ldehyde (aldehyde-1) and 4-(2-bromoethyl)benzaldehyde (aldehyde-2), and underwent dehydrohalogenation, under basic conditions (10°C), to yield respective vinyl derivatives. All newly synthesized compounds were structurally characterized by solubility tests, elemental analysis, infrared spectroscopy (FTIR), thermogravimetry (TGA), proton nuclear magnetic resonance ((1)H NMR), and X-ray diffraction (XRD)
甲壳素(Cn)从甲壳纲Astacus leptodactylus(亚美尼亚塞凡湖)的甲壳中提取,然后转化为脱乙酰基衍生物壳聚糖(Cs)。通过Cs与4-(2-氯乙基)苯甲醛(醛-1)和4-(2-溴乙基)苯甲醛(醛-2)相互作用合成新颖的席夫碱(CsSB),并在碱性条件下进行脱卤化氢(10) ℃),得到各自的乙烯基衍生物。所有新合成的化合物均通过溶解度测试,元素分析,红外光谱(FTIR),热重分析(TGA),质子核磁共振((1)H NMR)和X射线衍射(XRD)进行结构表征。
