Kev Npaj ntawm Iodoform txheej txheem: • Dissolve 5 g ntawm iodine hauv 5 ml acetone hauv lub khob conical. tso tawm. Cia cov ntsiab lus ntawm lub khob rau sawv ntsug li 10 - 15 feeb. Lim cov av daj ntawm iodoform los ntawm Buchner funnel • Ntxuav lub precipitate nrog dej txias.

Yuav ua li cas rau iodoform synthesis?

Iodoform yog synthesized los ntawm kev kho ib yam ntawm cov no plaub lub tebchaw nrog iodine (I2) thiab sodium hydroxide (NaOH) hauv cov tshuaj tiv thaiv haloform. … Lub xub ntiag ntawm methyl ketone moiety txhais tau hais tias muaj cov carbonyl compounds uas muaj cov qauv CH3COR lossis cawv muaj cov qauv CH3CHROH qhov twg R yog ib pawg alkyl lossis aryl.

YYuav ua li cas ua kom iodoform?

Iodoform tuaj yeem ua ke hauv cov tshuaj tiv thaiv haloform los ntawm cov tshuaj tiv thaiv ntawm iodine thiab sodium hydroxide nrog ib qho ntawm plaub hom organic tebchaw:

1. a methyl ketone: CH_{3COR, qhov twg R yog cov saw hlau organic.}
2. acetaldehyde: CH_3CHO.
3. ethanol: CH₃CH_2OH.
4. secondary alcohols: CH_{3CHROH, qhov twg R yog ib pawg alkyl lossis aryl.}

Koj tuaj yeem npaj iodoform los ntawm ethanol li cas?

Kev npaj ntawm Iodoform

1. (a) Nrog ethanol. 2NaOH + I₂ → NaOI + NaI + H_{2O. …}
2. (b) Nrog Propane. CH₃COCH + 3NaOI → CH₃COCI_{3 +3 NOV. …}
3. Kev npaj ntawm iodoform. (i) Dissolve 5 g ntawm iodine nyob rau hauv 5 ml propane los yog ethanol nyob rau hauv 100 ml conical flask los yog round bottomed (R. B.) …
4. YCrystalization ntawm iodoform.

hom tshuaj tiv thaiv yog iodoform?

Iodoform cov tshuaj tiv thaiv: Cov tshuaj tiv thaiv tshuaj uas muaj methyl ketone oxidized rau carboxylate los ntawm cov tshuaj tiv thaiv nrog aqueous HO^- thiab I ₂. Cov tshuaj tiv thaiv kuj tsim iodoform (CHI _{3), cov khoom daj uas tuaj yeem ua los ntawm cov tshuaj tiv thaiv sib tov.}
