실험 절차

According to a preferred embodiment of the present invention, in the first step, to DL-carnitine is added dibenzoyl-L(+)tartaric acid and a lower alcohol, the mixture is dissolved under heat to form dibenzoyl-L(+)tartarates of D-carnitine and L-carnitine, and subsequently the tartarates are cooled to fractionally crystallize dibenzoyl-L(+)tartarate of L-carnitine.
