中文摘要:
      以水为溶剂,将三聚氯氰与4-羟基苯磺酸缩合制得对-(4,6-二氯-1,3,5-三嗪-2-氧基)苯磺酸钠(简称为TSP),经过FTIR、1HNMR对其分子结构进行表征,分析结果表明:三聚氯氰与4-羟基苯磺酸发生了反应并形成了目标产物。将TSP用于脱灰软化绵羊皮的鞣制,以鞣后坯革的收缩温度及物理感官作为评价鞣制效果依据,通过单因素实验法得到合理的鞣制条件:液比为1,鞣剂用量25%(以绵羊灰皮质量计),鞣制温度以25℃、40℃、50℃阶梯上升,每个温度鞣制2h,鞣制总时间为6h,通过提碱使浴液pH最终维持在5.5~6.0。皮革鞣制实验结果表明:TSP化合物鞣制的坯革收缩温度可达78℃,坯革色泽浅白,粒面平细,革身具有饱满的手感,该化合物作为一种有机鞣剂具有良好的制革应用前景。
英文摘要:
      P-[(4,6-dichloro-1,3,5-triazin-2-yl)-oxy]benzene sulfonic acid sodium salt(TSP) was synthesized by condensation reaction of cyanuric chloride and p-phenolsulfonic acid in the presence of water.The molecular structure of TSP was characterized by FTIR and 1HNMR,then the analysis results showed that cyanuric chloride reacts with p-phenolsulfonic acid to form the target product.TSP was applied to delimed and bated sheep skin.Through the shrinkage temperature and physical sense of the leather,as a basis for evaluating the tanning effect,the reasonable tanning condition was obtained by single factor experiment:100% water,25% TSP(based on the weight of limed sheepskin),the tanning temperature in three stages of 25℃、40℃ and 50℃,and each temperature stage was tanned for 2 hours,the total tanning time was 6 hours and the ultimate pH was kept at 5.5~6.0 by basification.The results indicated that the shrinkage temperature of crust leather could reach 78℃ or so,and the leather had fine white grain and good touch.As a organic tanning agent,the compound has a good application prospect in leather making.
