| titleOfInvention | A kind of polishing purification method of N acylamino acids |
| abstract | The invention belongs to field of fine chemical, and in particular to a kind of polishing purification new method of N acylamino acids, comprise the following steps：（1）Conventional condensation is synthesized N acylamino acids；（2）Removed by the ethanol in feed liquid after vacuum distillation is by condensation reaction most of；（3）Make organic phase separated from the water by acidifying, then N acylamino acids is formed dispersion liquid with water by cooling；（4）The water in dispersion liquid is removed using diaphragm filter press, then carries out dispersion washing with the water with the quality such as material again, then filtered by filter, 3~5 dispersion washings are so repeated, dried, that is, obtain high purity N acylamino acid solid powder.The inventive method can effectively solve the problems such as prior art purification effect is poor, efficiency is low, product easily turns to be yellow and portioned product can form accessory substance with solvent. |
