Synthesis of Hydroquinone Monopropionate

Hydroquinone monopropionate was synthesized by partially alcoholysized and deacylated of hydroquinone bipropionate in methanol-water solution and alkaline condition with appropriate antioxidant. The synthesis was in mild condition ,short reaction time, lower cost and the product was separated easily. The yield of hydroquinone monopropionate was up to 78. 5%and the purity was 99. 49%.
