Production Methods

Formic acid (24.2g, 0.52mol), water (25mL) and aminothiourea (20g, 0.22mol) were added to a 100mL reaction flask, heated to 105 ° C for half an hour; then slowly reduced to room temperature, then reduced Slow crystallization at -10 ° C;Finally, the solid was filtered to dry to give an aldehyde amine thiourea (white solid 22.3 g, yield: 85percent).The aldehyde amine thiourea (12 g, 0.1 mol) was added to a 250 mL single-mouth bottle, and then water (130 mL) and sodium carbonate (21.2 g, 0.25 mol) were added, and the mixture was heated to 100 ° C for 4 hours;Then slowly reduce to room temperature, adjust the pH value to 4-5 with dilute hydrochloric acid, then slowly stir at -10 °C, slowly devitrify; filter out the solid, dry, 5.6 g of a white solid were obtained in a yield of 55percent.
