羧基树脂与磺酸基树脂的制备

摘要课题的主要研究内容是通过原料聚苯乙烯小球制备含有特定基团的羧基树脂和磺酸树脂，再测定羧基树脂与磺酸树脂小球的功能基含量。利用共聚法，通过磺化、磷酸化接枝相关基团，制备所需共聚物。反应过程主要是硝化氧化反应以及磺化氧化反应。反应原料是氯球与浓硝酸或浓硫酸，反应得到含有羧酸基团或磺酸基团的树脂。在测定过程中，利用KBr压片法（KBr压片法广泛用于红外定性分析和结构分析）进行常量组分的定量分析。再根据相应树脂进行红外谱图性能测试以及氯球分子内特定功能基团的测定。实验过程中用滴定管测定反应基团含量，利用红外分析仪进行FI-IR性能分析。35346

Preparation of carboxyl resin and sulfonic resin
Abstract
This artical mainly researched the preparation of carboxyl resin and sulfonic acid resin by polystyrene beads which contained specific groups, and the functional group content of carboxyl resin and sulfonic acid resin ball were determined. The copolymer was prepared by the copolymerization of the sulfonated and phosphorylation to graft related groups. The main reaction process was nitration oxidation and the reaction of sulfonated oxidation. The raw material of the reaction was the chlorine ball with concentrated nitric acid or concentrated sulfuric acid, and the resin containing carboxylic acid groups or sulfonic groups was obtained. In the measurement, the quantitative analysis of the constant components was carried out by using KBr method (KBr tablet method widely used for infrared qualitative analysis and structural analysis). According to the IR spectrum of the corresponding resin and the determination of the specific functional groups in the chlorine sphere. Burets was used to determin the content of reactive groups, and FI-IR was used to analysis the perfurman of the resin during the experiment.
