title: [Improvement of the process of producing pseudoephedrine hydrochloride].
abstract: 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.
  
  
  METHODS
  Pseudoephedrine hydrochloride was developed on basis of developing pseudoephedrine. And its preparation condition was observed.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  The improved process of producing pseudoephedrine hydrochloride has great application value.
