| titleOfInvention | Obtaining pure butyl acrylate from crude butyl acrylate by distillation, wherein butyl is n-butyl or isobutyl |
| abstract | Pure butyl acrylate is obtained from the crude butyl acrylate by distillation, wherein butyl is n-butyl or isobutyl, the method comprising the steps of: In one bulkhead tower (1) comprising: a bulkhead (8) arranged in the longitudinal direction of the tower, in a common upper tower area (9); A common lower tower area (14), feeds (10, 12) with side feed points (2) and discharges (11, 13) with side discharge points (3) are formed. Wherein the column has a theoretical separation plate number in the range of 20 to 80, wherein the theoretical separation plate number of the partition tower (1) is the theoretical separation plate number in the common upper column region (9). And a theoretical separation stage in the common lower tower area (14); ), The side feed point (2) for the crude butyl acrylate starts from the theoretical separation stage at least two above the bottom theoretical separation stage and A side discharge point (3) for the pure butyl acrylate is arranged on the theoretical separation stage in a region ending with at least two theoretical separation stages below the theoretical separation stage, Disposed on a theoretical separation stage in a region starting from at least two theoretical separation stages above and ending with at least two theoretical separation stages below the top theoretical separation stage, and said partition wall (8) , Starting from the theoretical separation stage at least one above the bottom theoretical separation stage and ending with the theoretical separation stage at least one below the top theoretical separation stage, wherein the column of the column is A method characterized in that the ratio of the liquid amount at the upper end of the partition (8) to the shrinking part (10) and the collecting part (11) is adjusted in the range of 1: 0.2 to 1: 5. . |
