Latest Patents

One of Konishi's latest patents is a method for producing trimethylhydroquinone. This inexpensive method addresses the issue of waste catalyst disposal. The process involves several steps: first, reacting isophorone in the presence of an acid catalyst and recovering β-isophorone through distillation. Next, β-isophorone is oxidized with amorphous carbon and a base to yield 4-oxoisophorone. Following this, 4-oxoisophorone is reacted with an acid anhydride in a liquid phase or with a carboxylic acid in a vapor phase, using a solid acid catalyst to produce trimethylhydroquinones. Finally, the trimethylhydroquinones are hydrolyzed to obtain trimethylhydroquinone.
