Paper chromatography was made on barbiturate derivatives with the use of solvents of BuOH : CHCl_3 : NH_4OH and iso-PrOH : CHCl_3 : NH_4OH. In Barbital, Phenobarbital and Allobarbital each substance had a good selectivity but the spotshad a marked tendency to diffuse on the paper. In Pentobarbital, Methylhexabital and Thiopental on the other hand the spots did not diffuse but the separation in each substance was not clear. For the chromatographic separation and detection of Barbital, Phenobarbital, Allobarbital, Ethylhexabital and Metylhhexabital iso-PrOH (or BuOH) : CHCl_3 : NH_4OH=3 : 4 : 3 may be suitable as a developing solvent. For the purpose of separation of Ethylhexabital and Methylhyxabital it was found that the almost all solvents stvdied in this experiment could be used. As the reagent for detection the use of Silver nitrate-Ethanol solvtion is recommended.
