Este uşor solubilă chiar la rece în aldehida etilică şi în acid acetic glacial, precum şi în alcool mai ales la cald, greu solubilă în eter şi în apă. Toţi acizii minerali, precum şi acidul acetic diluat, o hidrolizează imediat chiar la rece, dând substanţele din cari s'a obţinut. Acidul acetic concentrat nu o hidrolizează, dar e suficient să se adauge apă pentru ca hidroliza să se producă imediat. In hidraţii alcalini şi în amoniac se dizolvă puţin la rece, iar la cald se hidrolizează. * * DERIVATUL CU ALDEHIDA BENZOICÂ Henziliden-N-aminoiinflalimida
