Diethyl hydroxylamine (DEHA) is an inorganic chemical that is utilized in the polymer industry or as a corrosion inhibitor in the metal industry.
Diethyl hydroxylamine can be used as a deoxygenating agent or Oxygen scavenger. This chemical is a member of the hydroxylamine family, whose appearance is a colorless liquid under standard conditions, at room temperature, and at normal atmospheric pressure.
Diethyl hydroxylamine (DEHA) dissolves well in water, it is chemically stable and environmentally friendly, is non-toxic and its use is not harmful to the environment.
Diethyl hydroxylamine (DEHA) can easily remove oxygen in solutions and this property of this chemical is widely used in water and wastewater treatment industries and boilers.
The use of this amine in the industry has advantages, it can increase the useful life of the equipment and reduce repair costs.
In the following text, we will become more familiar with the properties’ main uses of DEHA.
Physical and chemical properties of Diethyl hydroxylamine (DEHA):
DEHA as a reducing agent can show good performance, this chemical decomposes at high temperatures and it’s also flammable. the chemical formula of this amine is (CH3CH2)2NOH, it smells like ammonia, and its chemical structure is as follows:
It is one of the most popular chemical agents in the water treatment industry like Cyclohexanone. DEHA is relatively volatile and can evaporate with water to prevent corrosion of metals and steam systems and boilers.
The most important physical and chemical properties of diethyl hydroxylamine are summarized in the table below:
|Name||Diethyl hydroxylamine (DEHA)|
|Molecular weight (g/mol)||89.14|
|Melting point (°C)||-25|
|Boiling point (°C)||127.6|
|Solubility in water||Completely soluble|
Synthesis and production of Diethyl hydroxylamine (DEHA):
Specifically, DEHA can be produced by the process of esterification of adipic acid and ethyl hexanol without the use of a solvent.
Triethylamine and peroxide are also used in the production of this chemical, Distillation, filtration, and purification processes are also used after the completion of the reaction.
This inorganic chemical is produced and marketed in two different grades, Shanghai Chemex Company offers you DEHA with the highest quality and the most appropriate price.
Application and uses of DEHA:
The deoxygenation properties of this amine are used in water treatment processes like water treatment chemicals. Dissolution of this DEHA in water can control the amount and level of oxygen in the solution.
In polymerization processes, this product is used as a barrier, in the photography industry, dozens are used as color stabilizing agents in various photos.
Specifically, the oxygen in the water used in power plants, refineries, and equipment of water treatment systems is known as a destructive factor that can cause undesirable phenomena in the long-term run.
- The risk of corrosion due to the presence of oxygen in the drinking water has caused chemists to use oxygen scavengers to remove this substance, tens of one of these chemicals.
- In the past, hydrazine was utilized to remove oxygen from water, but over time, proving that hydrazine can be carcinogenic, chemists have considered using alternatives to hydrazine.
- Carbohydrazide and specifically diethyl hydroxylamine are among the substances used as substitutes in these industries.
Diethyl hydroxylamine (DEHA) does not have food certification from the Food and Drug Administration. LD50 numbers for Diethyl hydroxylamine are 2190 mg / kg in rats and 1300 mg / kg in rabbits.
When working with this inorganic material, pay attention to all safety and health points, use safety glasses, gloves, and special clothes.
Avoid swallowing DEHA seriously as it can have adverse effects and inflammation of the gastrointestinal tract.
Avoid inhaling vapors from this chemical, irritation of the respiratory system, lungs and headache and dizziness are the effects of inhaling vapors.
Effects of DEHA on the environment:
In general, after using DEHA, its effects may remain in the user environment, in general, for fish and aquatics, this inorganic compound is considered toxic and is harmful to aquatics health.
The use of this substance should be reduced as much as possible and it should be used as required and in standard amounts, Excessive consumption can negatively affect its performance and adverse effects on the environment in the long run.
Dosage of DEHA is related to:
- The dosage of oxygen that is presented in the system;
- The final point of the product;
- Operational parameters.
Transporting and storage:
Store this chemical in a cool and dry place and away from heat and sunlight.
