In general, the reaction rate of fat and oil saponification is slow, while using dipropylene glycol as a solvent accelerated the reaction up to 500 times faster than without the use of dipropylene glycol. In this work, we describe the soap preparation from rapeseed oil using this rapid saponification method, and also report the results of a practical class at a senior high school.
