Patent abstract
The invention relates to a process for purifying lipoic acid, which comprises adding to a solution of lipoic acid at least 0.1 times the amount of an adsorbent, based on the mass of lipoic acid to be purified, and subsequently removing the adsorbent. It is possible in this way to provide racemic or nonracemic lipoic acid with an oligomer content below 1% by weight, for example from 0.1 to 1% by weight.
