Abstract
The present invention relates to methods of manufacturing multiple metal propionates in a single reaction using sodium hydroxide as initiator and propionic acid as solvent. The method provides up to 95% conversion with greater than 60% yield. In addition, the method significantly reduces the cost or production by shortening reaction time, eliminating secondary mixing process, and providing simultaneous drying and micronization steps.
