Abstract

Epoxy resin was analyzed by thin layer chroma-tography (TLC) and the influence of solvent polarity, its mixing ratio, and particle size distribution in solid support on the separation of the resin was investigated. The stationary phase of TLC plates used in the experiments was prepared with wet sieving and sedimentation. It is found that the particle size distribution and solvent polarity show a significant effect on the separation, and that there is a suitable condition for TLC of Epoxy resin. It is confirmed that each spot on TLC plate corresponds to a constant n values ranging from 0 to 7. It is evident that THF-chloroform solvent system is applicable to the separation of epoxy resin by liquid chromatography (LC) with gradient technique, because the system shows no absorption in UV spectra region.
