The examination of a number of food products recently has revealed that propylene glycol and certain esters of the hydroxy benzoic acids have been used as preservatives. The present research was undertaken for the purpose of preparing a series of glycol benzoates, which might be used as food preservatives.Only a few of the glycol benzoates have been described in chemical literature. Wurtz (1) by whom ethylene glycol was discovered, prepared and described ethylene glycol dibenzoate before 1860. Propylene glycol dibenzoate was first prepared in 1871 by Friedel and Silva (2), by treating silver benzoate with propylene bromide dissolved in anhydrous ether. Trimethylene glycol dibenzoate was
