Technological improvement on the racemization of dextromisole hydrochloride

To study the new method on the racemization process of dextromisole hydrochloride.Under the specific environments,water was used to replace dimethyl sulfoxide(DMSO) as the menstruum.And the lower specific rotatory power of the D-tetramisole shows that this new method is practical.The improvement on the technology of the racemization of dexeromisole hydrochloride is more available with mild reaction condition and lower price and free from the pollution to the environment,which has great practical value.
