Latest Patents
Kumpinsky's latest patents focus on the process for the manufacture of 1,4-bis(4-phenoxybenzoyl)benzene. This compound is synthesized through a reaction of diphenyl ether with 1,4-benzenedicarbonyl chloride at temperatures ranging from 220 to 258 degrees Celsius. The process involves the use of specific iron, gallium, and indium compounds as catalysts. The mole ratio of diphenyl ether to 1,4-dicarbonyl chloride is maintained between 5:1 to 25:1, while the catalyst ratio varies from 1000:1 to 10:1.
In another patent, Kumpinsky describes a heterogeneous system for the same synthesis, utilizing a zeolite catalyst with a ring structure containing 12 oxygen atoms. This zeolite can be in either hydrogen form or iron-exchanged form, allowing for efficient separation from the reaction mixture. The mole ratio of diphenyl ether to 1,4-dicarbonyl chloride varies based on the catalyst form, ensuring high purity of the final product, which is crucial for the synthesis of poly
