Yintoni i-Isopropyl Alcohol Density?
Ubuninzi be-isopropyl alcohol bubunzima be-isopropyl alcohol ngokomthamo weyunithi, budla ngokubonakaliswa ngeegram ngecubic centimeter (g/cm³). Uxinaniso luyiparameter ebalulekileyo kwiipropati ezibonakalayo zolwelo, oluchatshazelwa ngubushushu kunye noxinzelelo. Ngaphantsi kweemeko eziqhelekileyo (20 ° C, 1 atm), ubuninzi be-isopropanol malunga ne-0.785 g / cm³. Eli xabiso linokwahluka ngokweqondo lobushushu, ngoko ke kubalulekile ukuqonda kunye nokulungelelanisa ukuxinana kwe-isopropyl yotywala kwiimeko ezahlukeneyo zesicelo.
Ukubaluleka kwe-Isopropyl Alcohol Density
Umlinganiselo ochanekileyo wokuxinana kwe-isopropyl alcohol ubalulekile kwimveliso yeekhemikhali kunye nokusetyenziswa. Uxinaniso aluchaphazeli kuphela umlinganiselo womxube, kodwa luhambelana ngokuthe ngqo nokusebenza kakuhle kwempendulo kunye nomgangatho wemveliso. Ngokomzekelo, ekuphenduleni kweekhemikhali, ubuninzi be-isopropanol bunokuchaphazela i-viscosity yesisombululo, nto leyo echaphazela ukuhanjiswa kobuninzi kunye nemilinganiselo yokuphendula. Ukwazi ubuninzi be-isopropanol kunceda ukwandisa iiparitha zenkqubo kunye nokuqinisekisa ukuba ukusabela kuyenzeka phantsi kweemeko ezifanelekileyo.
Ukwahluka kobuninzi be-isopropanol kumaqondo okushisa ahlukeneyo
Njengoko bekutshiwo ngaphambili, ubuninzi be-isopropanol buyancipha njengoko ubushushu bukhula. Oku kungenxa yokuba ukunyuka kwamaqondo obushushu kubangela ukuba umgama phakathi kweemolekyuli unyuke, nto leyo enciphisa ukuxinana kolwelo. Ngokukodwa, kwi-20 ° C, i-isopropyl alcohol inoxinano lwe-0.785 g/cm³, ngelixa i-40 ° C, ubuninzi bayo buyehla malunga ne-0.774 g/cm³. Olu lwahluko lubaluleke kakhulu kumacandelo amachiza, amayeza kunye ne-biotechnology, apho ukuchaneka kwempahla ekrwada kubaluleke kakhulu kwaye utshintsho oluncinci lobuninzi lunokuba nefuthe elibalulekileyo kwimveliso yokugqibela.
Indlela yokulinganisa kunye nokulungelelanisa ubuninzi be-isopropyl alcohol
Ukulinganiswa kobuninzi be-isopropanol ngokuqhelekileyo kwenziwa ngokusebenzisa ibhotile ethile ye-gravity okanye i-densitometer yedijithali. Ngokwenza, ukulawulwa ngokuchanekileyo kobuninzi be-isopropanol kunokufezekiswa ngokulungelelanisa ubushushu okanye umxube wokuxuba. Kwiinkqubo zeekhemikhali ezifuna ukuchaneka okuphezulu, kuyinto eqhelekileyo ukubeka iliso ukuxinana ngexesha langempela kwaye wenze uhlengahlengiso ngokufanelekileyo. Oku akuphuculi imveliso kuphela, kodwa kuqinisekisa umgangatho wemveliso kunye nokuhambelana.
Isishwankathelo
Ubuninzi be-Isopropanol yiparameter yomzimba ephambili kwishishini lemichiza kwaye inoluhlu olubanzi lweempembelelo kwizicelo eziphathekayo. Ukuqonda ubuninzi be-isopropanol kunye neempawu zayo ezixhomekeke kwiqondo lokushisa kubalulekile ekuphuculeni inkqubo yokuvelisa kunye nokuphucula umgangatho wemveliso. Kwimveliso yeekhemikhali, ulawulo oluchanekileyo lwe-isopropanol density lunokuzisa ukusebenza kakuhle okuphezulu kunye nokusebenza kwemveliso okuzinzile. Ke ngoko, ukuqonda okunzulu kunye nokusetyenziswa okuchanekileyo kwale parameter kuya kuzisa iingenelo ezibalulekileyo zokukhuphisana kwiinkampani zeekhemikhali.
