PROCESS FOR MANUFACTURING LACTIDE FROM PLASTICS HAVING POLYLACTIC ACID |
| 摘要 |
<p>A process for manufacturing lactide from plastics having polylactic acid (PLA-based plastics) comprises preparing PLA-based plastics, accelerating decomposition of polylactic acid in the plastics to provide low molecular weight polylactic acid, and thermal decomposing the low molecular weight polylactic acid to provide lactide. Also, the process further comprises minimizing size of the PLA-based plastics after the PLA-based plastics preparation step, and purifying lactide after thermal decomposing low molecular weight polylactic acid to provide lactide.</p> |
