[Preparation and FTIR properties of amino compounds modified glutaraldehyde crosslinked chitosan resin activated with cyanuric chloride].
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 nu(O-H) and nu(N-H) at 3430-3440 cm(-1), nu(C-O-C) at 1155 cm(-1), nu(C-OH) at 1030 cm(-1) and nu(C-O) of beta-D-glucose at 899 cm(-1) were not shifted obviously. The absorption of delta(C-H) at 1400-1384 cm(-1) and nu(C-OH) at 1095 cm(-1) varied markedly. The nu(C=N) absorption of crosslinked chitosan was at 1640-1650 cm(-1). The skeleton vibration absorption of 1,3,5-triazine ring was at 803-812 cm(-1) and 1584-1590 cm(-1). With different deacetylation or substitution, the amide I, II, III absorption at 1650, 1600 and 1310 cm(-1) varied obviously. When modified with 1-butylamine, dimethylamine, benzylamine, 4-methylaniline and 4-aminobenzenesulfonic acid, strong absorption of delta(NH3+) appeared at 1517-1530 cm(-1), which was weakened or disappeared when modified with trimethylamine or triethylamine, but a series of new absorption of nu(C-N) appeared at 1400-1500 cm(-1).
