Study on Optimization of Product Processing of Pyruvic Acid Its Separation and Purification
Abstract
The preparation of pyruvic acid from lactic acid with hydrogen peroxide as the oxidant and ferrous sulfate as the catalyst was carried out with the ratio of lactic acid and hydrogen peroxide being 1:1.1 the reaction was processed at 40 ℃ and the amount of ferrous sulfate was 1.5g. After 4 hours, raw product of pyruvic acid was taken and the separation and purification process started using an ion exchanging resin D315 then vacuum distillation respectively and pyruvic acid content was determined by the UV spectrophotometer.
Keywords: lactic acid; pyruvic acid; catalytic oxidation; UV spectrophotometer
