✦ Synopsis

and glass-stoppered weighing bottles were found very convenient for the microscope slides. Plates took 30-50 min for development while slides required only one-tenth as long.

Plates were sprayed with concentrated sulphuric acid and heated at 150~. Tosylates were identified by spraying with I yO diphenylamine in ethanol and viewing in the. ultraviolet12 before overspraying with sulphuric acid.

RF values should be treated only as a guide and when possible standard samples should be run concurrently. Standards must be applied in the same solvent as that in which the reaction is being carried out. Traces of reaction solvent may greatly influence the rate of movement of compounds especially in the low polarity solvent (E-T).
