| titleOfInvention | Method for separating pure butyl acrylate by distillation from crude butyl acrylate having n-butyl or isobutyl group |
| abstract | The present invention provides a method for separating pure butyl acrylate from crude butyl acrylate which is n-butyl or isobutyl by distillation, wherein the method is performed in a partition wall column (1), and the intermediate The wall tower (1) has effective separation internals and carburetor (7), and its intermediate wall (8) is arranged along the longitudinal direction of the tower to form an upper combined tower area (9), a lower combined tower area (14), The inflow section (10, 12) of the side feed point (2) and the discharge section (11, 13) with the side discharge point (3). The tower has a number of theoretical plates in the range of 20 to 80, among which The number of theoretical plates of the 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 butyl acrylate is arranged at a theoretical plate in a region starting at least two theoretical plates above the bottommost theoretical plate and ending at least two theoretical plates below the uppermost theoretical plate. The side discharge point (3) of pure butyl acrylate is arranged at least two theoretical plates starting above the bottommost theoretical plate and ending at the uppermost theory At least one theoretical plate in the area of at least two theoretical plates below, and the partition wall (8) is arranged in the tower starting at least one theoretical plate above the bottommost theoretical plate and ending at least below the uppermost theoretical plate In a region of a theoretical plate, the ratio of the amount of liquid entering the enrichment section (10) and the stripping section (11) of the tower at the upper end of the partition wall (8) is set to 1: 0.2 to 1: 5. Within range. |
