Title:
エポキシ化脂肪酸エステル類からバイオポリオールを製造する方法
Document Type and Number:
Japanese Patent JP6903084
Kind Code:
B2
Abstract:
A method of preparing bio-polyols from epoxidized fatty acid esters, wherein the bio-polyols are synthesized via hydroxylation with epoxidized fatty acid esters and ring-opening reagent, using the acidic ionic liquids as catalysts. The bio-polyols are used to synthesize bio-polyurethane and bio-polyurethane foams. The acidic ionic liquids in this process is used in esterification, epoxidation, and ring-opening reaction to synthesize bio-polyols. The ionic liquids catalysts have several advantages such as easy to separate, reusable, and may reduce pollution.
