Abstract
A method for crystallizing succinic acid includes agitating a succinic acid reaction solution with a jet-flow agitator that is rotated at low speed and has a low volume power density; compared with the conventional agitators, the jet-flow agitator helps increase the uniformity of succinic acid particles, shorten the time required for crystallizing succinic acid, and raise the yield of the crystallized succinic acid as well as purity of crystallized succinic acid having a purity of 99.8-99.9%.
