    Acetic Acid Purification with Sunresin’s Ion Exchange Resins

    Sunresin provides a mature ion exchange resin process for acetic acid purification, which can remove bromine or chloride ions in acetic acid to less than 5ppm, or undetectable levels. The fixed bed mode is recommended for the ion exchange process for acetic acid purification, which runs continuously and removes impurities through the front and back resin columns to improve the removal accuracy and ensure the maximum utilization of the resins. For details, refer to the figure below.

    Sunresin's Ion Exchange Technology Empowers the Lactic Acid Processing Industry

    According to the forecast from 2020 to 2025, the global lactic acid market is growing rapidly, with the growth rate at about 12.8%. This means the value of the lactic acid market will double every five years, from $1.1 billion in 2020 to $2.2 billion in 2025. The major driver for the growth of the global lactic acid market is the soaring demand for polylactic acid as a biodegradable packaging material, which accounts for more than 39% of the lactic acid market demand. Lactic acid is often used as a monomer to make polylactic acid.

    Adsorption and Recovery of p-Chlorobenzotrifluoride with Seplite Resins

    Sunresin’s VOCs treatment resin is a styrene-DVB matrix macroporous adsorption resin with a specially designed resin structure. It has a good mesh structure and a high specific surface area, and can be sieved through the size of the pores. Organic molecules are selectively adsorbed by interaction, intermolecular force or hydrogen bond interaction.

    Sunresin’s adsorption resins for removal of perfluorinated pollutants in water and their production and application

    In Sunresin’s method, the hydrophobicity of the resin is further increased, the degree of crosslinking gets increased, and the pore structure gets adjusted. The adsorption resins have a narrow particle size distribution, uniform pore size and high specific surface area. As the size of micropores in the resin is close to the molecular size of perfluorooctanoate in water, which has a strong selectivity of the adsorbates and can therefore further increase the adsorption rate of perfluorinated compounds.
