Acetic anhydride dissolves hauv dej rau kwv yees li 2.6% los ntawm qhov hnyav . Aqueous kev daws teeb meem tsis muaj kev ruaj ntseg vim hais tias, zoo li feem ntau cov kua qaub anhydrides, acetic anhydride hydrolyses muab carboxylic acids. Nyob rau hauv cov ntaub ntawv no, acetic acid yog tsim, cov tshuaj tiv thaiv cov khoom no yog tag nrho cov dej miscible: (CH3CO)2O + H. 2O → 2 CH3CO2H
Yuav ua li cas anhydrides teb nrog dej?
Hydrolysis yog cov lus teb yooj yim tshaj plaws. Dej hydrolyzes anhydrides rau hauv lawv cov carboxylic acids sib xws. Nco ntsoov tias thaum qhov no tshwm sim, koj tau txais ob carboxylic acids. … Acetic acid yuav tshwm sim los ntawm cov tshuaj tiv thaiv.
Vim li cas anhydrides insoluble hauv dej?
Solubility hauv dej
Ethanoic anhydride tsis tuaj yeem hais kom yaj hauv dej vim nws cuam tshuam nrog nws muab ethanoic acid.
Puas yog cov kua qaub anhydrides polar lossis nonpolar?
Acetic Anhydride muaj tsis-polar qauvnrog rau cov molecules hloov tau.
Puas kua qaub anhydrides ua rau dej?
Acid Anhydrides teb nrog dej los tsim carboxylic acids.
