Indawo yokubilisa yetoluene: ingqiqo kule khemikhali eqhelekileyo
I-Toluene, njengento esetyenziswa ngokubanzi kwi-organic compound kumashishini ekhemikhali, idlala indima ebalulekileyo kwiinkalo ezininzi kunye neempawu zayo ezizodwa. Indawo yokubilisa ye-toluene yiparameter ephambili efuna ingqalelo ekhethekileyo kwimveliso yezoshishino kunye nezicelo. Ukuqonda indawo yokubilisa ye-toluene akufundisanga kuphela ukugcinwa nokuthutha, kodwa kubalulekile kulawulo lobushushu ngexesha lokusabela kweekhemikhali ezahlukeneyo.
Isishwankathelo seempawu ezisisiseko kunye nendawo yokubilisa ye-toluene
I-Toluene lulwelo olungenambala, olunevumba elimnandi kunye nefomula yemichiza ethi C₇H₈. Ifumaneka ngokubanzi kwiipeyinti, iingubo, i-thinners kunye ne-adhesives kwaye isetyenziswa ngokuqhelekileyo njenge-solvent ye-industrial. Kuxinzelelo lwe-atmospheric, indawo yokubila ye-toluene yi-110.6°C. Le ndawo yokubilisa isezantsi kakhulu ivumela itoluene ukuba ibe ngumphunga lula kwiqondo lobushushu begumbi, ngoko ke ingqwalasela eyodwa kufuneka ihlawulwe kukuguquguquka kwayo kunye neengozi zomphunga ezinokubakho ngexesha lokusebenza.
Izinto ezichaphazela indawo yokubilisa ye-toluene
Nangona indawo yokubilisa ye-toluene yi-110.6 ° C kuxinzelelo lwe-atmospheric, le parameter inokuchaphazeleka ngezinto ezahlukeneyo kwizicelo eziphathekayo. Ngokomzekelo, utshintsho kuxinzelelo lunokuchaphazela ngokuthe ngqo indawo yokubilisa ye-toluene. Ngokomthetho wegesi, indawo yokubilisa yolwelo iphakama xa uxinzelelo lukhula; ngokuchaseneyo, iyawa xa uxinzelelo luyancipha. Le nto isetyenziswa ngokubanzi kwi-industrial distillation kunye neenkqubo zokulungisa ukunyusa ukusetyenziswa kwamandla kunye nesivuno kwinkqubo yokwahlula.
Ubunyulu bukwayenye yezinto ezibalulekileyo ezichaphazela indawo yokubilisa yetoluene. Kwimveliso yemizi-mveliso, i-toluene ihlala iqulethe ezinye izinto ezingcolileyo, ubukho bayo obunokukhokelela ekutshintsheni okuncinci kwindawo yokubilisa ye-toluene. Ngoko ke, ukuqonda kunye nokulawula ukucoceka kwe-toluene kubalulekile ekufumaneni ngokuchanekileyo indawo yayo yokubilisa.
Indawo yokubilisa yeToluene kwishishini
Kwimveliso yeekhemikhali, indawo yokubilisa ye-toluene isetyenziswa ngokuqhelekileyo ukumisela ikhefu lobushushu phakathi kokuphuma komphunga kunye nokudibanisa, okubaluleke kakhulu kwiinkqubo zokwahlula ezifana ne-distillation kunye nokulungiswa. Ngokomzekelo, kwishishini le-petrochemical, i-toluene isoloko isetyenziselwa ukuveliswa kweekhemikhali ezibalulekileyo ezifana ne-benzene, i-methanol kunye ne-xylene. Ngokulawula ubushushu kwi-reactor ukwenzela ukuba i-toluene iphuphe kwaye idibanise kwiqondo lokushisa elifanelekileyo, ukukhetha kunye nesivuno sokusabela kunokuphuculwa.
Ukwazi indawo yokubilisa ye-toluene kubalulekile ekugcinweni kwayo okukhuselekileyo kunye nokuthutha. Ngenxa yokuba i-toluene iguquguqukayo kwaye inokutsha, kufuneka igcinwe kwindawo ephantsi kweqondo lokushisa ngexesha lokugcinwa, kwaye ukudibanisa ne-oxidising agents kunye nezinye izinto ezinobungozi kufuneka kugwenywe ukukhusela ukuqhuma okanye izingozi zomlilo.
Isishwankathelo
I-Toluene njengento ebalulekileyo yeekhemikhali, indawo yokubilisa ye-toluene yipharamitha ephambili kwisicelo sayo soshishino. Ngokufumana ukuqonda okunzulu kwendawo yokubilisa ye-toluene kunye neempembelelo zayo ezichaphazelayo, ukuziphatha kwayo kwinkqubo yokuvelisa inokuqonda kakuhle kwaye iinkqubo ezifanelekileyo zinokuphuculwa ukwenzela ukuphucula imveliso kunye nokhuseleko.
