Basing on the practical experience and processing principle , the optimization of producing process , in which the butyl alcohol is abstracted from the water phase by the azeotropic distillation of the partly and mutually dissolved , is studied in this paper by utilizing the properties of the azeotropic distillation of the partly and mutually dissolved system of butyl alcohol and water , from the some questions such as rearranging of the equipments , dissolving with sodium hydroxide , treating of the wasted water , separating water and so on 摘要结合实践经验和工艺原理，利用丁醇和水组成的部分互溶系统的共沸特性，对从青霉素类结晶母液中提纯丁醇的生产工艺进行了分析研究，从设备布局、碱洗、废液处理和分水滞后等方面进行了优化处理。
The results show that all of them have little different effect on the crystalline size of ultrafine powder of a - ahc ^ , but they have greatly different effect on the secondary partical size . the azeotropic distillation is the most effective processing , it can prevent the formation of hard agglomerates and improve the sinter - ability of powder . the mechanism of drying stages preventing the formation of hard agglomerates has investigated 研究了三种不同的干燥方法(直接干燥法、酒精置换干燥法和共沸蒸馏干燥法)对粉体性能的影响。实验表明三种干燥方法对- al _ 2o _ 3粉体的一次粒径的差别性影响不显著，而对其二次粒径的差别性影响则很显著。
