Amakhandlela, isixhobo sokukhanyisa imihla ngemihla, esenziwa ikakhulu kwiparafini, kumaxesha amandulo, ngokuqhelekileyo ayenziwe ngegrisi yezilwanyana. Inokutshisa ukunika ukukhanya. Ukongeza, amakhandlela asetyenziselwa iinjongo ezininzi: kumatheko emihla yokuzalwa, kwimibhiyozo yenkolo, ukulila kwamaqela, kunye nemitshato kunye nemingcwabo. Kwimisebenzi yoncwadi kunye nobugcisa, amakhandlela anentsingiselo engokomfanekiso yombingelelo nokuzinikela.
Kumaxesha anamhlanje, kukholelwa ngokubanzi ukuba amakhandlela avela kwiitotshi zamaxesha amandulo. abantu bamandulo babepeyinta amanqatha okanye iwax kumaxolo okanye iitshiphu zamaplanga baze bazibophe kunye ukwenza iitotshi zokukhanyisa. Kwakhona kuthiwa kwi-pre-Qin kunye namaxesha amandulo, abanye abantu babophe i-mugwort kunye neengcongolo kwi-bunch, baze bayifake kwioli ethile baze bayikhanyise ukuze bakhanyise. Ethubeni, umntu othile wasongela ingcongolo ngelaphu waza wayizalisa ngekhambi ukuze ayivuthe.
Izinto eziphambili zamakhandlela yiparafini (C₂₅H₅₂), eyenziwe kwiqhekeza le-wax yeoli emva kokushicilela okubandayo okanye i-solvent dewaxing. Ingumxube wealkanes eziliqela eziphambili, ingakumbi n-dodecane (C22H46) kunye n-dioctadecane (C28H58), equlathe malunga 85% carbon kunye 14% hydrogen. Izinto ezincedisayo ezongeziweyo ziquka ioli emhlophe, i-stearic acid, i-polyethylene, i-essence, njl., apho i-stearic acid (C17H35COOH) isetyenziselwa kakhulu ukuphucula ukuthambile, kwaye ukongezwa okuthe ngqo kuxhomekeke kuluphi uhlobo lwekhandlela eziveliswayo. Kulula ukunyibilika, ukuxinana ngaphantsi kwamanzi kunzima ukunyibilika emanzini. Ubushushu bunyibilika bube bulwelo, obungenambala bucace kwaye bunobushushu obuncinci, bunokunuka iparafini ngevumba elikhethekileyo. Xa ibanda, iba mhlophe qhwa, ibe nevumba elikhethekileyo.
Ukuvutha kwekhandlela esikubonayo ayikokutsha kweparafini eqinileyo, kodwa isixhobo sokutshisa sitshisa umbindi womqhaphu, kwaye ubushushu obukhutshwayo benza ukuba iparafini inyibilike kwaye iphinde ibe ngumphunga ukuze ivelise umphunga weparafini, otshayo. Xa ikhandlela lilayita, ilangatye lokuqala lincinci kwaye ngokuthe ngcembe likhudlwana. Idangatye lihlulwe libe ngamaleko amathathu (idangatye langaphandle, ilangatye elingaphakathi, intliziyo yedangatye). Undoqo wedangatye ikakhulu ngumphunga wekhandlela kunye nowona bushushu uphantsi; iparafini yomlilo yangaphakathi ayitshiswa ngokupheleleyo, iqondo lobushushu liphezulu kuneziko lomlilo, kwaye liqulathe amasuntswana ekhabhoni; Idangatye elingaphandle linxibelelana nomoya nomoya, kwaye ilangatye lelona liqaqambile, litshiswe ngokupheleleyo, kunye nobushushu obuphezulu. Ngoko ke, xa intonga yematshisi icaba ngokukhawuleza edangatyeni ize isuswe emva komzuzwana omnye, intonga yematshisi echukumisa inxalenye yedangatye elingaphandle iba mnyama kuqala. Ngomzuzu wokucima ikhandlela, unokubona i-wisp yomsi omhlophe, kunye nomdlalo ovuthayo wokukhanyisa umsi omhlophe, unokuvuselela ikhandlela, ngoko kunobungqina bokuba umsi omhlophe uqinile amasuntswana amancinci aveliswa yiparafini. umphunga. Xa ikhandlela livutha, iimveliso zokutsha ziyi-carbon dioxide kunye namanzi. Inkcazo yeMichiza: C25H52 + O2 (ikhanyisa) CO2 + H2O. Into evuthayo kwibhotile ye-oxygen yilangatye elikhanyayo elimhlophe elikhanyayo, ukukhulula ukushisa, kunye nenkungu yamanzi eludongeni lwebhotile.
