Latest Patents

Klopfer's latest patents include a process for continuously separating phthalic anhydride from the reaction gas mixture formed by the catalytic oxidation of o-xylene and/or naphthalene. This innovative method involves treating the reaction gas mixture in at least two absorption stages with organic absorbents. The first absorption stage utilizes a mixture of phthalic anhydride and benzoic acid, while subsequent stages may include maleic anhydride.

Another significant patent focuses on the recovery of maleic anhydride from gases containing it. This improved process scrubs maleic anhydride-containing gases with a water or maleic acid scrubbing solution, forming a maleic acid-containing solution. The solution is then concentrated and dehydrated to produce maleic anhydride, which is purified through distillation under vacuum conditions.
