Abstract

A process for the co-production of dialkyl maleate and dialkyl succinate in which a feed comprising monoalkyl maleate and a feed comprising monoalkyl succinate are supplied to an esterification reactor where esterification occurs and dialkyl maleate and dialkyl succinate are recovered from the esterification reactor, wherein at least a portion of the feed comprising monoalkyl maleate is supplied to the esterification reactor at a point above the point at which the feed comprising monoalkyl succinate is supplied. (Figure 1)
