Solvency Rating of Petroleum Solvents by Reverse Thin-Layer Chromatography
Abstract
The report describes a new procedure for evaluating the solvency characteristics of petroleum hydrocarbons that are used as solvents and thinners in organic coatings. The method makes use of the principles and practices of thin-layer chromatography and includes a novel change in normal TLC operating procedure. A standard dye is 'spotted' on a glass microber sheet and the edge of the sheet is placed in the solvent to be analyzed. After the solvent has migrated to near the top of the sheet, the sheet is removed, dried, and a ratio of the distances traveled by the dye and solvent is established (R(f) value). The R(f) value of different solvents is related to their solvent power.
