Steps:
1-6 Example 2
First, the glufosinate hydrochloride (1 mol) was added to 100 ml of water and 300 ml of methanol, and thetemperature was raised to 60 ° C to dissolve it, and the temperature was lowered to 30 ° C, and 18.7 g ofammonia gas was introduced; then, the mixture was stirred at room temperature for 20 minutes. The temperaturewas lowered to -5 ° C, stirred for 3 hours, and the precipitated crystals were filtered, washed with methanol anddried to obtain 185.1 g of purified glufosinate monohydrate crystals, yield 93%, purity 97.9%.
