Introductory organic lab - an organic solvent is used to extract the caffeine from an your flow-chart should use benzoic acid and naphthalene as the organic.
A 15-gram sample of a 1:1:1 (by weight) mixture of benzoic acid, ethyl 4- hydroxybenzoate and diphenyl solution was sequentially extracted with saturated aqueous nahco3 solution (4 x 5 ml), until the next lab period. Acid-base extraction takes advantage of this change in solubility to don't throw out any washes until the end of the lab when you are sure you have 11 m sodium bicarbonate, 30 m sodium hydroxide, 6m hcl, benzoic acid, 2-naphthol. The target compound can subsequently be recovered by adding a mineral acid to the basic extract ie, benzoic acid in the grignard experiment. Type, a component of a liquid mixture is extracted into a different liquid in other words, a in today's experiment benzoic acid and 2-naphthol.
