1.Ethyl acetate ti wa ni rọọrun hydrolysed, ati ki o tun maa hydrolysed lati dagba acetic acid ati ethanol ni niwaju omi ni yara otutu. Awọn afikun awọn iye itọpa ti acid tabi ipilẹ le ṣe igbelaruge iṣesi hydrolysis. Ethyl acetate tun le faragba alcoholysis, ammonolysis, ester paṣipaarọ, idinku ati awọn miiran wọpọ aati ti gbogbo esters. O ṣajọpọ funrararẹ ni iwaju irin iṣuu soda lati ṣe 3-hydroxy-2-butanone tabi ethyl acetoacetate; o fesi pẹlu Grignard reagenti lati dagba ketone, ati siwaju sii lenu yoo fun onimẹta oti.
