Furthermore, a method for higher ester yield, in which methanol was additionally introduced into the reaction system immediately before the beginning of phase separation due to byproduct glycerin to maintain the reaction system in a homogeneous state, was proposed. This method led to superfast and high-yield transesterification with a yield exceeding 96% at 3 min.
