    摘要： A process for the preparation of 1,3-propanediol bis(p-aminobenzoate) is described, comprising reacting a p-aminobenzoic acid alkali metal salt with dihalogenated propane in an aprotic polar solvent. In accordance with this process, diesterification proceeds under mild conditions without causing any undesirable side reactions and, therefore the desired 1,3-propanediol bis(p-aminobenzoate) can be obtained in high purity and high yield.
