Synthesis

Take 10.94kg of citric acid, add 44L of distilled water, stir to dissolve, filtered, filtrate temperature to 40 ~ 42 ; another zinc oxide (100 mesh) 6.35kg, add 26L of distilled water, stirred into a dilute pasty suspension, 100 rpm under vigorous stirring to gradually add the citric acid solution, continue to stir and keep warm at 40 ~ 42 until the reaction solution is clear, continue to stir! 5 minutes, add 0.1% activated carbon stirring for 10 minutes, while hot filtered, filtrate placed at room temperature for 24 ~ 48 hours, pour off the supernatant, filtration, collection of precipitated crystals, the crystals will be washed twice with distilled water to the washings for pH = 6, pumped dry, placed at 60 C drying, that is, to obtain the white zinc citrate,. The collection of zinc citrate was 14.2 kg, the yield was 82.1%, and the purity reached 98.2%.
