Abstract The preparation and IR properties of 1-butylamine, dimethylamine, trimethylamine, triethylamine, benzylamine, 4-methylaniline and 4-aminobenzenesulfonic acid modified glutaraldehyde crosslinked chitosan activated with cyanuric chloride were studied. The absorption of ν(O—H) and ν(N—H) at 3 430-3 440 cm-1, ν(C—O—C) at 1 155 cm-1, ν(C—OH) at 1 030 cm-1 and ν(C—O) of β-D-glucose at 899 cm-1 were not shifted obviously. The absorption of δ(C—H) at 1 400-1 384 cm-1 and ν(C—OH) at 1 095 cm-1 varied markedly. The ν(CN) absorption of crosslinked chitosan was at 1 640-1 650 cm-1. The skeleton vibration absorption of 1,3,5-triazine ring was at 803-812 cm-1 and 1 584-1 590 cm-1. With different deacetylation or substitution, the amide Ⅰ, Ⅱ, Ⅲ absorption at 1 650, 1 600 and 1 310 cm-1 varied obviously. When modified with 1-butylamine, dimethylamine, benzylamine, 4-methylaniline and 4-aminobenzenesulfonic acid, strong absorption of δ(NH+3) appeared at 1 517-1 530 cm-1, which was weakened or disappeared when modified with trimethylamine or triethylamine, but a series of new absorption of ν(C—N) appeared at 1 400-1 500 cm-1.
