Video: TSOH siv rau dab tsi?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
TSO pom siv nyob rau hauv cov organic synthesis li "organic-soluble" acid catalyst. Piv txwv ntawm siv muaj xws li: Acetalization ntawm aldehyde. Esterification ntawm carboxylic acids.
Ntawm no, P toluenesulfonic acid siv rau dab tsi?
p -toluene sulfonic kua qaub yog dav siv raws li tus neeg sawv cev catalyst hauv kev sib txuas ntawm cov tshuaj, tshuaj tua kab, polymerization stabilizer thiab organic synthesis (esters, thiab lwm yam), xim intermediates thiab resin curing agent. Thiab nws kuj yog qhov feem ntau siv cov kua qaub catalyst hauv organic synthesis.
Thib ob, TsOH organic chemistry yog dab tsi? Toluenesulfonic acid (p-toluenesulfonic acid; TSO ; p- TSO ): Ib qho tshuaj tsw qab sulfonic acid, feem ntau siv los ua cov kua qaub muaj zog. Feem ntau yog hais txog para-methylbenzenesulfonic acid monohydrate (CH3C6H4YOG3H. H2O; pKa -2), tab sis daim ntawv anhydrous kuj tseem siv tau.
Thib ob, TsOH ua dab tsi hauv cov tshuaj tiv thaiv?
Tshooj 17: Aldehydes thiab Ketones. Nucleophilic Ntxiv rau C = O. Hom reagents: ntau tshaj ROH, catalytic p-toluenesulfonic acid (feem ntau sau ua TSO ) nyob rau hauv refluxing benzene. Aldehydes thiab ketones teb nrog ob moles ntawm cawv kom muab 1, 1-geminal diethers feem ntau hu ua acetals.
TsOH is a strong acid?
Raws li nrog rau lwm cov sulfonic kua qaub , TSO yog a muaj zog organic kua qaub . Nws yog hais txog ib lab zaug muaj zog dua tshaj benzoic kua qaub . Nws yog ib qho ntawm ob peb muaj zog acids uas yog khoom thiab, li no, conveniently hnyav.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
