| titleOfInvention | Processes for purification and recovery of n- (3,3-dimethyl-butyl) -alpha-1-aspartyl-1-phenyl-alamine methyl-ester, and, n- (3,3-dimethyl-butyl) -alpha-1 -asset-l-phenyl-alamine methyl-ester |
| abstract | "PROCESSES FOR PURIFICATION AND RECOVERY OF N- (3,3-DIMETHYL-BUTYL) -ALFA-L-ASPARTYL-L-PHENYL-ALANINE METHYL-ESTER, E, N- (3,3-DIMETHYL-BUTYL) -ALFA- L-ASPARTYL-L-PHENYL-ALANINE METHYL-ESTER "a process is provided for the purification of N- (3,3-dimethyl-butyl) - <244> -L-aspartyl-L-phenyl-alanine methyl ester the step of contacting impure N- (3,3-dimethyl-butyl) - <244> -L-aspartyl-L-phenyl-alanine methyl-ester containing at least <244> -L-aspartyl-L-phenyl-alanine methyl -ester as an impurity, with mixed solvents having two layers of a layer formed of at least one organic solvent that does not mix homogeneously with water and a layer of water to extract N- (3,3-dimethyl-butyl) - <244 > -Laspart-L-phenyl-alanine methyl ester in the organic solvent layer. In the present invention, the desired compound can be purified or recovered efficiently in a high yield without using costly steps or operations. |
