Efficient production of aminoalkyl sulfonic acid using inexpensive reagents without problems such as the need for expensive equipment and the use of hydrogen peroxide which is difficult to handle safely. obtain.
- N-methyltaurine sodium salt aqueous solution (trade name: NMT50, manufactured by LE UN A), concentrate the water under reduced pressure, add 33 L of methanol, and add 3.6 kg (60.0 mol) of acetic acid Was added dropwise, and the mixture was stirred and reacted at 20 to 30 ° C for 1 hour. After completion of the reaction, the reaction solution was cooled to -10 ° C and stirred at the same temperature for 1 hour. The crystallized product was collected by filtration and dried under reduced pressure to obtain 7.4 kg of N-methyltaurine as white crystals ( Yield 97%).
- Example 3 The same operation as in Example 3 was performed, except that propionic acid was used instead of acetic acid, to obtain 7.3 kg of N-methyltaurine (95% yield).
- Example 6 Salt exchange reaction from sodium salt to ammonium salt
- Example 7 Salt exchange reaction from sodium salt to trienoammonium salt
- Example 5 The same operation as in Example 5 was performed, except that 7.9 kg (53.2 mol) of triethanolamine was used instead of 3.0 kg (53.2 mol) of potassium hydroxide, to obtain 60% N monomethylphosphorin triethanol ammonium. 23.7 kg of aqueous salt solution was obtained.
- the process for producing an aminoalkylsulfonic acid according to the present invention comprises reacting an aminoalkylsulfonic acid metal salt of an amino acid or an aqueous solution thereof, or a solution obtained by dissolving any of them in a water-soluble organic solvent with an organic acid.
- That conventional methods have, for example, it is necessary to use toxic substances or substances that are difficult to handle for safety, it is difficult to separate the target aminoalkylsulfonic acid from by-products, etc. It is possible to efficiently produce high-purity aminoalkylsulfonic acid on an industrial scale without having the problems described above.
