Isolation of Caffeine 1. Suppose that in the laboratory preparation of malononitrile, CH.C(CN), the reaction mixture, when diluted with water, afforded 300 mL of an aqueous solution of 30 g of the reaction product malononi- trile, CH2(CN), which is to be isolated by extraction with ether. The solubility of malononitrile in ether at room temperature is 20.0 g per 100...
