Latest Patents

Schwartz's latest patents include a "Process for the hydroxycarbonylation of pentenoic acids" and a "Process for the preparation of carboxylic acids by carbonylation." Additionally, he has developed a method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of a rhodium catalyst. This innovative method involves conducting the liquid phase reaction in a first zone with a rhodium catalyst, followed by partial vaporization of the reaction mixture in a second zone. The vaporized fraction containing the carboxylic acid is purified, while the unvaporized liquid fraction containing the catalyst is recirculated to the first zone. Notably, the unvaporized fraction is contacted with carbon monoxide in a manner that prevents its return to the second zone.
