You are a chemist for Chlorganics, Inc., a company specializing in chlorinated organic compounds. A process engineer, Turner Switchback, has accidentally mixed the contents of four vats containing, respectively, p-chlorophenol, 4-chlorocyclohexanol, p-chlorobenzoic acid, and chlorocyclohexane. The president of the company, Hal Ojinn (green with anger), has ordered you to design an expeditious separation of these four compounds.

Success guarantees you a promotion; accommodate him.
