Description
Summary:Over the years the demand for Pyruvic acid (PA) is increasing due its huge consumption in food, pharmaceutical, and agrochemical industries. The biotechnological method for PA manufacturing is an efficient, environment-friendly, and cost-effective method over chemical synthesis. Along with the production process, down streaming processes such as separation and purification of acid plays a vital role. Several techniques such as precipitation, adsorption, distillation, membrane-based separation and solvent extraction are developed to recover pyruvic acids. However reactive extraction (RE) is a more attractive novel technique wherein the reaction accomplished between extractant and acid in an aqueous phase. It gives many dividends such as the improved acid recovery with better product purity, extraction of acid, and recovery of solvent. However, in the RE process, the primary challenge is to examine selective and efficient solvents for acid recovery by extraction in industrial operations. Based on solubility parameters such as Hansen Solubility Parameter (HSP), an attempt is made in the presented work, to foresee a suitable solvent and diluents set for separation of PA using RE. This HSP is used to calculate distribution coefficient of acid mathematically. In this paper, the efficient extractants and diluents pair used for PA recovery by RE based on the mathematical model are discussed. In the mathematical model, binodal curve shows aliphatic amines gives better results than phosphorus based extractant and the performance of diluents get varied according to the type of extractant used. The studies are extremely valuable in the development of reactive extraction process of pyruvic acid.
