Drying of Organic Substances- purification of organic compounds
Several solids are dried first by pressing them gently in between folds of filter papers. Compounds that neither decompose on heating nor melt below 100oC are dried through keeping them in steam or oven maintained at 110oC. Substances that decompose on heating are dried by keeping them in a vacuum desiccator consisting of an appropriate dehydrating agent such as fused CaCl2, conc. H2SO4, P4O10 solid KOH or NaOH, etc (desiccant).
