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16 h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177.4 mgKOH/g。
Soybean oil polyols was synthesized from epoxidised soybean oil （ESBO） and methanol via a ringopening 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 177.4 mgKOH/g, respectively, at 140 ℃ and a reaction time of 16 h.
