ABSTRACT:
There is disclosed a process for the racemization of amino acids and derivatives thereof. The racemization process of the present invention uses an aromatic aldehyde-containing polymer made from the reaction of a hydroxy-aromatic aldehyde with a chloromethylated vinylbenzene polymer under reaction conditions to form an aromatic aldehyde-containing polymer wherein the aldehydic moiety is linked to the polymer through an ether linkage. There is also disclosed a process for the production of the racemization catalyst. Another embodiment of the invention comprises a process for the promotion of the racemization reaction wherein a tertiary amine-containing resin is used as a promoting agent.
