description The invention provides a method for recovering tartaric acid from chiral phenylethylamine tartrate, which comprises the following steps: dissolving chiral phenylethylamine tartrate in water or recovered water, and adding alkali for dissociation; after the dissociation is finished, heating and standing for layering; after standing and layering, removing an oil layer, cooling a water phase, filtering to obtain water which is recycled water, drying solid tartrate obtained after filtering, dissolving the solid tartrate in a solvent, adding acid, reacting, and after the reaction is finished, filtering and drying the solvent by distillation to obtain tartaric acid. According to the present invention, by using the solubility difference of the tartrate at different temperatures, the highest recovery rate of the tartaric acid can achieve 99% through the cooling precipitation and the water phase circulation application, and the method has characteristics of simple operation, high efficiency, excellent industrial applic
