摘　　要：采用DDHI物系对新型高效降膜结晶技术的分离提纯机制进行了实验研究;采用减压精馏和熔融结晶相耦合的方法提纯了该物质,并考察了管外降膜结晶过程中结晶和油浴时间等对分离效果的影响。This experimental study on the following film crystallization process is carried out by using a binary system of DDHI. The influence of various process parameters inchding crystallization time, initial inlet temperature of coding oil and melt concentration on falling film crystallization is discussed for falling film taking place on the external surface of a central tube.
