Embodiment 1
[0034] A kind of preparation method of full water-soluble titanium fertilizer, it comprises the following steps:
[0035] Device: The central port of a 1000mL four-neck glass flask is connected to a serpentine condenser, and the other three ports are respectively connected to a thermometer, a dropping funnel and a pH meter probe. The flask was installed in an adjustable temperature electric heating mantle magnetic stirrer (1000mL).
[0036] Weigh 500g of refined titanium solution and 75g of citric acid into a four-neck flask with a funnel, then add a magnetic stirrer and a small amount of zeolite, install the serpentine condenser and turn on the cooling return water, thermometer, and pH meter probes, and One port was closed with a glass stopper. After sealing, turn on stirring and electric heating mantle heating, start timing for 30 minutes when the temperature in the flask reaches 95°C, and keep the temperature in the flask between 95-100°C.
[0037]After the time is up, st...
Embodiment 2
[0061] A kind of preparation method of full water-soluble titanium fertilizer, it comprises the following steps:
[0062] Device: with embodiment 1.
[0063] Weigh 500g of concentrated titanium solution and 90g of mannitol into a four-neck flask with a funnel, then add a magnetic stirrer and a small amount of zeolite, install the serpentine condenser and turn on the cooling reflux water, thermometer, pH meter probe, and One port was closed with a glass stopper. After sealing, turn on stirring and electric heating mantle heating, start timing for 30 minutes when the temperature in the flask reaches 95°C, and keep the temperature in the flask between 95-100°C.
[0064] After the time is up, stop heating, keep stirring to allow the flask to cool down naturally, when the temperature in the flask drops to 45°C, take off the glass stopper and replace it with a dropping funnel, slowly add 20% ammonia water (about 250g) dropwise, continue stirring and observe the flask The pH value ...
Embodiment 3
[0070] A kind of preparation method of full water-soluble titanium fertilizer, it comprises the following steps:
[0071] Device: with embodiment 1. Weigh 400g of refined titanium solution and 90g of glucose into a four-neck flask with a funnel, then add a magnetic stirrer and a small amount of zeolite, install the serpentine condenser and turn on the cooling return water, thermometer, pH meter probe, and another The mouth was closed with a glass stopper. After sealing, turn on stirring and electric heating mantle heating, start timing for 30 minutes when the temperature in the flask reaches 95°C, and keep the temperature in the flask between 95-100°C.
[0072] After the time is up, stop heating, keep stirring to allow the flask to cool down naturally, when the temperature in the flask drops to 45°C, take off the glass stopper and replace it with a dropping funnel, slowly add dropwise sodium hydroxide solution (w / w, 10%, about 130g), keep stirring and observe the pH value ch...
