Ukusetyenziswa okuphambili kwe-n-hexane
I-N-hexane yinto efanelekileyo ye-solvent ye-organic non-toxic, isetyenziswa ngokubanzi kwi-oyile ye-oyile yemifuno, i-butyl, i-butadiene irabha ye-organic synthesis, i-propylene, i-olefin polymerization, i-pharmaceutical intermediates, i-peyinti yepeyinti, kunye nokucoca indawo yentsimbi yezixhobo zomatshini.

Uphuhliso kunye nokusetyenziswa okuphambili kwe-n-hexane
Imakethi ephambili ye-n-hexane isetyenziswa kwishishini le-oyile yemifuno, elibalelwa ngaphezulu kwe-60% yexabiso lilonke le-n-hexane. Uninzi lwezicelo eziseleyo zikumashishini erabha kunye neekhemikhali.

Kwangoko ngeminyaka yoo-1960, amazwe aseNtshona aphuhlileyo anje ngeYurophu neUnited States aye akhuthaza ngokubanzi “indlela yokucoca” kwimveliso yeoli yemifuno. Ukongeza kokutsalwa kwe-oyile encinci, i-oyile etyiwayo yehlabathi eveliswe "yindlela yokucoca" ithathe i-95% yentengiso. Okwangoku, kwimveliso ye-oyile etyiwayo kumazwe ngamazwe, i-n-hexane yeyona nto iphambili yokunyibilikisa inkqubo yokuvelisa i-oyile etyiwayo. Ewe, inani elincinci leenkampani zeoyile eJapan naseMzantsi Korea zisebenzisa i-isohexane njenge-solvent extraction.
Ukusukela ekupheleni kweminyaka yoo-1980, iChina yaqala ukukhuthaza ngamandla ukusetyenziswa kwe-n-hexane njengesinyibilikisi se-oyile yemifuno.
Iimpawu zenkqubo ye-hexane leaching: Uluhlu lwe-hexane distillation lufutshane, i-solvent kunye nezinto ezinobungozi ziguquguquka ngokucokisekileyo, izondlo ze-oyile yemifuno azitshatyalaliswa ngubushushu obuphezulu, ukhuseleko lweoli edliwayo luyaphuculwa, kwaye ukusetyenziswa kwe-solvent ephantsi, kuphantsi. intsalela, isivuno esiphezulu se-oyile, kulula kwimveliso yesikali soshishino.
Okwangoku, iinkampani zasekhaya ezixhaswa ngemali ngamaTshayina kunye nendibaniselwano kunye neenkampani zabucala ezivelisa i-oyile etyiwayo ikakhulu zisebenzisa i-n-hexane njengesinyibilikisi se-leaching. Ezi nkampani zivelisa ngaphezu kwe-90% yeoli etyiwayo kwimarike yasekhaya.
Ukusetyenziswa kwe-n-hexane njenge-solvent oil extraction yimfuno engqongqo karhulumente kwishishini lokulungisa i-oyile etyiwayo kunye nemigangatho yomgangatho wemveliso. Ke ngoko, i-n-hexane iye yaba yimveliso ye-solvent esetyenziswa ngokuqhelekileyo kwi-oyile etyiwayo, ekwayi-hexane yasekhaya neyangaphandle kwiminyaka yakutshanje. Ngaphezulu kweNombolo ye-6 yeoli ye-solvent, i-butane kunye nezinye izinyibilikisi ziye zaba zezona ntlobo zibalulekileyo ze-oyile yemifuno ye-leaching solvent.
Enye ingongoma kukuba kwishishini lokutsalwa kwe-oyile yemifuno, i-n-hexane inendima ekhethekileyo kunye nengenakubuyiselwa. I-N-hexane inesihloko esithi "ukumkani wokukhutshwa". Ukuza kuthi ga ngoku, akukho sisinyibilikisi esikwazileyo ukugqitha i-n-hexane ekutsalweni.
