扼要介绍因升华凝华技术发展迟缓而影响它的应用,利用开发研究干燥机积累经验并结合升华凝华的需要而开发连续升华凝华机,供节能升华精制高纯度苯甲酸的探讨和研究。
This paper briefly introduces the application of sublimation desublimation technology to retard the development of sublimation technology. Based on the experience of development and research of dryer, combined with the need of sublimation and desublimation, a series of sublimation and desublimation desalination machines are developed for energy - saving and sublimation refined high - purity benzoic acid.
