Abstract
Se describe un procedimiento mejorado para la preparación de productos finales aductos de condensación de bases 5 de Schiff cuyos componentes incluyen una proteína que tiene una actividad beneficiosa en animales y un o-hidroxi aldehido aromático, el cual comprende la puesta en contacto de los componentes anteriormente mencionados en un entorno acuoso a un pH de 7,0 o superior para formar una mezcla de 10 reacción en condiciones eficaces para llevar dicha reacción de condensación sustancialmente hasta su finalización, eliminando entre aproximadamente 97,0% y aproximadamente 99,9% en peso, preferentemente entre aproximadamente 98,0% y aproximadamente 99,0% en peso del agua presente durante 15 dicha reacción de condensación, siendo compatible con el mantenimiento de la integridad de los reactivos de condensación y del producto final aducto, y para asegurar un porcentaje de conversión en dicho producto final aducto de condensación, es decir con un rendimiento resultante de 20 dicho producto final aducto de condensación igual o superior al 98,5% en peso, preferentemente igual o superior al 99,5% en peso respecto al peso de los reactivos. Los o-hidroxi aldehídos aromáticos preferidos incluyen: o-vainillina, aldehído salicílico 2,3-dihidroxibenzaldehído, 25 2,6-dihidroxibenzaldehído, hidroxi-3-etoxibenzaldehido o piridoxal. Se pueden utilizar una amplia gama de proteinas. El procedimiento proporciona unos rendimientos superiores al 90% y la conversión sustancilamente cuantitativa del aldehído y la proteína en el aducto de condensación.An improved procedure for the preparation of Schiff 5-base condensation adducts end products is described whose components include a protein having beneficial activity in animals and an aromatic o-hydroxy aldehyde, which comprises contacting the components above. Mentioned in an aqueous environment at a pH of 7.0 or higher to form a reaction mixture under conditions effective to drive said condensation reaction substantially to completion, removing between about 97.0% and about 99.9% by weight , preferably between approximately 98.0% and approximately 99.0% by weight of the water present during said condensation reaction, being compatible with maintaining the integrity of the condensation reagents and the adduct final product, and to ensure a percentage of conversion in said final product adduct of condensation, that is to say with a resulting yield of 20 said end product condensation adduct equal to or greater than 98.5% by weight, preferably equal to or greater than 99.5% by weight with respect to the weight of the reagents. Preferred aromatic o-hydroxy aldehydes include: o-vanillin, 2,3-dihydroxybenzaldehyde salicylic aldehyde, 2,6-dihydroxybenzaldehyde, hydroxy-3-ethoxybenzaldehyde or pyridoxal. A wide range of proteins can be used. The procedure provides yields in excess of 90% and the substantially quantitative conversion of aldehyde and protein in the condensation adduct.
