[Improvement of the process of producing pseudoephedrine hydrochloride]
Objective:
To improve the design of the technological process so as to solve the long existing quality problem in the process of producing pseudoephedrine hydrochloride.
Method:
Pseudoephedrine hydrochloride was developed on basis of developing pseudoephedrine. And its preparation condition was observed.
Result:
Pseudoephedrine hydrochloride obtained in the improved process didn't show tendency to agglomerate, which solves the quality problem of the product and the rate of production was raised.
Conclusion:
The improved process of producing pseudoephedrine hydrochloride has great application value.
