Novel process for the Separation and / or recovery of Citric Acid with ion exchange resins and chromatographic

摘要

The present Invention relates to a novel process for the Separation and Recovery of Citric Acid with ion exchange resins and chromatographicWhere the raw materials from Industrial Waste or by-products of fermentation broths, fruits, or any solution that contain IT,Because it can be characterized by a continuous or batch process and consists of the following stages. Stage 1. Saturation.The ion Exchange Column containing a Weakly basic anion Resin as Anger or Rage 93 68 or similarUpward flow is fed into the Broth containing the organic acid at a flow rate between 2 and 25 VC / hr to provoke a fluidized bed, Stage II. Circumvention.The Citrate ion adsorbed to the Resin was eluted with a Mineral acid in downward Flow preferably sulfuric acid at a concentration of 0.1 to 1.5 molar and a flow rate of 2 to 14 VC / hr until a sample of the eluates displayed the first Fire Traces of sulfates. Stage III. dechlorination.The Citric Acid Solution obtained in the previous Stage, if it is colored, it downstream to a Column containing a type Resin xad-4,XAD 16 or similar to a flow rate of 2 to 12 VC / HR, resulting in a Citric Acid Solution transparent.
