Daim ntawv thov: Methyl txiv kab ntxwv tau siv rau hauv kev sim thiab kev lag luam thiab kev ua liaj ua teb rau pH tswj cov tshuaj tiv thaiv thiab acid-base titration tsom xam ntawm cov khoom siv tshuaj thiab cov khoom nruab nrab.Hauv kev lag luam luam ntawv thiab dyeing, pH tshuav ntawm cov ntaub yuav tsum tau ntsuas nrog qhov ntsuas thiab ntxuav kom cov ntaub nruab nrab.Yog tias muaj acidity ntawm Chemicalbook txiv hmab txiv ntoo daim ntaub, nws yuav cuam tshuam nws cov xim thiab ceev thaum dyed los yog luam tawm nrog reactive dyes.Qhov tsis zoo ntawm methyl txiv kab ntxwv qhia yog tias cov xim daj-liab yog qhov nyuaj dua los txheeb xyuas, thiab tam sim no tau hloov los ntawm ntau qhov ntsuas.Methyl txiv kab ntxwv kuj yog ib qho azo dye uas siv tau los luam thiab dye textiles
Acid-base titration indicator "Methyl txiv kab ntxwv yog cov feem ntau siv acid-base titration qhia hauv analytical chemistry. Nws cov concentration ntawm 0.1% aqueous tov muaj pH ntawm 3.1 (liab) rau 4.4 (daj). puag, Titration ntawm cov hauv paus tsis muaj zog.Nws muaj nyob rau hauv daim ntawv ntawm sulfonic acid sodium ntsev nyob rau hauv nruab nrab los yog alkaline tov, thiab hloov mus rau hauv sulfonic acid nyob rau hauv acidic tov, thiaj li hais tias cov acidic sulfonic acid pab pawg neeg cov ntaub ntawv nrog lub hauv paus dimethylamino pawg nyob rau hauv lub molecule. Daim ntawv ntsev sab hauv (paraquinone qauv) ntawm p-dimethylaminophenylazobenzenesulfonic acid ua ib qho kev sib txuas uas muaj cov qauv p-quinone, yog li cov xim hloov raws li, thiab nws tsis haum rau titration ntawm cov organic acid tebchaw Nws kuj yog siv rau kev txiav txim spectrophotometric ntawm chlorine. , bromine thiab bromide ions .Nws kuj yog siv rau lom dyeing, thiab lwm yam. Methyl txiv kab ntxwv tau siv nyob rau hauv lub chaw soj nstuam thiab industrial thiab ua liaj ua teb ntau lawm rau pH tswj cov tshuaj tiv thaiv thiab kua qaub rau tshuaj cov khoom thiab intermediates Alkali titration tsom xam.Hauv kev lag luam luam ntawv thiab dyeing, qhov seem pH ntawm cov ntaub yuav tsum tau ntsuas nrog qhov ntsuas thiab ntxuav kom cov ntaub nruab nrab.Yog hais tias cov ntaub muaj acidity, nws yuav cuam tshuam nws cov xim thiab xim thaum dyed los yog luam tawm nrog reactive dyes.Ceev ceev.Qhov tsis zoo ntawm methyl txiv kab ntxwv qhia yog tias cov xim daj-liab yog qhov nyuaj rau txheeb xyuas, thiab tam sim no tau hloov los ntawm ntau qhov ntsuas (saib "phenolphthalein").Methyl txiv kab ntxwv kuj yog azo dye, uas tuaj yeem siv rau kev luam ntawv thiab dyeing textiles.
Siv: Raws li acid-base qhia, pH3.1 (liab)-4.4 (daj), kuj siv rau lom dyeing.
Kev siv: acid-base qhia, pH discoloration ntau ntawm 3.1 (liab) mus rau 4.4 (daj), kev txiav txim siab ntawm alkalinity ntawm cov ntxhia hauv acids, muaj zog hauv paus thiab dej;volumetric kev txiav txim siab ntawm tin (Sn2+ fades methyl txiv kab ntxwv thaum rhuab);Kev txo qis Decolorizing qhov taw qhia rau oxidants (Ti3+, Cr2+) thiab muaj zog oxidants (chlorine, bromine);spectrophotometric kev txiav txim siab ntawm chlorine, bromine thiab bromide ions;nws tuaj yeem ua ke nrog sodium indigo disulfonate los yog bromocresol ntsuab los ua ib qho kev qhia sib xyaw kom txo qis cov xim Domain thiab txhim kho qhov ntse ntawm cov xim hloov;redox ntsuas xws li trivalent arsenic lossis antimony rau potassium bromate titration
Kev Siv: Acid-base indicator, achromatic indicator of strong reduce agent and strong oxidant, cytoplasmic indicator, histological contrast stain, pollen tube staining.Tus nqi pH hloov xim ntau ntawm 3.1 (liab) mus rau 4.4 (daj), thiab txiav txim siab alkalinity ntawm cov ntxhia hauv acids, muaj zog alkalis thiab dej.Volumetric txiav txim siab ntawm tin (Sn2+ discolors methyl txiv kab ntxwv thaum kub).Qhov taw qhia decolorizing rau muaj zog txo cov neeg ua haujlwm (Ti3+), Cr2+) thiab cov tshuaj muaj zog oxidizing (chlorine, bromine).Spectrophotometric kev txiav txim siab ntawm chlorine, bromine thiab bromide ions.Nws tuaj yeem ua ke nrog sodium indigo disulfonate lossis bromocresol ntsuab los ua ib qho kev qhia sib xyaw kom txo cov xim hloov ntau yam thiab txhim kho qhov ntse ntawm cov xim hloov.Redox ntsuas xws li trivalent arsenic lossis antimony rau potassium bromate titration.
