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 100^oC are dried through keeping them in steam or oven maintained at 110^oC. 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).
