    Abstract: The invention relates to a process for continuously preparing di-C1-3-alkyl succinates by reacting succinic acid with an C1-3-alkanol in the presence of a fixed-bed heterogeneous acidic esterification catalyst in a tubular reactor at a temperature in the range of from 60 to 100°C, wherein a mixture, comprising succinic acid, C1-3-alkanol, mono-C1-3-alkyl succinate, di-C1-3-alkyl succinate and water, is formed in a mixing stage and fed to the entrance of the tubular reactor, and wherein 5 to 75% of the outlet flow rate of the tubular reactor are recycled directly to the mixing stage as a recycle stream, and the molar ratio of C1-3-alkanol to succinic acid added to the mixing zone, and not including the C1-3-alkanol and succinic acid at the recycle stream, being in the range of from 2.0 to 9.5. The invention furthermore relates to a process for separating the reactor effluent of an esterification of succinic acid with an C1-3-alkanol to give di-C1-3-alkyl succinates by distillation, wherein the separation is performed in a divided wall column in which C1-3-alkanol and water are removed in a top draw of the column, di-C1-3-alkyl succinate is removed in a side draw of the column, and wherein mono-C1-3-alkyl succinate and succinic acid are removed in a bottom draw of the column.

    Abstract: Un procedimiento de preparación en contínuo de succinatos de di-alquilo C1-3 por reacción del ácido succínico con un alcanol C1-3 en presencia de un catalizador de esterificación ácida heterogéneo de lecho fijo en un reactor tubular a una temperatura en el intervalo desde 60 a 100ºC, en el que se forma una mezcla, que comprende ácido succínico, alcanol C1-3, succinato de mono-alquilo C1-3, succinato de di-alquilo C1-3 y agua, en una etapa de mezclado y se alimenta a la entrada del reactor tubular, y en el que 5 a 75% del caudal de salida del reactor tubular se recicla directamente a la etapa de mezclado como corriente de reciclaje y estando la proporción molar de alcanol C1-3 respecto al ácido succínico adicionado a la zona de mezcla, y sin incluir el alcanol C1-3 y el ácido succínico de la corriente de reciclaje, en el intervalo desde 2,0 a 9,5.
