| 摘 要： | 以固体酸为催化剂进行醇酸树脂合成反应的研究,采用均匀实验设计方法,考察了载体种类、酸种类、酸浓度、反应温度对合成醇酸树脂的固体酸催化剂催化性能的影响,并由逐步回归法对结果进行回归运算,得到了醇酸树脂酸价的回归模型为:y=1 052.523-8.798x1-23.723x2-4.209x4,计算结果表明,合成醇酸树脂固体酸催化剂的制备最优工艺条件为:载体SiO2、酸H2SO4、酸浓度1.00 mol/L、催化剂使用温度200℃,在上述条件下合成醇酸树脂的固体酸催化荆的活性最高.

| Abstract: | The study on synthesis of alkyd resin using solid acid as catalyst was carried out. The effects of carrier type,acid kind and its concentration,reaction temperature on catalytic activity of solid acid catalyst were investigated by uniform design method.The experimental results was calculated by stepwise regression method,and model of the acid value of alkyd resin was obtained,that is,y=1052.523-8.798x_1-23.723x_2-4.209x_4.The calculated results showed that,and the optimal conditions for preparation of solid... |
