摘要：

A method is described for producing highly purified solvents for use in pesticide residue analysis by GLC, particularly when an electron-capture detector is employed. Themethod consists of a sulfuric acid wash, astrongly alkaline permanganate reflux, anddistillation. The solvents prepared by this method (when concentrated 100 to 1) gavenarrow solvent peaks and no later eluting peaks upon gas chromatographic analysis. In both respects, the solvents prepared by this method were superior to commercially available pesticide grade solvents. © 1969, American Chemical Society. All rights reserved.
