QUALITY TEST FOR POLYMERIZABLE LACTIC ACID AND METHOD FOR PRODUCING SAME. |
摘要 |
The invention relates to a test for determining the quality of lactic acid, comprising a) means for the polycondensation of the lactic acid to form a pre-polymer b) means for depolymerization to form dilactide, and c) means for carrying out analytical methods for determining the dilactide yield and/or the racemization, wherein lactic acid which fulfills the test and is suitable for polymerization exhibits a dilactide yield of > 90 % and a racemization of < 5 %. |
