Indawo yokubilisa ye-dichloromethane: ulwazi kunye nokusetyenziswa
I-Dichloromethane, enefomula yemichiza ethi CH₂Cl₂, lulwelo olungenambala, olunuka kamnandi olusetyenziswa kakhulu kwimizi-mveliso nakwiilabhoratri. Njenge-solvent ebalulekileyo yezinto eziphilayo, idlala indima ephambili kwiinkqubo ezininzi zeekhemikhali ngenxa yeempawu zayo ezizodwa. Kweli phepha, siza kujonga ngokunzulu kwindawo yokubilisa ye-methylene chloride kwaye sihlalutye ukubaluleka kwayo kwizicelo ezisebenzayo.
Isishwankathelo seNdawo yokuBilisa yeMethylene Chloride
I-Methylene chloride ineqondo lokubila elingu-39.6°C. Le ndawo yokubilisa yobushushu obuphantsi iyenza iguquguquke kakhulu kwiqondo lobushushu begumbi. IDichloromethane inendawo yokubila esezantsi kakhulu kunezinye izinyibilikisi ezininzi eziphilayo, ngoko ke ihlala ikhethwa kwiinkqubo ezifuna ukuvela komphunga ngokukhawuleza kwezinyibilikisi. Eli nqanaba lokubilisa eliphantsi lenza i-methylene chloride igqwese kakhulu ekubuyiseleni i-solvent kunye neenkqubo zokomisa, okuvumela ukuba u-evaporation ugqitywe ngokufanelekileyo.
Izinto ezichaphazela indawo yokubilisa ye-methylene chloride
Nangona i-methylene chloride inendawo yokubilisa ye-39.6 ° C, eli qondo lokushisa alitshintshi. Indawo yokubilisa inokuchaphazeleka kwizinto ezininzi, ezifana noxinzelelo lwe-atmospheric, ukucoceka kunye namanye amacandelo kumxube. Kuxinzelelo oluqhelekileyo lwe-atmospheric, indawo yokubilisa ye-methylene chloride izinzile. Xa uxinzelelo lwe-atmospheric lutshintsha, umzekelo kwiindawo eziphakamileyo, indawo yokubilisa iyancipha kancane. Ukucoceka kwe-methylene chloride nayo ichaphazela indawo yayo yokubilisa, kwaye ubukho bokungcola bunokubangela ukuguquguquka okuncinci kwindawo yokubilisa.
Indawo yokubilisa yeDichloromethane kwizicelo zamashishini
I-Dichloromethane isetyenziswa ngokubanzi kwishishini ngenxa yendawo yokubilisa ephantsi, ngakumbi kwiinkqubo zokukhutshwa kunye nokucoca. Ngenxa yokukwazi ukukhupha ngokukhawuleza kunye nokunyibilika kwayo okulungileyo, i-methylene chloride isetyenziswa ngokuqhelekileyo kwiinkqubo zokukhutshwa kweoli, i-resin kunye nezinye izinto eziphilayo. Kwishishini lamachiza, lisetyenziswa njenge-solvent ukukhupha izithako ezisebenzayo kunye nokulungiswa kwemveliso yokugqibela ukususa ngokukhawuleza i-solvent eseleyo ukuqinisekisa ukucoceka kwemveliso.
Isishwankathelo
I-Methylene chloride inendawo yokubilisa ye-39.6 ° C, ipropati eyenza i-solvent eyimfuneko kwishishini lemichiza. Ukuqonda kunye nokuqonda iimpawu zokubilisa ze-methylene chloride kunokunceda abaqeqeshi beekhemikhali bamashishini ukuba baqulunqe ngcono kwaye basebenzise iinkqubo zokuvelisa. Kwizicelo ezisebenzayo, ukusebenzisa indawo yokubilisa ye-methylene chloride ngokubambisana nokutshintsha kweemeko zokusingqongileyo kunye nokucoceka kwezinto kunokuphucula kakhulu inkqubo yokusebenza kunye nomgangatho wemveliso.
