Molecular formula : C5H7NO3
MW : No. 98-21-214 129.11
nature : colorless crystal. Melting point 162-163 ° C, soluble in water, alcohol, acetone and acetic acid, ethyl acetate - soluble and insoluble in ether.
Preparation : semi-synthesis, enzyme conversion and the whole synthesis. Industrial production is the primary means of glutamic acid semi-synthesis. 42% of glutamic acid solution heated at 140 ° C for 3 to be L-pyroglutamic acid as the main component of the reaction solution. By vacuum concentration, crystallization, washing, drying, derived L-glutamate coke conversion rate of 94%.
purposes : for organic synthesis intermediates, food additives.
