    摘要: The present invention is an improved process for the synthesis of asparagine, a non-essential amino acid useful in food and medical applications. The process utilizes mineral acid to make an intermediate beta-methyl aspartate from a reaction mixture of aspartic acid and methanol. The intermediate product is then amminated in situ and asparagine collected with no need for an isolation step of the intermediates.
