Taw qhia

Lub ntsiab nkag: Ester

 

isobutyl acetate (isobutyl acetate), tseem hu ua "isobutyl acetate", yog cov khoom esterification ntawm acetic acid thiab 2-butanol, tsis muaj xim pob tshab kua ntawm chav tsev kub, miscible nrog ethanol thiab ether, me ntsis soluble hauv dej, flammable, nrog cov txiv hmab txiv ntoo mature. aroma, feem ntau yog siv los ua ib qho hnyav rau nitrocellulose thiab lacquer, nrog rau cov tshuaj reagents thiab flavoring.

 

isobutyl acetate muaj cov yam ntxwv ntawm esters, suav nrog hydrolysis, alcoholysis, aminolysis; Ntxiv nrog Grignard reagent (Grignard reagent) thiab alkyl lithium, txo los ntawm catalytic hydrogenation thiab lithium aluminium hydride (lithium aluminium hydride); Claisen condensation cov tshuaj tiv thaiv nrog nws tus kheej lossis nrog lwm cov esters (Claisen condensation). Isobutyl acetate tuaj yeem kuaj pom zoo nrog hydroxylamine hydrochloride (NH2OH · HCl) thiab ferric chloride (FeCl), lwm yam esters, acyl halides, anhydride yuav cuam tshuam rau kev soj ntsuam.
