Isingeniso

Ukungena Okuyinhloko: Ester

 

I-isobutyl acetate (isobutyl acetate), eyaziwa nangokuthi “isobutyl acetate”, iwumkhiqizo we-esterification we-acetic acid kanye no-2-butanol, uketshezi olungenambala olubonisa ngale ekamelweni lokushisa, luxubene ne-ethanol ne-ether, oluncibilika kancane emanzini, oluvutha umlilo, nezithelo ezivuthiwe. iphunga, elisetshenziswa ikakhulukazi njenge-solvent ye-nitrocellulose kanye ne-lacquer, kanye nama-reagents amakhemikhali kanye ne-flavour.

 

I-isobutyl acetate inezici ezijwayelekile zama-esters, kufaka phakathi i-hydrolysis, i-alcoalysis, i-aminolysis; Ukwengezwa nge-Grignard reagent (i-Grignard reagent) ne-alkyl lithium, encishiswe nge-catalytic hydrogenation ne-lithium aluminium hydride (i-lithium aluminium hydride); Ukuphendula kwe-claisen condensation ngokwakho noma namanye ama-esters (I-Claisen condensation). I-Isobutyl acetate ingatholwa ngekhwalithi nge-hydroxylamine hydrochloride (NH2OH · HCl) kanye ne-ferric chloride (FeCl), amanye ama-esters, i-acyl halides, i-anhydride izothinta ukuhlolwa.
