Abstract
Se describe un procedimiento para la producción de ácido glioxílico haciendo reaccionar ácido glicólico con oxígeno en una solución acuosa en la presencia de un tamponador de amina capaz de formar un aducto químico con ácido glioxílico, y oxidasa de glicolato y catalasa inmobilizada o co-inmobilizada sobre un soporte insoluble. La reacción se lleva a cabo a un ph de 7 a 10, de preferencia de 8 a 9.5, una concentración inicial de ácido glicólico de 200 hasta 2,500 mM.A procedure for the production of glyoxylic acid is described by reacting glycolic acid with oxygen in an aqueous solution in the presence of an amine buffer capable of forming a chemical adduct with glyoxylic acid, and immobilized or co-immobilized glycolate oxidase and catalase on an insoluble support. The reaction is carried out at a pH of 7 to 10, preferably 8 to 9.5, an initial glycolic acid concentration of 200 to 2,500 mM.
