Process for separating leucine, isoleucine and valine

A solution of leucine, isoleucine and valine is concentrated at a pH-value of from 1.5 to 2.0 to produce a mother liquor enriched with isoleucine and valine and a solid phase enriched with leucine. Concentrated hydrochloric acid is added to the mother liquor enriched with isoleucine and valine and,...

Zusammenfassung:A solution of leucine, isoleucine and valine is concentrated at a pH-value of from 1.5 to 2.0 to produce a mother liquor enriched with isoleucine and valine and a solid phase enriched with leucine. Concentrated hydrochloric acid is added to the mother liquor enriched with isoleucine and valine and, after concentration, a mother liquor enriched with valine and leucine and a solid phase enriched with isoleucine are obtained.
