Abstract:
A PROCESS FOR TRANSFORMING AN ALKYL AMINO ACID SALT OF A MINERAL ACID INTO THE CORRESPONDING N-ACYL AMINO ALKANOIC ACID COMPRISING NEUTRALIZING THE MINERAL ACID PORTION. THE AMMONIUM SALT IS SEPARATED OUT BY ADDING ALKADROXIDE, SEPARATING OUT THE THEREBY FORMED AMMONIUM SALT OF THE MINERAL ACID, AND ACYLATING THE REMAINING SOLUTION. THE AMMONIUM SALT IS SEPARATED OUT BY ADDING ALKANOC ACID TO THE NEUTRALIZED SOLUTION.
