Abstract
A method for preparing sodium taurine as a taurine intermediate is provided in the present disclosure. The method comprises the following steps: providing sodium hydroxyethyl sulfonate and an ammonia source; and placing the sodium hydroxyethyl sulfonate and the ammonia source in an aminolysis reactor for an aminolysis reaction to obtain a mixture containing sodium taurine as a taurine intermediate, wherein the molar ratio of ammonia in the ammonia source to the sodium hydroxyethyl sulfonate is greater than or equal to 25:1. A method for preparing taurine is further provided.
