摘　　要：采用氯乙酰氯和氯丁酰氯两种ω-氯代酰氯化试剂,在Lewis酸催化剂存在下,于室温下分别对聚砜(PSF)材料实施了Friedel-Crafts酰基化反应,制备了氯代酰基化(CA)聚砜材料CAPSF。用FT-IR、1H-NMR与佛尔哈德分析法表征了该产物的化学结构与组成。结果表明:在室温(25°C)下,以CH2Cl2为溶剂,以SnCl4为Lewis酸催化剂,聚砜的氯代酰基化反应可以顺利地进行,反应3 h,即可制得氯含量为0.5 mmol/g的产物;采用氯丁酰氯对PSF进行氯代酰基化反应的效果明显好于氯乙酰氯。Friedel-Crafts acylation reactions of polysulfone（PSF） membrane material were conducted in the presence of Lewis acid catalysts at room temperature using two kinds of ω-chloroacyl chloride,chloroacetyl chloride and chlorobutyryl chloride,and chloroacylated polysulfone（CAPSF） were prepared.The chemical structure and composition of the product were characterized by FT-IR,1H-NMR and Volhard methods.The reaction processes on the chloroacylation reactions of PSF were primarily investigated.The experimental results show that the chloroacylation reaction of PSF can be carried out successfully,and a product CAPSF with a chlorine content of 0.5 mmol/g can be obtained in 3 h at room temperature（25°C） with CH2Cl2 as solvent and SnCl4 as Lewis acid catalyst.The experimental results also indicate that chlorobutyryl chloride is better than chloroacetyl chloride in the chloroacylation reactions.
