Reduction of o-Hydromandelic Acid for Preparation of o-Hydrophenylacetic Acid

摘要

In this work, reduction of o-hydromandelic acid to o-hydrophenylacetic acid was investigated. Inorganic and metal catalysts were used in the process of reduction to look for a suitable way for transferring o-hydromandelic acid to o-hydrophenylacetic acid. Of all the catalysts, Raney-Ni has the favorable catalytic activity and the orthogonal test was investigated to determine the optimal condition. The yield of o-hydrophenylacetic acid can up to 90%.
