| titleOfInvention | Method for separating pure (meth)acrylic acid tert-butyl ester by distillation from crude (meth)acrylic acid tert-butyl acrylate |
| abstract | The invention provides a method for separating pure tertiary butyl (meth) acrylate from crude tertiary butyl (meth) acrylate by distillation, wherein the method is carried out in a dividing wall column (1). The partition wall tower (1) has effective separation internals and carburetor (7), and the partition wall (8) is arranged along the longitudinal direction of the tower to form an upper joint tower area (9), a lower joint tower area (14), Inflow section (10, 12) with side feed point (2) and discharge section (11, 13) with side discharge point (3), the tower has a number of theoretical plates in the range of 20 to 80, where the The number of theoretical plates of the dividing wall tower (1) is related to the sum of the theoretical plates in the upper joint tower area (9), the lower joint tower area (14) and the inflow section (10, 12), The side feed point (2) of the crude tertiary butyl (meth) acrylate is arranged in an area starting at least two theoretical plates above the bottommost theoretical plate and ending in at least two theoretical plates below the uppermost theoretical plate. At a theoretical plate, the side discharge point (3) of the pure tertiary butyl (meth) acrylate is arranged at least two theoretical plates above the bottommost theoretical plate and finally At a theoretical plate in an area of at least two theoretical plates below the uppermost theoretical plate, and the partition wall (8) is arranged in the tower starting at least one theoretical plate above the lowest theoretical plate and ending at the most In the area of at least one theoretical plate below the upper theoretical plate, the ratio of the amount of liquid entering the enrichment section (10) and stripping section (11) of the tower at the upper end of the partition wall (8) is set at 1: 0.2 To 1: 5. |
