| titleOfInvention | A kind of polishing purification method of N-acylamino acid or its salt |
| abstract | A method for the polishing purification of N-acylamino acid or its salt, comprises the following steps: 1) acid adding in material N-acylamino acid or its salt, is acidified to pH value less than 2, is warming up to the fusing of N-acylamino acid, is stirred to material dispersed or become emulsified state; 2) step 1) gained material cooling, to wherein N-acyl amino acid crystal or solidification, emulsification system is because the material playing surface-active action becomes solid and breakdown of emulsion, and N-acyl amino acid crystal is dispersed in water; 3) heat up, N-acyl amino acid crystal is melted, after gathering, forms organic phase, and with aqueous phase layering, leave standstill divide a water-yielding stratum.The inventive method utilizes the method for crystallization breakdown of emulsion, solves the not good problem of layering, aqueous phase and organic phase layering thorough, can desalting effect be significantly improved, the N-acylamino acid after refining or its salt saltiness is low, impurity is few. |
