Abstract
The present invention relates to a process for preparing tocol acylate or tocopherol acylate having the following steps: a) combining tocol or tocopherol with an acylating agent to form a reaction mixture; b) irradiating the reaction mixture with microwave energy to from tocol acylate or tocopherol acylate; and c) isolating the tocol acylate or tocopherol acylate from the reaction mixture.

A process for preparing tocopherol acylate comprising:
- a) combining tocopherol and an acylating agent to form a reaction mixture;
- b) exposing the reaction mixture to microwave energy at about 600 to about 1200 watts;
- and
- c) recovering the tocopherol acylate from the reaction mixture.
