摘要
以葡萄糖为原料,经过胺化、CS2亲核加成等步骤合成了一种含硫改性葡萄糖,命名为二硫代氨基甲酸改性葡萄糖(简称DTCG)。采用红外光谱(FTIR)、紫外光谱(UV)等表征手段研究改性葡萄糖的结构。在DTCG的FTIR谱中,分别在1637 cm~(-1)、1400 cm~(-1)处出现v(S-C(?)N)和v(S(?)C-N)吸收峰,说明D-葡萄糖上接上了DTC基团。在UV谱中,葡萄糖、胺化葡萄糖在紫外光区并没有明显吸收,而DTCG分别在257 nm、285 nm处出现DTC基团的两个特征吸收峰,257 nm处为N…C…S基团的π-π~*跃迁,282 nm处为S…C…S基团中硫原子上非成键电子向共轭体系的n-π~*跃迁。电化学测试结果表明,在3%NaCl溶液中加入50 mg/LDTCG后,铜电极的缓蚀性能得到很大提高,缓蚀效率可达98%。
A modified dithiocarbamate glucose(DTCG for short),was synthesized with D-glucose as raw material by means of amination,and CS2 nucleophilic addition.The structural characteristics of modified glucose were investigated by FTIR,UV spectroscopies and so on.The FTIR spectrum of DTCG illustrated that two moderate peaks at 1 637 cm~(-1) and 1 400 cm~(-1) were assigned to v(S-G(?)N) and v(S(?)C-N) vibration,demonstrating that dithiocarbamate radical was grafted on glucose.As for UV spectra,D-glucose and aminated glucose hadn't absorbance in the ultraviolet region while DTCG had two characteristic absorbance peaks of DTC group at 257 nm and285 nm,assigned to π-π~* transition of N-C-S radical and nonbonding electron n-π~* transition of S-C-S radical to conjugated system,respectively.The results of electrochemical measurements showed that DTCG had an inhibition efficiency of 98%for a copper electrode in 3%NaCl solution at a concentration of 50 mg/L.
