Preparation and isolation of mineral acid salt of an amino methyl ester |
| abstract |
A cyclical process for producing and isolating a mineral acid salt of an amino acid methyl ester in high purity and yield from the reaction solution produced by esterifying an amino acid with methanol in methanol in the presence of a mineral acid, by cooling the resulting reaction solution to precipitate crystals of the mineral acid salt; filtering the crystals; ndrying the isolated wet crystals or washing with another organic solvent; and recycling the filtrate for reuse in the esterification reaction. |
