PROCESS FOR THE PRODUCTION OF CARNITINE FROM BETA-LACTONES |
| 摘要 |
The invention relates to a method for the production of L-carnitine, wherein a β-lactone, which is a 4-(halomethyl)oxetane-2-one, is converted into carnitine with trimethylamine (TMA), wherein the β-lactone is not subjected to a basic hydrolysis step before being contacted with the trimethylamine. The invention also relates to a carnitine having a unique impurity profile. |
