Abstract
The tryglyceride of vegetable oils should have at least one of unsaturated fatty acid moiety to be modified with sulfur acid catalyst in peracetic acid co-reagent, to be introduced to the desired hydroxyl functional groups in soy-polyol structure. A series of screening reactions have indicated the ratio of acetic/peroxide acid 1:7.25 (mol/mol) with temperature 600C is the best condition for soy-epoxide to be up-scaled to 10 and 20 folds from initials. A 90 minutes is the best lenght of reaction for polyol to be synthesized where the oxirane value and acid value occured are quite preferable for the proceed reactions. The recommended reactor volume is multiple of 400 mL. There are tendency of increasing the acid number if the volume enlarged 10 times, so it needs repeated netralizations. New methods are need for the cost efficient.
