| titleOfInvention | Recycling of lactic acid by-products |
| abstract | (57) [Problem] To provide a novel method for obtaining lactic acid by regenerating by-products generated in a lactic acid-based composition manufacturing process and obtaining lactide and polylactic acid of any optical purity using the regenerated lactic acid. The purpose is to provide. SOLUTION: The present invention provides lactide by depolymerizing a lactic acid prepolymer such as a lactic acid component in a condensed water in a step of directly synthesizing a lactic acid prepolymer or polylactic acid, a residue, a process washing liquid, and a vacuum pump drainage liquid. Forming and processing polylactic acid, such as waste in the process of purifying lactide, such as residue in the process, process cleaning liquid, and vacuum pump waste liquid, and waste polymer in the process of polymerizing lactide to obtain polylactic acid, such as waste liquid, residue, and process cleaning liquid Loss in the process, waste polymer in the market Are racemized in the presence or absence of a catalyst to obtain a substantially optically inactive lactic acid component. Then, an optically inactive lactide or polylactic acid is produced from the optically inactive lactic acid component, and the produced lactide or polylactic acid is mixed with an arbitrary ratio of lactide or polylactic acid having an optical purity of 90 to 100% ee, and optionally mixed. To obtain lactide or polylactic acid having an optical purity of |
