摘要: Process for racemization of amino acids by use of a ketone and an organic acid such as acetic acid. In particular, a process for resolution of free .alpha.-amino acids with in situ racemization. The resolution of 4-hydroxyphenylglycine and 3,4-dihydroxyphenylglycine with 3-bromocamphor-9-sulphonic acid with in situ racemization are specifically mentioned.
