PURIFICATION PROCESS USING MICROCHANNEL DEVICES

摘要

A method for providing compound of ultra high pure is provided to refine efficiently and economically the compound having impurities having a relative volatility less than 1.2. A method for providing compound of ultra high pure comprises steps of: separating one or more target compounds from one or more impurity compounds from one or more microchannel devices. The target compounds and impurity compounds have a relative volatility less than 1.2. The target compounds have a purity of 99.99%.
