Orthoacetic acid is believed to be impossible to isolate, since it would readily decompose into acetic acid and water. It may have a fleeting existence in aqueous solutions of acetic acid.[2]
Orthoacetate anions
editThe three hydroxyls of CH3C(OH)3 could be deprotonated, leading successively to CH3C(OH)2(O–) (dihydrogenorthoacetate), CH3C(OH)(O–)2 (hydrogenorthoacetate), and finally CH3C(O–)3 (orthoacetate).
Orthoacetate esters
editThere are many stable organic compounds with the trivalent moiety H3CC(OR)3, which are formally esters of orthoacetic acid and called orthoacetates. They include trimethyl orthoacetate and triethyl orthoacetate, which are commercially available.
