Following the procedure of Example 2, a mixture of 172 grams (1.0 mole) of cyclohexane dicarboxylic acid, 265.5 grams (2.25 moles) of 1,4-dioxanemethanol, 75 milliliters of xylene and 0.3 gram of dibutyltin oxide catalyst yields a gray waxy product in 91 percent yield. Recrystallization from an ethanol-water mixture gives the colorless bis-1,4-dioxanemethanol cyclohexanedicarboxylate.
