Ubuninzi be-dichloromethane: Ukujongwa nzulu kwesi sakhiwo sibalulekileyo somzimba
I-Methylene chloride (ifomula yeekhemikhali: CH₂Cl₂), ekwabizwa ngokuba yikloromethane, lulwelo olungenambala, olunuka kamnandi olusetyenziswa kakhulu kwishishini lemichiza, ngakumbi njengesinyibilikisi. Ukuqonda ipropati ebonakalayo yoxinaniso lwe-methylene chloride kubalulekile ekusebenziseni kwayo kwishishini. Kule nqaku, siza kuhlolisisa iimpawu zoxinaniso lwe-methylene chloride ngokubanzi kunye nendlela le propati echaphazela ngayo ukusetyenziswa kwayo kwiinkqubo zeekhemikhali.
Yintoni ubuninzi be-methylene chloride?
Uxinaniso lumlinganiselo wobunzima bento kumthamo wayo kwaye yiparameter yomzimba ebalulekileyo yokubonisa into. Ubuninzi be-methylene chloride bumalunga ne-1.33 g/cm³ (ngama-20°C). Eli xabiso loxinaniso libonisa ukuba i-methylene chloride ixinene kancinci kunamanzi (1 g/cm³) kwiqondo lobushushu elifanayo, oku kuthetha ukuba inzima kancinci kunamanzi. Le propati yoxinaniso ivumela i-methylene chloride ukuba ibonise ukuziphatha okuyingqayizivele kwizicelo ezininzi, umzekelo kwiinkqubo zokwahlula ulwelo-ulwelo, apho ngokuqhelekileyo ibekwe ngaphantsi komgangatho wamanzi.
Impembelelo yobushushu kubuninzi be-methylene chloride
Ubuninzi be-methylene chloride buhluka ngobushushu. Ngokuqhelekileyo, ubuninzi be-methylene chloride buyancipha njengoko ubushushu bukhula. Oku kungenxa yokwandiswa kwezithuba zeemolekyuli ngenxa yokushisa okuphezulu, okunciphisa umxholo wobunzima kwiyunithi nganye. Umzekelo, kumaqondo obushushu aphezulu, ubuninzi be-methylene chloride bunokwehla ngaphantsi kwe-1.30 g/cm³. Olu tshintsho lubalulekile kwiinkqubo zeekhemikhali apho ukulawulwa ngokuchanekileyo kweepropati ze-solvent kuyadingeka, njengeenkqubo zokutsalwa okanye zokwahlula, apho utshintsho oluncinci kwi-density lunokuchaphazela kakhulu iziphumo zokusebenza. Ukuxhomekeka kobushushu boxinzelelo kufuneka kuqwalaselwe ngononophelo kuyilo lweenkqubo ezibandakanya i-methylene chloride.
Impembelelo yoxinaniso lwe-dichloromethane kwizicelo zayo
Ubuninzi beDichloromethane bunempembelelo ethe ngqo kwizicelo zayo ezininzi kwishishini. Ngenxa yobuninzi bayo obuphezulu, i-dichloromethane yi-solvent efanelekileyo kwi-extraction ye-liquid-liquid kwaye ifaneleke ngokukodwa ukuhlukana kwezinto eziphilayo ezingenakulinganiswa namanzi. Ikwasebenza njengesinyibilikisi esigqwesileyo kwimveliso yepeyinti, amayeza, kunye neemveliso zemichiza. Ubuninzi be-methylene chloride buyenza ibonise iimpawu ezizodwa ngokubhekiselele kwi-solubility yegesi kunye noxinzelelo lomphunga, kwaye isetyenziswa ngokubanzi kwii-agent ezikhupha amagwebu, iipeyinti zepeyinti kunye nezinye izicelo.
Isishwankathelo
Ipropathi ebonakalayo ye-dichloromethane density idlala indima ebalulekileyo kwishishini lemichiza. Ukuqonda kunye nolwazi lwale parameter akuncedi kuphela ukunyusa ukusebenza kwezoshishino kodwa kwakhona kuqinisekisa ukuba iziphumo ezilungileyo zenkqubo zifezekiswa kwiimeko ezahlukeneyo zokushisa. Ngokuhlalutya kweli phepha, kukholelwa ukuba umfundi uya kuba nako ukuqonda ngokunzulu ubuninzi be-dichloromethane kunye nokubaluleka kwayo kwizicelo zoshishino.
