Latest Patents

Kukidome's latest patents focus on a novel process for the production of high-quality bisphenol A. This process involves producing bisphenol A from a neutral crystalline adduct of bisphenol A and phenol. The adduct is fused in an atmosphere with a maximum oxygen content of 0.005% by volume, followed by the evaporation of liberated phenol. To enhance the quality of the product, the crystalline adduct may be mixed with an aliphatic carboxylic acid before fusion to reduce coloring. When using an acidic crystalline adduct, a strong alkali salt of an aliphatic carboxylic acid is recommended. Additionally, the interior surfaces of the apparatuses used for fusion and evaporation should be washed with an organic solvent to eliminate oxygen. The evaporation of phenol is effectively performed through a two-stage steam stripping process, where a used stripping gas from the second stage is utilized in the first stage, while steam is employed in the second stage.
