    摘要： Amino acids can be purpified and/or concentrated by extracting aqueous mixtures such as fermentation broths by contacting an aqueous mixture containing amino acids with an organic solution containing a water insoluble extractant selected from the group consisting of:1. A quaternary ammonium ion having the formula: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are aliphatic, each having from 1 to 22 carbon atoms, and together have a minimum of 25 carbon atoms, and where at least three of the four R groups are at least a C.sub.4.2. A quaternary phosphonium ion having the formula: ##STR2## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined above. 3. A tertiary sulfonium ion having the formula: ##STR3## where R.sub.1, R.sub.2 and R.sub.3 each are aliphatic with from 1 to 22 carbon atoms, and together have a minimum of 24 carbons and where at least two of these groups are at least a C.sub.6.4. An organic boride ion having the formula: ##STR4## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as previously defined. 5. An organic sulfonic acid selected from the group consisting of:Organic sulfonic acids having the structural formula: ##STR5## where R.sub.5 and R.sub.6 are aliphatic hydrocarbon groups individually with from about 6 to about 22 carbon atoms, where R.sub.5 and R.sub.6 together contain at least 18 carbon atoms, and where neither R.sub.5 nor R.sub.6 are smaller than a C.sub.6 ; and organic sulfonic acids having the structural formula; ##STR6## where R.sub.7 and R.sub.8 are aliphatic hydrocabon groups containing from about 4 to about 22 carbon atoms, where R.sub.7, R.sub.8, or the sulfonic group may be attached to positions 1-8 on the aromatic rings, and where neither R.sub.7 nor R.sub.8 is smaller than a C.sub.4, and where R.sub.7 and R.sub.8 together have at least 18 carbon atoms.
