中文摘要：
针对左磷右胺盐生产中使用的普通下出料离心机存在的过滤分离效率低、滤饼卸除困难等问题进行了研究。采用加入乙醇的方法，来降低结晶液黏度，改善了结品液过滤分离的特性。选择了装配有撇液装置的抖袋离心机作为结晶液离心分离的设备，并进行了工业化试验。结果表明：与普通下出料离心机相比，抖袋离心机具有良好的密封性，抖包效果好，基本无滤饼残留，过滤时问短，出料量大，生产效率较普通下出料离心机大幅度提高。研究结果为左磷右胺盐生产中离心分离设备的选择提供了一定的依据，为后续工业生产效率的提高及工作环境的改善奠定了基础。
英文摘要：
The separation process of R-（ ＋ ）-a-phenethylammonium. IR. 2S-（ - ）-cis-1,2-epoxypropyl phosphonate was investigated. The ordinary unloading centrifuges in use have many problems, such as the low efficiency in the filtration separation, the high difficulty in the unloading of filter cake. To solve these problems, firstly, ethanol was added to decrease the liquid viscosity, which can improve the performance of the filtration separation, then a shaking bag centrifuge was chosen as a new centrifuge with the liquid skimming system, and the industrial tests were performed. The tests results show that, compared with the ordinary unloading centrifuge, the shaking bag centrifuge obviously exhibits the advantages of good seal, little residual filter cake, short unloading time, big unloading capacity, and higher production efficiency. These of the centrifuge in the production but also lay the foundation the work environment in the subsequent production
