METHOD FOR OBTAINING PURE TERT-BUTYL (METH)ACRYLATE FROM RAW TERT-BUTYL (METH)ACRYLATE BY DISTILLATION

METHOD FOR OBTAINING PURE TERT-BUTYL (METH)ACRYLATE FROM RAW TERT-BUTYL (METH)ACRYLATE BY DISTILLATION

A process for isolating pure tert-butyl (meth)acrylate from crude tert-butyl (meth)acrylate by distillation, wherein the process is carried out in a dividing wall column having separation-active internals and a vaporizer and in which a dividing wall is arranged in the longitudinal direction of the c...

description A process for isolating pure tert-butyl (meth)acrylate from crude tert-butyl (meth)acrylate by distillation, wherein the process is carried out in a dividing wall column having separation-active internals and a vaporizer and in which a dividing wall is arranged in the longitudinal direction of the column to form an upper joint column region, a lower joint column region, an inflow section having a side feed point, and an offtake section having a side offtake point, where the column has from 20-80 theoretical plates and the ratio of the amount of liquid at the upper end of the dividing wall going to the enrichment section and the stripping section of the column is set in the range from 1:0.2 to 1:5.
