| titleOfInvention | A kind of lactic acid oligomer synthesis system and synthesis method with adjustable degree of polymerization |
| abstract | The invention discloses a system for synthesizing lactic acid oligomers and a method for synthesizing the oligomer of lactic acid capable of regulating the degree of polymerization. The feed port is connected; the side line discharge port of the second reactive distillation column is connected to the reflux system, and the outlet of the tower kettle is connected to the extraction pipe of the second tower kettle; the reflux system includes a first condenser, and the inlet of the first condenser is connected It is connected with the side discharge port of the second reactive rectification tower, and the outlet of the first condenser is connected with the tower bottom reflux port of the first reactive rectification tower and the column top reflux port of the second reactive rectification tower respectively through pipelines. . The invention realizes the removal of free water and the generation of lactic acid oligomerization intermediates through the first reactive rectification column, and then realizes the removal of water and lactic acid oligomerization intermediates generated by the reaction through the second reaction rectification column, so that the distribution of the degree of polymerization is relatively concentrated. The lactic acid oligomers produced by the product solve the problem of wide distribution of the degree of polymerization of lactic acid oligomers, and provide high-quality raw materials for subsequent depolymerization reactions. |
