Method for recovery of α-L-aspartyl-L-phenylalanine methyl ester, L-phenylalanine and L-aspartic acid

A method for the recovery of α-L-aspartyl-L-phenylalanine methyl ester, L-phenylalanine and L-aspartic acid from the mother liquor obtained by the solid-liquid separation of a suspension of α-L-aspartyl-L-phenylalanine methyl ester crystals is disclosed.

Method for manufacture of N-formylaspartic anhydride

In a method for the manufacture of N-formylaspartic acid anhydride which comprises reacting a mixture of aspartic acid, formic acid and acetic anhydride in the presence of an entraining organic solvent, the improvement comprising adding to the mixture, prior to or during the course of reaction, an oxide, hydroxide, or a salt of a metal. The above compound is used as an intermediate in the manufacture of alpha-L-aspartyl-L-phenylalanine methyl ester which is a sweetening agent.
