Bromothymol xiav kua yog ib qho qhia.
Qhov qis qis ntawm CO2 ua rau nws tig los ntawm xiav mus rau ntsuab, thiab qhov siab dua ntawm CO2 ua rau nws tig los ntawm xiav mus rau ntsuab thiab tom qab ntawd daj. Ib pab pawg sim siv cov cuab yeej sim uas tau pom hauv daim duab los ua cov haujlwm hauv qab no ntawm 25 ° C rau ntau zaus:
Qhib li qub a thiab B, thawb lub piston ntawm syringe 1, thiab tom qab ntawd kaw a thiab B
Tom qab ib lub sij hawm, lub piston ntawm lub syringe 2 yog rub los txhawb cov roj ntws hauv ob lub raj mis. Kev hloov pauv ntawm cov tshuaj bromothymol xiav tau pom. (thaum li qub a thiab B raug kaw, tag nrho cov cuab yeej raug kaw)
Bromothymol xiav hmoov(ntxiv 1g bromothymol xiav rau 1L ntawm 20% cawv kua) yog ib qho kua qaub-piv qhov taw qhia nrog ib tug discoloration ntau ntawm pH6.0 (daj) mus rau 7.6 (xiav). Cov dej nruab nrab yog nruab nrab, pH yog li 7, thiab nws yuav luag xiav. Tom qab so cov pa roj carbon dioxide, carbonic acid yuav tsim, uas yog cov kua qaub tsis muaj zog, yog li pH yuav tsis poob ntau dhau thiab tig daj. Cov xim hloov pauv yog ntsuab. CO2 tiam tuaj yeem kuaj pom: cov tshuaj bromothymol xiav aqueous hloov ntawm xiav mus rau ntsuab thiab tom qab ntawd daj. Piv nrog rau txoj kev tshawb pom ntawm cov kua qaub ntshiab, nws muaj qhov tseeb dua thiab tsis muaj kev cuam tshuam ntawm SO2.
Raws li kev hloov xim, nws tuaj yeem siv los ntes CO2 tso tawm los ntawm aerobic thiab anaerobic ua pa.
Synthesis txoj kev ntawm bromothymol xiav:
Nyob rau hauv stirring, bromine yog nkag mus rau hauv kev ncua ntawm thymol xiav nyob rau hauv glacial acetic acid, thiab cov tshuaj tiv thaiv yog nqa tawm ntawm 50 degree. Kev npaj ntawm thymol xiav: thymol yog condensed nrog o-sulfobenzoic anhydride los ua thymol xiav.
Ntxiv cov bromine glacial acetic acid heev maj mam mus rau aqueous acetic acid tov ntawm thymol xiav nyob rau hauv stirring, react ntawm 40 ~ 50℃rau 4h, txias kom qis dua 20 degree, lim thiab qhuav kom tau cov xim tsis muaj bromine thymol xiav.
Tom qab cov noob nqus dej, qhov ua pa ntawm cov noob muaj sia nce sai. Cov CO2 tso tawm yaj hauv dej thiab dhau los ua H2CO3, uas txuas ntxiv mus rau H + thiab HCO3 -, yog li ua rau acidity nyob ib ncig ntawm cov noob embryo. Thiab qhov kev hloov ntawm acidity tuaj yeem hloov xim pH qhia BTB. Qhov sib txawv ntawm BTB yog pH 6.0 ~ 7.6, thiab acidity yog daj thiab alkalinity yog xiav. Yog li ntawd, cov pa roj carbon dioxide tso tawm los ntawm kev ua pa tuaj yeem kuaj tau los txiav txim cov noob tuag lossis muaj sia nyob.
Bromothymol xiav yog cov kua qaub-piv qhov taw qhia nrog cov xim ntawm pH 6.0 (daj) txog 7.6 (xiav).
Cov dej nruab nrab yog nruab nrab, pH yog hais txog 7, thiab nws yuav luag lub teeb ntsuab.
Tom qab so cov pa roj carbon dioxide, carbonic acid yuav tsim, uas yog cov kua qaub tsis muaj zog, yog li pH yuav tsis poob ntau dhau thiab tig daj.
Cov xim hloov pauv yog ntsuab lossis cov cim ntawm CO2 raug kuaj pom: cov dej ntshiab txiv qaub yog turbid, thiab cov tshuaj bromothymol xiav aqueous hloov ntawm xiav mus rau ntsuab thiab tom qab ntawd daj.
