Txhua txoj hauv kev rau kev sib txuas ntawm carboxylic acids tuaj yeem muab tso rau hauv ib qho ntawm ob pawg: (1) hydrolysis ntawm acid derivatives thiab (2) oxidation ntawm ntau cov tebchaw.
Koj ua li cas los tsim cov carboxylic acid los ntawm alkene?
Alkenes tuaj yeem hloov mus rau hauv carboxylic acid dhau ntawm oxidative cleavage ntawm ob daim ntawv cog lus nrog nruab nrab lossis acid permanganate, piv txwv. Txawm li cas los xij, alkene yuav tsum muaj tsawg kawg ib qho hydrogen nyob ntawm ob daim ntawv cog lus, txwv tsis pub tsuas yog ketones tsim.
COOH tsim li cas?
Txawm hais tias nyob hauv chav kuaj lossis hauv lub cev, kev oxidation ntawm aldehydes lossis thawj cov ntawv cawvcarboxylic acids.
Yuav ua li cas rau carboxylic acid?
carboxylic acid, ib chav kawm ntawm cov organic tebchaw uas a carbon (C) atom yog sib txuas rau oxygen (O) atom los ntawm ob daim ntawv cog lus thiab rau pawg hydroxyl (―OH) los ntawm ib daim ntawv cog lusIb daim ntawv cog lus thib plaub txuas cov pa roj carbon atom mus rau hydrogen (H) atom los yog rau qee qhov sib xyaw ua ke.
YKoj ua li cas carboxylic acids?
Aromatic carboxylic acid npaj tau dhau ntawm oxidation ntawm alkylbenzenes. Lub zog oxidation ntawm alkyl benzene compound nrog acidic los yog alkaline poov tshuaj permanganate los yog chromic acid tuaj yeem ua rau tsim cov tshuaj tsw qab carboxylic acid.
