Uhlalutyo olunzulu lwendawo yokubilisa yetoluene
I-Toluene yinto eqhelekileyo ye-organic compound kunye noluhlu olubanzi lwezicelo kwishishini lemichiza. Ukuqonda iimpawu ezibonakalayo ze-toluene, ngokukodwa indawo yayo yokubilisa, kubalulekile kuyilo kunye nokusebenza kweenkqubo zokuvelisa. Kule nqaku, siza kuhlolisisa ngokubanzi ulwazi lwendawo yokubilisa ye-toluene kwaye sihlalutye ukubaluleka kwayo kwishishini kunye nezinto ezichaphazelayo.
Iimpawu ezisisiseko ze-toluene kunye nendawo yokubilisa
I-Toluene (i-Toluene) yi-methyl ethatha indawo ye-benzene, kunye ne-chemical formula C7H8. Lulwelo olungenambala olucacileyo olunevumba elimnandi. Itoluene ineqondo lokubila elimalunga ne-110.6°C (231.1°F), apho iqondo lobushushu litshintsha ukusuka kulwelo ukuya kwirhasi. Indawo yokubilisa ye-toluene ibalulekile kwizicelo zamashishini kuba ichaphazela ngokuthe ngqo i-distillation, ukwahlukana, kunye nezinye iinkqubo zeekhemikhali ezibandakanya utshintsho lwesigaba.
Indawo yokubilisa yeToluene kwizicelo zoshishino
I-Toluene isetyenziswa ngokuqhelekileyo njenge-solvent, i-reaction material, kunye ne-intermediate in chemical synthesis in petrochemical and organic synthesis. I-toluene inendawo yokubila ephezulu kancinane kunebenzene, ngoko ke itoluene kunye nezinye iikhompawundi ezifanayo zinokwahlulwa ngokufanelekileyo ngokulawula ngokuchanekileyo ubushushu xa imixube ifuna ukwahlulwa. Oku kubalulekile kwimveliso yeemveliso ezineemfuno eziphezulu zokucoceka. Indawo yokubilisa ye-toluene nayo idlala indima ekuphuculeni ukusetyenziswa kwamandla kwiinkqubo zoshishino. Ngokomzekelo, ngexesha le-distillation, ukwazi indawo yokubilisa ye-toluene kunokunceda ukugqiba iiparamitha zokuyila izixhobo zokufudumeza, ngaloo ndlela ukunciphisa iindleko zamandla.
Izinto ezichaphazela indawo yokubilisa ye-toluene
Nangona i-toluene ineqondo lokubilisa eliqhelekileyo le-110.6 ° C, ekusebenzeni, utshintsho kwixinzelelo lwe-ambient lunokubangela ukuguquguquka kwindawo yokubilisa. Kwiindawo eziphantsi koxinzelelo, indawo yokubilisa ye-toluene iyancipha, ngelixa kwiindawo ezinoxinzelelo oluphezulu, indawo yokubilisa iyanda. Ngoko ke, umphumo woxinzelelo kwindawo yokubilisa kufuneka ithathelwe ingqalelo xa uyila kunye neenkqubo zokusebenza ezibandakanya i-toluene. Indawo yokubilisa ye-toluene iyatshintsha kwakhona xa ixutywe nezinye iikhompawundi, ngakumbi xa kwenziwa i-azeotropes, enokuthi ibe namanqaku abilayo ahluke kakhulu kwi-toluene ecocekileyo.
Indawo yokuBilisa yeToluene kunye nokuPhathwa ngokuKhuselekileyo
Kwimisebenzi yoshishino ebandakanya i-toluene, ukwazi nokuqonda indawo yokubilisa ye-toluene kubalulekile ekusebenzeni okukhuselekileyo. Njengoko i-toluene ilulwelo olunokutsha, xa amaqondo obushushu esondela okanye edlula iqondo lokubilisa, ukuveliswa komphunga kwanda kakhulu, nto leyo eyandisa ingozi yokuqhuma nomlilo. Ngoko ke, xa uphethe i-toluene, iqondo lokushisa kufuneka lilawulwe ngokungqongqo kwaye amanyathelo afanelekileyo okukhusela umlilo kunye nokuqhuma kufuneka athathwe ukuze kuqinisekiswe imveliso ekhuselekileyo.
Ukuqukumbela
Indawo yokubilisa ye-toluene yiparameter yomzimba ebalulekileyo engakwazi ukunyanzeliswa kwishishini lemichiza, elingachaphazeli nje ukusebenza kakuhle kwemveliso, kodwa linxulumene nokhuseleko lwenkqubo. Ngokuqonda ngokunzulu indawo yokubilisa ye-toluene kunye nezinto ezichaphazelayo, inkqubo yeekhemikhali inokuthi yenziwe ngcono kwaye iphuculwe ukuze kuphuculwe umgangatho wemveliso kunye nokhuseleko lwemveliso. Ngokwenza umsebenzi, ukulawulwa ngokuchanekileyo kwendawo yokubilisa ye-toluene ngokudibanisa noxinzelelo, iipropati zomxube kunye nezinye izinto ziya kunceda ukufezekisa inkqubo yokuvelisa ezinzile kunye nokusebenza kakuhle.
