Kev sib xyaw ntawm Propylene nrog Hypochlorous Acid
Los ntawm qhov kev xav ntawm cov txheej txheem tshuaj tiv thaiv, thaum propylene tshuaj tiv thaiv nrog hypochlorous acid, cov chlorine atom hauv hypochlorous acid qhia txog electrophilicity thiab tawm tsam qhov kawg ntawm electron-rich ntawm propylene double bond, tsim cov chloronium ion intermediate. Qhov no sib haum nrog cov txheej txheem ntxiv electrophilic hauv organic chemistry, uas tau piav qhia meej hauv phau ntawv Basic Organic Chemistry Reaction Mechanisms.
Qhov kev faib tawm ntawm cov tshuaj tiv thaiv ntawm propylene thiab hypochlorous acid yog cuam tshuam los ntawm ntau yam, xws li qhov kub ntawm cov tshuaj tiv thaiv. Thaum qhov kub thiab txias raug tswj ntawm kwv yees li 25 ° C, qhov sib piv ntawm cov khoom tseem ceeb tseem ruaj khov, thiab cov txiaj ntsig ntawm chlorohydrin tuaj yeem ncav cuag li 60%, raws li tau sau los ntawm ntau cov ntaub ntawv sim. Kev xaiv ntawm cov tshuaj tiv thaiv no yog qhov tseem ceeb: nyob rau hauv cov xwm txheej tshwj xeeb, cov khoom kinetic tsim tshwj xeeb, thaum qhov sib piv ntawm cov khoom thermodynamic maj mam nce ntxiv thaum lub sijhawm tiv thaiv txuas ntxiv. Kev tshuaj xyuas theoretical ntawm cov kev hloov pauv hauv kev xaiv tshuaj tiv thaiv rau cov tshuaj tiv thaiv zoo li no tau muab rau hauv Chemical Reaction Kinetics thiab Thermodynamics. Cov kuab tshuaj muaj qhov cuam tshuam tseem ceeb rau cov tshuaj tiv thaiv: hauv cov kuab tshuaj polar xws li ethanol, qhov nrawm ntawm cov tshuaj tiv thaiv nrawm dua vim tias cov kuab tshuaj polar yaj cov reactants zoo dua thiab txhawb kev tsim cov ionic intermediates, qhov kev tshawb pom tau lees paub los ntawm ntau qhov kev sim tshuaj lom neeg. Hauv cov tshuaj tiv thaiv ntawm propylene thiab hypochlorous acid, qhov concentration ntawm hypochlorous acid muaj qhov cuam tshuam loj heev rau kev nce qib ntawm cov tshuaj tiv thaiv. Ntawm qhov qis hypochlorous acid concentration, qhov nrawm ntawm cov tshuaj tiv thaiv qeeb; Thaum qhov concentration nce ntxiv, tus nqi yuav nrawm dua, tab sis qhov concentration siab dhau heev yuav ua rau muaj kev cuam tshuam ntxiv. Cov kev sim qhia tau tias qhov kev cuam tshuam ua tau zoo tshaj plaws ntawm qhov concentration hypochlorous acid ntawm 0.5 mol / L.
