Abstract: The invention relates to a process for the production of 1,4-butanediol comprising the preparation of a fermentation broth comprising 1,4-butanediol from renewable sources and water, separation of a liquid fraction comprising said 1,4-butanediol and water from one or more solid fractions, said liquid fraction comprising 2-pyrrolidone in an amount higher than 80 ppm, one or more passages of the resulting liquid fraction through a bed comprising one or more cation-exchange resins thereby providing an output pH of said liquid fraction from 4 to 2, one or more passages of the resulting liquid fraction through a bed comprising one or more anion-exchange resins thereby providing an output pH of said liquid fraction from 8 to 11, and the distillation of the liquid fraction thereby provided so as to obtain a composition having a concentration of said 1,4-butanediol higher than 99.0% by weight and comprising 2-pyrrolidone in an amount lower than 6 ppm. The resulting composition should exhibit an APHA color value after ageing of less than 30.
