1. A process for the production of 2-butoxyethyl benzoate, the process comprising: (a) contacting benzoic acid and 2-butoxy ethanol under reaction conditions to produce a crude product comprising 2-butoxyethyl benzoate and impurities; (b) feeding at least a portion of the crude product to a distillation column comprising a dividing wall or a pasteurizing section; removing an overhead stream and a bottoms stream from the distillation column, and removing a side draw stream from the distillation column; wherein, in the case where a dividing wall is present, the crude product enters the dividing wall distillation column on an opposing side of the dividing wall from the side draw stream. |
