| titleOfInvention | A kind of method using organic solvent production glycine |
| abstract | The present invention provides a kind of process for cleanly preparing of glycine, and glycine is produced using glycolic solvents (ethylene glycol, propylene glycol, butanediol) or diol, derivatives solvent (glycol monoethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether) and methanol (or ethyl alcohol) organic solvent.After adding in organic solvent, catalyst methenamine in the reactor of production glycine, monoxone is added in, then slowly leads to ammonia, carries out the reaction of synthesis glycine.Glycine crystals are filtered out under 50 DEG C of 75 DEG C of temperature conditions after reaction, glycine product is obtained after methanol (or ethyl alcohol) washing, filtering, drying.After filtered fluid frozen cooling, ammonium chloride and the mixed crystal solid containing a small amount of glycine is obtained by filtration, ammonium chloride product is obtained by washing.Reaction dissolvent recycles. |
