Benzene (CAS 71-43-2)yog cov kua uas tsis muaj xim, flammable nrog ib tug qab zib, aromatic tsw. Raws li txoj cai, nws muaj lub nplhaib ntawm 6 carbon atoms, txhua qhov sib txuas rau hydrogen atom, tsim kom muaj kev ruaj khov, cyclic compound. Txawm hais tias nws qhov me me, benzene muaj zog intermolecular rog, ua kom nws nyob rau hauv cov kua hauv lub cev. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias benzene yog cov kab mob carcinogen uas paub, thiab raug rau nws tuaj yeem ua rau muaj kev phom sij loj.
Txiv Hmab Txiv Ntoo thiab Dej Haus
Qee zaum Benzene tuaj yeem pom hauv cov kua txiv hmab txiv ntoo thiab cov dej qab zib. Qhov no tshwm sim vim cov tshuaj tiv thaiv ntawm ntuj antioxidants xws li ascorbic acid (vitamin C) thiab benzoates (preservatives). Thaum ob yam khoom no raug tshav kub, lub teeb, lossis hlau ions, lawv tuaj yeem hnov qab thiab tsim benzene. Txhawm rau txo qhov kev pheej hmoo no, cov tuam txhab tam sim no saib xyuas thiab tswj cov qib ntawm cov khoom xyaw no.
Cov khoom ci
Qee cov khoom ci kuj tseem muaj cov lej ntawm benzene. Thaum lub sij hawm ci, qee cov khoom xyaw thiab flavorings yuav tawg thiab tsim benzene. Piv txwv li, qee cov khoom qab zib lossis cov khoom xyaw hauv lub khob noom cookie tuaj yeem ua rau muaj qhov kub siab - qhov kub thiab txias los tsim cov khoom me me ntawm qhov teeb meem no.
Khoom noj txom ncauj
Hauv cov khoom noj txom ncauj, benzene tuaj yeem tshwm sim los ntawm cov txheej txheem tsim khoom lossis los ntawm cov kab mob hauv cov khoom xyaw. Piv txwv li, yog tias cov roj ua noj uas siv rau hauv cov khoom noj txom ncauj kib tau raug kub hnyiab ntev ntev, nws tuaj yeem ua rau tsim cov benzene. Tsis tas li ntawd, yog tias cov khoom siv raw siv hauv cov khoom noj txom ncauj tsis muaj paug, nws tuaj yeem ua kom pom cov benzene rau hauv cov khoom kawg.
