Synthesis of polyols from epoxidised soybean oil over HZSM-5 catalyst
|
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....
