| 摘 要： | 以环氧大豆油（ESBO）和甲醇为原料，通过开环加成反应合成大豆油多元醇。采用红外光谱和核磁共振氢谱对产物结构进行了表征，考察了不同类型的催化剂对ESBO转化率和多元醇生成的影响。结果表明，具有Bronsted酸中心的HZSM-5催化剂对该反应具有优良的催化性能。以HZSM-5为催化剂，在反应温度为140℃、反应时间16h条件下，环氧大豆油转化率可达92.4%，产物多元醇的羟基值为177.4mgKOH/g。

| Abstract: | Soybean oil polyols was synthesized from epoxidised soybean oil(ESBO) and methanol via a ring-opening addition process.The effect of various catalysts on ESBO conversion and polyols formation was investigated and the product structure was characterized by IR and 1HNMR.HZSM-5 exhibits excellent catalytic performance in the transformation of ESBO into polyols due to the presence of Bronsted acid sites.With HZSM-5 as catalyst,the conversion of ESBO and hydroxyl value of the product polyols reach 92.4% and 177.... |
