| 主权项 | 1. PROCESS FOR MODIFYING VEGETABLE OIL, characterized by the fact that it comprises the following steps: a) react at least one monohydric alcohol, with a chain size of more than 3 carbon atoms, and/or at least one polyhydric alcohol of any type with an alkaline metal to generate an alcoxide; and b) perform the transesterification of at least one epoxidized vegetable oil with said alcohol (or alcohols), using the alcoxide generated in step a) as catalyst. | ||
