PROCESS FOR REGENERATION OF HYDROGENATION CATALYSTS
The invention provides a process for regenerating a catalyst used for the ring hydrogenation of an aromatic species, especially an aromatic ester, wherein a gas stream containing a particular amount of oxygen is used for the regeneration.
METHOD FOR PROCESSING BENZENE POLYCARBOXYLIC ACID ESTERS AND USE OF SAME TO PRODUCE CYCLOHEXANE POLYCARBOXYLIC ACID ESTERS
The present invention relates to a process for purifying benzenepolycarboxylic esters and for preparing cyclohexanepolycarboxylic esters by hydrogenating the purified benzenepolycarboxylic esters. The invention further relates to benzenepolycarboxylic esters and cyclohexanepolycarboxylic esters having a small proportion of by-products, especially of dialkyl ethers, and especially to diisononyl cyclohexane-1,2-dicarboxylate having a small proportion of diisononyl ether. The invention also relates to the use of the cyclohexanepolycarboxylic esters as plasticizers, especially in products intended for human contact, such as children's toys, food packaging and medical articles.

Synthesis of building blocks and feedstocks for manufacturing renewable polymers
Disclosed are methods or processes of synthesizing building blocks and feedstocks for producing a broader range of polymers, including renewable polymers, from renewable resources such as CO.sub.2. In a process of manufacturing a renewable feedstock for polymer production, a CO.sub.2 derived lactone is prepared and processed to form the renewable feedstock. The process may include alkoxycarbonylation of the CO.sub.2 derived lactone to form a diester and hydrogenation of the diester.
