Latest Patents

Ueda's latest patents include a process for recovering benzyl benzoate and a process for preparing bisphenol A. The first patent details a method for recovering high-purity benzyl benzoate by distilling the residue left after the removal of unreacted toluene and benzoic acid from a reaction mixture. This innovative process allows for the separation of a fraction containing 80 wt % or more benzyl benzoate, along with minimal amounts of benzoic acid and fluorenone. The purification of this fraction through crystallization techniques enables the recovery of high-purity benzyl benzoate at a low cost.

The second patent focuses on a process for preparing bisphenol A through the condensation of phenol with acetone. This process utilizes a cation exchange resin as a catalyst, which is obtained by sulfonating copolymers of monovinyl and divinyl monomers. Ueda's method ensures a long life for the catalyst, maintaining high production efficiency of bisphenol A over extended periods. This innovation is particularly advantageous for economical production in the chemical industry.
