Latest Patents

Arifuku holds a patent for a method of refining benzoic acid. This invention relates to a process for purifying benzoic acid continuously to a purity of 99.9% or more. The process involves introducing crystals of crude benzoic acid into a continuous crystallization apparatus. The apparatus is equipped with a stirrer and a heating device, allowing for counter-current contact of the falling crystals with the melt generated by heating. The purified benzoic acid is withdrawn as melt from the lower portion of the apparatus, while the mother liquor is removed from the upper portion. This method enables the preparation of high-purity benzoic acid continuously in a relatively simple apparatus at high efficiency. Arifuku has 1 patent to his name.
