Abstract

A continuous vaporization system for the purification of organic hole-transport materials is proposed to enhance the production rate. A detailed configuration to change a conventional batch process into a continuous one was suggested. The operating strategies of the continuous process were determined from experimental results. Fundamental experiments concerning liquid flow rate through a vertical pipe and product shape were performed. The liquid flow was successfully predicted by using the Hagen-Poiseuille equation with a correction factor, and a suitable tube design could be estimated to obtain a droplet product. Moreover, an operating temperature window was suggested for uniform shape and size of the final product. This study will be useful for improved process efficiency and successful operation of this process.
