実験手順
Azelaic acid 94 parts, 0.5 mol.) was heated to 120° C. A catalyst, AMC-2 (commercial chromium salt, 0.8 g) was added. Glycidol (81.5 g, 1.1 mol.) was added dropwise with stirring during 1 hour while keeping the temperature within 115° and 125° C. To complete the reaction, heating at 120° C. was continued for another hour. The product was a viscous liquid which crystallized very slowly to a waxy solid. It had residual acid and epoxy contents of 0.03 and 0.07 meq./g, respectively, and a purity of about 95%; 2,3-dihydroxypropyl groups per molecule: 2; molecular weight; 336.
