A new heterogeneity racemization technology of valine in an ethanol solution of dibenzoyl-L-tartaric acid was described.Racemization kinetics of this process was studied.Racemization ratio of valine could be gradually increased when the amount of dibenzoyl-L-tartaric acid and the time of racemization were increased.For L-Valine,the relationship between the rate constant of racemization and its reaction temperature was roposed,i.e.:k=0.015 5e^{-13 200/RT},E_a of the heterogeneity racemization is much less than E_a of the racemization in the basic solution.The heterogeneity racemization technology would be suitable for large-scale industrial manufacture.
