摘要： Embodiments relate to a continuous process for the production of hydroxyethylpiperazine that includes feeding neat piperazine, recycled piperazine, and ethylene oxide to a reactor to form crude hydroxyethylpiperazine, in which the reactor is a continuous stirred tank reactor or a plug flow reactor. The process further includes continuously feeding the crude hydroxyethylpiperazine from the reactor to a distillation system that includes at least one distillation column, the distillation system produces at least a recycled piperazine stream and a hydroxyethylpiperazine stream, the recycled piperazine stream includes the recycled piperazine that is fed to the reactor to form the crude hydroxyethylpiperazine, and the hydroxyethylpiperazine stream includes at least 60 wt% of hydroxyethylpiperazine based on a total weight of the hydroxyethylpiperazine stream.

摘要： A process for preparing a divinylarene dioxide including the steps of: (a) feeding one or more feed streams of the following reactants into a reactor system: (i) at least one divinylarene, (ii) at least one oxidizing agent, and (iii) at least one solvent to form a reaction mixture in the reactor system; (b) continuously reacting together the one or more feed streams of the reactants of step (a) in the reaction mixture; and (c) controlling heat removal of the reaction mixture as the reactants of step (b) react together; wherein the heat removal is sufficient to provide a residence time of the reactants in the reaction mixture of less than about 180 minutes residence time of the reactants in the reaction step (b); and an apparatus for preparing a divinylarene dioxide.
