[Separation of dicarboxylic acid by thin-layer chromatography].

Dicarboxylic acids (C2-C6) were detected on thin-layer chromatography of silica gel G after developing with V(benzene):V(acetic acid):V(water) = 50:40:10 for an hour by dipping the plate in a very short time. The chromogenic reagent was 0.1% bromocresol green alcohol solution adjusted to pH 7. The acid appeared as yellow spots on a blue background.
