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 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).

摘要

研究了用三聚氯氰活化的1-丁胺、二甲胺、三甲胺、三乙胺、苄胺、4-甲基苯胺和4-氨基苯磺酸改性的戊二醛交联壳聚糖的制备及其红外性能。在3430 - 3440 cm⁻¹处的ν(O - H)和ν(N - H)、1155 cm⁻¹处的ν(C - O - C)、1030 cm⁻¹处的ν(C - OH)以及899 cm⁻¹处β - D - 葡萄糖的ν(C - O)吸收峰没有明显位移。在1400 - 1384 cm⁻¹处的δ(C - H)和1095 cm⁻¹处的ν(C - OH)吸收峰有明显变化。交联壳聚糖的ν(C = N)吸收峰在1640 - 1650 cm⁻¹处。1,3,5 - 三嗪环的骨架振动吸收峰在803 - 812 cm⁻¹和1584 - 1590 cm⁻¹处。随着脱乙酰度或取代度的不同，在1650、1600和1310 cm⁻¹处的酰胺I、II、III吸收峰有明显变化。用1-丁胺、二甲胺、苄胺、4-甲基苯胺和4-氨基苯磺酸改性时，在1517 - 1530 cm⁻¹处出现强的δ(NH₃⁺)吸收峰，用三甲胺或三乙胺改性时该吸收峰减弱或消失，但在1400 - 1500 cm⁻¹处出现一系列新的ν(C - N)吸收峰。
