What are the precautions for using Nitrilotriacetic Acid NTA?
Nitrotriacetic acid (NTA), when using, all kinds of precautions must be observed.
First, it is related to safety protection. This substance is irritating, touches the skin, eyes, or causes discomfort. Therefore, when using it, wear suitable protective equipment, such as gloves and goggles. If you accidentally touch it, rinse it with a lot of water quickly, and seek medical attention if necessary.

What are the environmental impacts of Nitrilotriacetic Acid NTA?
Nitrile triacetic acid (NTA) has a significant impact on the environment. If this substance is dispersed between heaven and earth, it is involved in a wide range.
First, in water, NTA may combine with many metal ions to form coordination compounds. This has a great impact on the distribution and migration of metal ions in water. And if the amount is too much, it may cause the risk of eutrophication of water bodies, and the reproduction of aquatic organisms is also affected by it. Aquatic plants may grow wildly, causing ecological imbalance in water bodies, running the living space of fish and shrimp, or reducing biodiversity sharply.
Second, in soil, NTA will change the form and activity of metal elements in soil. Soil has its own ability to adjust itself to nourish all things. However, the intervention of NTA may break its balance. After it combines with metal ions, it may affect the uptake of nutrients by plant roots. Plants depend on soil nutrients for growth, and nutrient uptake is blocked, resulting in stunted growth and development, or the appearance of withering and reduced yield.
Third, in the atmospheric environment, although the direct impact of NTA is rare, its role in the surface environment is also indirectly involved in the atmosphere. If soil plants are affected by it, photosynthesis or change, which in turn affects the exchange of oxygen and carbon dioxide in the atmosphere, and there may be subtle but not negligible changes in the regional climate.
Furthermore, the process of NTA degradation in the environment cannot be ignored. Its degradation products may also have biological activities, which still have an impact on the surrounding ecology. And if the accumulation of NTA in the environment gradually exceeds the self-purification ability of the environment, it will be difficult to restore the ecological disaster in the long run. Therefore, the use and discharge of NTA should be done with caution to ensure the safety of the environment and ecological balance.
What are the production methods of Nitrilotriacetic Acid NTA?
The preparation method of nitrilotriacetic acid (NTA) is different in the past. The common ones are as follows.
One is to react with chloroacetic acid with sodium cyanide and sodium hydroxide. Chloroacetic acid first reacts with sodium hydroxide to form sodium chloroacetate. The reaction formula is: $ClCH_ {2} COOH + NaOH\ longrightarrow ClCH_ {2} COONa + H_ {2} O $. Then, sodium chloroacetate and sodium cyanide undergo nucleophilic substitution to obtain sodium cyanoacetate. The reaction formula is: $ClCH_ {2} COONa + NaCN\ longrightarrow NCCH_ {2} COONa + NaCl $. Finally, through the hydrolysis step, the cyano group is converted to the carboxyl group to obtain NTA. The hydrolysis reaction formula is: $3NCCH_ {2} COONa + 3H_ {2} O + H_ {2} SO_ {4}\ longrightarrow N (CH_ {2} COOH) _ {3} + Na_ {2} SO_ {4} + 3NH_ {3}\ uparrow $. This process needs to pay attention to the control of the reaction conditions. Sodium cyanide is highly toxic, and the operation must be careful to prevent leakage.
The second is to use iminodiacetonitrile as a raw material. Iminodiacetonitrile is hydrolyzed under acidic conditions to obtain NTA. The hydrolysis reaction is as follows: $NCCH_ {2} NHCH_ {2} CN + 3H_ {2} O + H_ {2} SO_ {4}\ longrightarrow N (CH_ {2} COOH) _ {3} + (NH_ {4}) _ {2} SO_ {4} $. The raw materials for this method are relatively easy to obtain, and the hydrolysis step is more critical. It is necessary to adjust the appropriate acidity and temperature to ensure the smooth progress of the reaction and improve the yield.
The third is to use formaldehyde, sodium cyanide and ammonia as raw materials. Formaldehyde is first added to sodium cyanide to generate hydroxyacetonitrile. The reaction formula is: $HCHO + NaCN\ longrightarrow HOCH_ {2} CN + NaOH $. Then, hydroxyacetonitrile reacts with ammonia to produce iminodiacetonitrile, and then hydrolyzes to obtain NTA. This route of raw materials is common, but the reaction steps are slightly more, and the connection and condition control of each step are very important, which is related to the purity and yield of the final product.
